Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
The invention aims to design a novel burner by utilizing the combustion characteristic of high-temperature air and apply the novel burner to a gas water heater, so that the gas water heater can effectively reduce the emission of pollutants (CO and NOx) and reduce the noise of the gas water heater.
The invention provides a burner which is suitable for gas water heaters, and related products and equipment such as gas wall-mounted furnaces and the like which use high-temperature hot water generated by gas combustion for household bathing, heating and the like.
The burner of the invention can be applied to conventional burners, catalytic burners and high-temperature air burners. Among them, the high temperature air burner (high temperature air burner) is called "MILD and deep low oxygen dilution combustion", and the soft combustion is a new combustion method, also called MILD combustion. The main characteristics of the combustion are as follows: the chemical reaction mainly takes place in a high-temperature low-oxygen environment, the temperature of the reactants is higher than the autoignition temperature of the reactants, the maximum temperature rise in the combustion process is lower than the autoignition temperature of the reactants, and the volume fraction of oxygen is diluted by combustion products to an extremely low concentration, usually 3-10%. Compared with conventional combustion, in the combustion state, the pyrolysis of fuel is inhibited, the flame thickness is thickened, and the flame front surface disappears, so that the temperature of the whole hearth is very uniform during the combustion, and the emission of pollutants NOx and CO is greatly reduced. The existing fully premixed gas water heater adopts a fan to suck air, mixes the air with gas and then sprays the gas into a combustion chamber; the existing atmospheric gas water heater is forced-pumping type that air is injected through gas and then is injected into a combustion chamber, and forced-drum type air is sucked through a supercharging device and then is respectively injected into the combustion chamber. That is, the existing burners usually need to be provided with a fan to suck air into the burner to realize combustion. In the process of the operation of the gas combustion heater, noise is easy to generate, wherein the noise mainly comes from combustion noise and fan noise. The combustion noise is that strong hot smoke heated during combustion generates violent oscillation in a closed combustion chamber so as to make louder sound. The fan noise is caused by the fact that the gas water heater needs to be constantly supplemented with air during the combustion of gas, and the fan continuously rotates to cause the shell to resonate, so that mechanical noise is generated. This brings great inconvenience to the user's use to, the fan continues to produce resonance and easily damages the water heater.
To this end, referring to fig. 1 to 7, in an embodiment of the present invention, the burner includes:
a combustion body 10;
an air storage device 20 communicated with the combustion body 10 for storing air;
an air supply unit 30 for compressing the air and supplying the compressed air to the air storage device 20 for storage, and controlling the air stored in the air storage device 20 to be supplied to the combustion body 10;
and an electronic control assembly 40 electrically connected to the air supply assembly 30, wherein the electronic control assembly 40 is configured to control the air supply assembly 30 to store air in the air storage device 20 when a prepared air storage command is triggered.
In this embodiment, the combustion main body 10 includes a casing, the casing is sequentially formed with a first combustion chamber 11 and a second combustion chamber 12, and the casing is further provided with a smoke outlet; a preheating burner installed in the first combustion chamber 11; a heat exchanger located between the smoke exhaust and the second combustion chamber 12; the burner further comprises an electric control assembly 40, and the combustion main body 10 further comprises a water inlet pipe for introducing water into the gas water heater, a hot water outlet pipe for providing hot water to the outside, a smoke exhaust pipe connected with a smoke exhaust port, a gas inlet pipeline for introducing gas and an air inlet valve, which are all available and are not described in detail herein. Wherein the preheating burner is used for heating the gas of the MILD combustion chamber. The preheating burner may be a honeycomb structure effective to prevent backfire during combustion, for example, the gas water heater may further include an igniter for igniting the gas injected from the preheating burner. The electric control assembly 40 is used for controlling the preheating burner to burn when the gas water heater is started, and the gas and the air entering the first combustion chamber 11 are ignited and ignited by the preheating burner, so that the mixed gas mixed with the gas and the air is burned to heat the air in the first combustion chamber 11, and high-temperature flue gas is formed. It will be appreciated that the air in the first combustion chamber 11 can be heated to a target temperature, i.e., the above-mentioned preset temperature, by controlling the heating temperature, so that the high-temperature preheating of the air is realized. After the high-temperature gas subjected to high-temperature preheating is sent into the second combustion chamber 12, fuel gas is injected into the second combustion chamber 12, the fuel gas is combined with the high-temperature gas, and the high-temperature gas ignites the fuel gas, so that MILD combustion is formed in the second combustion chamber 12. The first combustion chamber 11 is a preheating combustion chamber, and the second combustion chamber 12 is a high-temperature air combustion chamber.
