Description
Technical field
The present invention relates to the combustion control equipment field, be specially a kind of single control multi-port compound jet and expand temperature field accent flame burner nozzle.
Background technology
Burner is used for the heat supply structure of Thermal Equipment, and its performance has directly determined crudy, the effects of energy saving and emission reduction of equipment integral body, is most crucial Thermal Equipment unit.The burner and the supporting adjusting control module thereof of one cover excellent performance need possess following characteristic usually: the temperature field distributed uniform, that regulates is highly sensitive, regulate ratio and burn-off rate height, the low NOx ratio, simple in structure and be convenient to safeguard etc., mainly realize by following dual mode at present: first kind is many burners, small-power configuration mode, as shown in Figure 1, adopt the low power burner 1 of intensive layout to realize the even layout of fire box temperature field, each burner 1 all connects an airflow pipe 2 and a fuel gas transportation pipeline 3.This is current domestic more general technology, and along with the application of pulse-combustion and other zonule control technology, the cost pressure of this technology is day by day heavy, simultaneously because of its take up room bigger, be subjected to Thermal Equipment the overall structure restriction this The Application of Technology.Second kind is by changing the expansion burning that the spout moulding realizes independent control burner, as shown in Figure 2, having outer ring pinkeye 11 and inner ring pinkeye 12 on the flame jet of burner 1.This method has realized effect that traditional burner temperature field is expanded in comparatively simple mode, but the amplitude of implementing the expansion burning is narrower, lower, the regional flame burn-off rate of adjusting is low etc., therefore can not realize adaptability preferably to most of non-specified fired states.
Summary of the invention
In order to overcome the defective of prior art, a kind of combustion control equipment that can widen ignition temperature field and adjusting function, contaminant restraining discharging, optimize temperature homogeneity is provided, the invention discloses a kind of single control multi-port compound jet expansion temperature field and transfer flame burner nozzle.
The present invention reaches goal of the invention by following technical solution:
A kind of single control multi-port compound jet is expanded the temperature field and is transferred flame burner nozzle, comprise burner, airflow pipe, fuel gas transportation pipeline, orifice plate, flow control valve, stop valve and air control valve, it is characterized in that: each burner all includes the spout more than 2 or 2, airflow pipe and fuel gas transportation pipeline all with being connected of burner, each burner connects an airflow pipe and a fuel gas transportation pipeline, each bar airflow pipe all passes through an air control valve and is connected with the spout of 2 or 2 above burners simultaneously, all be in series with orifice plate on airflow pipe and the fuel gas transportation pipeline successively, flow control valve and stop valve, air enter the spout of burner successively by airflow pipe and air control valve.
Described single control multi-port compound jet is expanded the temperature field and is transferred flame burner nozzle, it is characterized in that: each burner all includes 2～5 spouts, each bar airflow pipe all passes through an air control valve and is connected with the spout of 2～5 burners simultaneously, spout is evenly distributed with linear fashion in burner, two at this moment adjacent spouts are under the control of air control valve, perhaps all spray long flame, perhaps all spray short flame, perhaps one is sprayed long flame and the short flame of another injection.Spout also can be arranged in rectangle in burner.
Described single control multi-port compound jet is expanded the temperature field and is transferred flame burner nozzle, it is characterized in that: orifice plate adopts that differential pressure is artificial, in automatic detection device and the pressure-detecting device any one, and flow control valve and stop valve all adopt any one in butterfly valve, gate valve, diaphragm valve, plug valve and the ball valve.
The present invention has changed traditional independent regulation and control nozzle method, also discarded and changed the method that the spout moulding realizes expanding the temperature field, and the burner that adopts the corresponding many shower nozzles of a cover regulation and control system to burn, single burner ability evenly is decomposed into two spout ability outputs, each spout is arranged in parallel staggered by the phase angle of secondary wind adjusting order, realize that parallel between spout, cross-current switches, and guarantees the region-wide temperature distribution homogenization of burning, and reduces to pollutant generation level lower.
Adopt the present invention, air distributes through air one secondary air adjustor valve 24 before entering spout, can realize compound jet by regulating adjacent burner lip jet mode simultaneously, and concrete steps are as follows:
When adjacent spout all was long flame, the spout flow field was relatively independent, constituted the typical ignition temperature field of expanding jointly; When spout all was weak point flame, the flow field constituted typical flame root area and concentrates the temperature field that discharges in spout root area juxtaposition; Adjacent 1 spout is long flame, 1 spout is short flame in addition, and two kinds of flame forms were both interfered mutually, and the original separately form of reserve part has weak reaction zone compensate function simultaneously, constitutes typical interdigitated flow field.
At different Thermal Equipment temperature field requirements, determine effective jet compound mode, can make more uniformity of burning bulk temperature field, and avoid the concentrated combustion of fuel, reduce NO
xGrowing amount.
The present invention is divided into 2 or 4 parts with the live load of single burner of tradition, and requires to rearrange each spout according to the temperature field distribution of Thermal Equipment, realizes the expansion of bulk temperature field.The present invention can be applicable to pulse or ratio combustion control mode.
The present invention has changed traditional independent regulation and control nozzle method, also discarded and changed the method that the spout moulding realizes expanding the temperature field, and the burner that adopts the corresponding multi-port of a cover regulation and control system to burn, single burner ability is decomposed into the output of multi-port ability, each spout makes up layout according to demand, and to regulate each spout sequential phase angle by a secondary wind staggered, realize that compound jet switches between spout, guarantee the region-wide temperature distribution homogenization of burning, and reduce to pollutant generation level lower.
The invention has the beneficial effects as follows:
1. the equitemperature field distribution in burner cross section can arbitrarily change by the mode of adjusting each spout layout according to Thermal Equipment function needs;
2. the burner burn-off rate transfers the flame burner nozzle performance consistent with adjusting ratio and cylindric single channel;
3. utilize the compound jet control technology, realized 3 kinds of flame and temperature field forms that remarkable difference is arranged, and 3 kinds of forms can realize dynamic adjustments at each burner spout;
4. utilize the compound jet dynamic control technology, realize that the relative conventional art better uniformity of distribution in temperature field and the more effective polluter of burner integral body generates control;
5. compare tradition and divide control equipment to reduce cost more than 40%, and the temperature field is expanded and the burning organizational capacity is much better than traditional burner that adopts the spout moulding to realize expanding burning.
