Description
Technical field
The present invention relates to combustion and steam generation equipment technical field, particularly a kind of combustion and steam generation equipment.
Background technology
At present, combustion and steam generation equipment has been widely used in hotel, restaurant, dining room, hotel, for hotel provides steam with steaming or steaming foods or Saunas.A kind of gas steam engine that existing gas steam engine is announced on March 11st, 2015 as China Patent No. 201420402460.2, it comprises gas flow adjusting device, fire row, booster water pump, water proportioning valve, hydrotreater and heat exchanger, described booster water pump, water proportioning valve, heat exchanger is connected by inlet channel, described gas flow adjusting device is connected with fire row by admission line, described fire row is located at below heat exchanger, described hydrotreater is located on inlet channel, but existing gas steam engine still has the following disadvantages: one is the heat exchanger in series in existing gas steam engine unit, along with the constantly reheat heat exchanger of fire row, having a narrow range of temperature between two heat exchangers, and most of gas thermal energy is radiated in air, then directly heat radiation is drained by smoke exhaust fan, therefore, existing gas steam engine does not reclaim and makes full use of these gas thermal energies, gas thermal energy is caused to be wasted very serious, the utilization rate of gas thermal energy is low, also cause smoke exhaust fan live load large simultaneously, operating temperature is high, thus shorten the service life of smoke exhaust fan, two is that the steam moisture that existing gas steam engine steam produces is high, and the excess moisture that steam carries, can affect the mouthfeel of food, three is that existing gas steam engine steam generation is slow, steam production is not enough, vapor (steam) temperature is low, the highest can only the reaching 120 of the temperature of the steam that existing gas steam engine produces is spent more, thus cause the food of boiling hardening, become tough, and the low overlong time that also can cause boiling of vapor (steam) temperature.In sum, existing gas steam engine cannot meet that hotel, restaurant, dining room, hotel etc. are fast to the generation of steam, high-temperature, high yield, low moisture, energy-conservation high request.
Summary of the invention
A kind of steam is the object of the present invention is to provide to produce the combustion and steam generation equipment fast, vapor (steam) temperature is high, gas thermal energy utilization rate is high, energy-conservation.
The object of the present invention is achieved like this:
A kind of combustion and steam generation equipment, comprise at least two steam units, each steam unit comprises combustion chamber, fire row, and at least two heat exchangers, described heat exchanger is located in combustion chamber together with fire row, described fire row is positioned at below heat exchanger, it is characterized in that: the heat exchanger in described same steam unit is provided with cooling water inlet, another heat exchanger is provided with steam (vapor) outlet, heat exchanger in described each steam unit is connected on all successively and is provided with between the heat exchanger of cooling water inlet and the heat exchanger being provided with steam (vapor) outlet, between cooling water inlet and steam (vapor) outlet, a path is formed between each heat exchanger.
The present invention can also do following further improvement.
Described combustion and steam generation equipment comprises the first steam unit and the second steam unit, each steam unit comprises the first heat exchanger and the second heat exchanger, first heat exchanger of the first steam unit is connected mutually with the first heat exchanger of the second steam unit, first heat exchanger of the second steam unit is connected with the second heat exchanger in series, and the second heat exchanger of the first steam unit is connected mutually with the second heat exchanger of the second steam unit.The first heat exchanger preheating of running water first in each steam unit of the present invention, after the second heat exchanger heats in each steam unit, high temperature dry saturated steam is become again after preheating, thus improve the generation speed of steam, the temperature of high temperature dry saturated steam can reach 165 °.
Described cooling water inlet is connected with water inlet pipe, described inlet pipeline is provided with successively water pump, the first pressure sensor, water flow sensing unit, check-valves.Described first pressure sensor is the flow velocity for detecting water inlet in-pipe flow, and described water flow sensing unit is the flow for detecting water inlet in-pipe flow, to prevent heat exchanger dry combustion method.The import of the first heat exchanger is located at by described check-valves, thus the steam produced in the first heat exchanger can only be gone out toward the steam (vapor) outlet direction of gas steam engine, described check-valves can prevent the water in heat exchanger from causing water to reflux because steam pressure is excessive well, and all appts on guarantee inlet pipeline is not by high temperature failure.
Described top of combustion chamber is provided with exhaust outlet, and described exhaust outlet place is provided with cooling fan, and cooling fan drains hot gas, waste gas in combustion chamber rapidly, is steam engine heat radiation exhaust, normally works to enable steam engine.
Described steam (vapor) outlet is connected with steam output pipe, and described steam output pipe is provided with the second pressure sensor.Second pressure sensor is the pressure for detecting steam, in case the pressure of the steam of steam engine output is excessive.
Be arranged in combustion chamber about described first heat exchanger and the second heat exchanger.Certainly, more preferably, described first heat exchanger and the second heat exchanger setting up and down in combustion chamber, fire row is preheating first up, running water in second heat exchanger, gas thermal energy is radiation up, running water flows to the second heat exchanger with a steam unit after multiple steam unit heat, now the temperature difference of First Heat Exchanger and the second heat exchanger is large, fuel gas buring and the second heat exchanger are radiated heat energy in air and are fully absorbed by the first heat exchanger, because most of gas thermal energy is up radiation, first, the position of two heat exchangers arranges rationally, first heat exchanger radiation-absorbing above the second heat exchanger makes full use of gas thermal energy to the gas thermal energy in air, the First Heat Exchanger of each steam unit absorbs heat energy in combustion chamber internal cause and obtains preheating, take full advantage of gas thermal energy, thus improve the utilization rate of gas thermal energy, also reduce operating pressure and the operating temperature of the heat abstractors such as cooling fan simultaneously.