The electronic control assembly 40 may control the flow rate of the gas delivered to the second combustion chamber 12 when the air storage device 20 delivers the gas to the first combustion chamber 11 and the second combustion chamber 12, respectively, so that the gas is heated to a preset target temperature in the first combustion chamber 11 and then delivered to the second combustion chamber 12 for high-temperature air combustion. In this embodiment, the electronic control assembly 40 includes a main controller and a driving assembly, such as a motor and a driving circuit, for driving the gas valve and the air compressor, and the electronic control assembly 40 may further include a water inlet temperature sensor for detecting a water inlet temperature, a water outlet temperature sensor for detecting a water temperature, a flame temperature sensor for detecting a flame temperature, a flow meter for detecting a water inlet flow, and the like.
An air inlet channel and a gas flow channel are further formed in the combustion main body 10, and in some embodiments, a mixing channel may be further provided, and the mixing channel is respectively communicated with the air inlet channel and the gas flow channel. The air supply assembly 30 is disposed in the air inlet duct, and during the air storage process, the air supply assembly 30 draws air outside the burner into the air inlet duct and compresses the air to be stored in the air storage device 20, and during the air storage process, the air supply assembly 30 can compress the air as much as possible to meet the use requirements of users, and the air storage process can be performed before the users use the water heater, for example, when the users go out and are far away from the water heater, or big data analysis is performed according to the use conditions of the users, the use habits of the users are calculated, and the air storage is performed at the peak with the time when the users use the water heater. Of course, in other embodiments, the processing may also be performed based on an instruction actively triggered by the user, which is not limited herein.
The air storage device 20 has a first air outlet and a second air outlet, wherein the first air outlet is used for delivering air to the first combustion chamber 11, and the second air outlet is used for delivering air to the second combustion chamber 12. During the operation of the water heater, i.e., the combustion body 10, by the user, the electronic control unit 40 can control the air supply unit 30 to stop, i.e., the air supply unit 30 stops sucking and compressing air from the outside of the burner, and the air required by the combustion body 10 during the combustion process can be supplied from the air storage device 20. Of course, during the operation of the combustion main body 10, the electronic control assembly 40 may also control the air feeding assembly 30 to operate simultaneously, so that the air feeding assembly 30 draws the air outside the burner into the intake air duct and compresses the air to be stored in the air storage device 20. That is, there are three operation modes between the air storage device 20 and the air supply assembly 30, an operation mode in which the air supply assembly 30 is used alone for air storage, an operation mode in which the air storage device 20 is used alone for supplying compressed air to the combustion body 10, or an operation mode in which the air storage device 20 and the air supply assembly 30 are operated simultaneously. In addition, the capacity of the air storage device 20 may be set according to the actual needs of the user, for example, when the user uses hot water more frequently, the capacity of the air storage device 20 may be set to be larger, and vice versa, the capacity may be set to be smaller. Alternatively, the air storage device 20 may be set according to the frequency of the user's use, for example, to store the amount of air used by the user only once in advance, or to store the amount of air twice or more. The prepared gas storage instruction setting instruction can be any one or combination of a timing on/off gas supply instruction, an ambient light on/off gas supply instruction, a key-triggered on/off gas supply instruction and a remote on/off gas supply instruction. For example, when setting the air supply instruction function, the user may set the on-time, the off-time, and the set time duration of the air storage device 20 and the air supply assembly 30 through the mobile terminal (remote controller, mobile phone, smart band, smart watch, tablet computer), and then send the corresponding control instruction to the burner through the mobile terminal, and the user may select the time duration through the operation button disposed on the burner housing, and set the on-time, the off-time, and the set time duration of the air storage device 20 and the air supply assembly 30. When the control is carried out through the on/off air supply instruction of the ambient light, the current day, night, the rest time of a user and the like can be determined, and the on/off is determined according to the ambient light signal. In the remote air supply/cut-off instruction, the user can control the on/off of the air storage device 20 and the air supply assembly 30 through the mobile terminal, APP, etc. When the automatic on/off setting condition is satisfied, the main controller and other circuit modules and components in the burner configure corresponding parameters, such as the time for the air supply assembly 30 and the air storage device 20 to start working, the time for finishing working, the different pressure of the delivered air at each stage, the duration thereof, and the like according to the prepared air storage command, so as to respond to the prepared air storage function set by the user and realize the intelligent control of the burner.

In addition, the following conditions are also achieved, and the high-temperature preheating of air and the matching of high-speed jet flow are the main modes for realizing high-temperature air combustion; the technical key for maintaining high-temperature air combustion is to entrain high-temperature flue gas and dilute combustion air jet. Preheating the MILD intake air and increasing the speed of the MILD intake air are critical in order to create MILD combustion within the combustion chamber of the water heater. The existing fully premixed gas water heater adopts a fan to suck air, mixes the air with gas and then sprays the gas into a combustion chamber; the existing atmospheric gas water heater is strongly pumped, air is injected through gas and then is injected into a combustion chamber, and a strong drum type air heater is sucked through a fan and then is respectively injected into the combustion chamber. The existing gas water heaters adopt air distribution modes, the speed of airflow sprayed into a combustion chamber is usually not more than 2m/s, and the high-speed jet state required by MILD combustion cannot be achieved.

Wherein, the supercharging device 31 is an air compressor. By controlling the operation of the supercharging device 31, the total amount of air taken into the first combustion chamber 11 and the second combustion chamber 12 can be controlled.
In this embodiment, the air compressor may pressurize the air output by the supercharging device 31, so that the air jet speed output to the second combustion chamber 12 may be increased.
In the working process of the burner, the supercharging device 31 respectively conveys gas to the first combustion chamber 11 and the second combustion chamber 12, and when the gas is conveyed to the second combustion chamber 12, the pressure of the gas conveyed to the second combustion chamber 12 can be adjusted, so that the pressure of the gas conveyed to the second combustion chamber 12 is increased, and further the condition that the gas jet speed is controlled to meet the MILD combustion condition is ensured, so that when the gas is injected to the second combustion chamber 12, the gas is combined with high-temperature gas, the high-temperature gas ignites the gas, MILD combustion is formed in the second combustion chamber 12, and the pressurized gas is conveyed to the second combustion chamber 12 through the supercharging device 31, so that the gas conveyed from the second combustion chamber 12 is in a high-speed jet state, and the MILD combustion requirement is met. And a entrainment effect is formed in the second combustion chamber 12, so that an injection combustion area and a flue gas reflux area are formed in the second combustion chamber 12, part of high-temperature flue gas (waste gas rich in N2 and CO 2) is intensively circulated in the second combustion chamber 12 to dilute reactants, and then the injected fuel gas and air are fully diluted to form lower oxygen concentration, reduce the combustion reaction speed, maintain higher temperature of the second combustion chamber 12, ensure that the temperature is higher than the auto-ignition point of the fuel, realize auto-ignition and further realize high-temperature air combustion. The electronic control assembly 40 may also control the preheat burner to cease operation when the MILD burner temperature reaches above the MILD combustion light-off temperature while MILD combustion is occurring.

In addition, the backflow of high-temperature flue gas is realized through high-speed jet entrainment, the temperature of the second combustion chamber 12 can be kept higher than the self-ignition point of the fuel, and the combustion can be maintained as long as the fuel gas is continuously introduced. The heat after burning can exchange heat with the heat exchanger of the gas water heater to realize the hot water production.

It should be noted that the target temperature of the high-temperature preheated air cannot be too low, and cannot be lower than 600 degrees celsius as much as possible, and generally, the target temperature is controlled to be 600 to 1200 degrees celsius, so that when the high-temperature gas contacts with the fuel gas in the second combustion chamber 12, better automatic combustion is realized, and ignition are no longer needed. Wherein, the target temperature can be achieved by controlling the heating time, controlling the ratio of the fuel gas and the air, preserving the heat, increasing the staying time of the high-temperature gas in the first combustion chamber 11, and the like.

Alternatively, the air and the gas are pressurized separately and then delivered to the second combustion chamber 12 through an air pipe and a gas pipe, respectively. When the gas and air are mixed first, a premixer may be used, which is arranged in the combustion chamber, for example in the first combustion chamber 11 or the second combustion chamber 12, because the mixed gas containing gas and air is provided by the pre-mixer, the mixed gas is ignited and burnt by the pre-heating burner, the high-temperature air preheating is realized, and then the mixed gas is pressurized to form the injection gas with a certain jet velocity to generate the entrainment effect by matching, so that the high-temperature flue gas flows back, on one hand, the temperature is kept to be higher than the self-ignition point of the fuel, so that the fuel gas in the combustion chamber can be self-ignited, on the other hand, the diluted air is sucked by the jet flow to ensure that the oxygen concentration is lower than a certain value, so that the uniform combustion is realized, therefore, high-temperature air combustion occurs in the combustion chamber, the MILD combustion requirement can be met, and the emission of CO and NOx is reduced.
