The utility model is blown in burner by blower fan, air quantity is adjustable, when being speed-changing draught fan, blower fan controls air quantity by controlling rotation speed of fan, when being single speed blower fan, blower fan controls air quantity by air quantity adjusting mechanism, combustion gas first enters burner through venturi mixer again by gas electromagnetic valve, the variation of air quantity produces the variation of flow velocity in venturi, make the air pressure change at the fuel gas inlet place of venturi mixer, gas electromagnetic valve valve port open amount changes thereupon, like this, greatly improve the mixed proportion of gas quantity and air capacity, send to after burner, through ignition electrode high-tension igniton, realize combustion gas and air mixed combustion.
When volume adjusting apparatus of the present utility model is air door assembly, twisting handle, fork swings around fulcrum B, and air door rotates around fulcrum A, realizes and changes air port size, changes the object of air quantity; Maximum, the minimum zone of handle immobilize, and define maximum, the minimal openings amount in air port; Because the calorific value of different regions combustion gas is different with air pressure, required maximum, minimum air quantity difference; By mobile pole, adjust and change B point position, change maximum, the minimal openings amount in air port.
The utility model compared with prior art tool has the following advantages:
1, before burning, combustion gas and air reach desirable mixing match (full premix), during burning, do not need extraneous air, the flame propagation speed of full premix combustion, combustion volume calorific intensity is very high, and can be in very little excess air coefficient α=1.05-1.1 time burning, there is hardly chemically incomplete combustion phenomenon, greatly improve the thermal efficiency;
2, can effectively reduce the discharge of pollutant, reach full premix combustion and greatly reduce generation fuel NO and prompt NO, reduced temperature mode nitrogen oxide, owing to having completed combustion gas before burning, mix with the even of excess air, can guarantee to a great extent that each combustion gas molecule has sufficient oxygen molecule to exist around, therefore, the CO concentration of emission of full premix combustion is very low;
3, can realize air quantity and regulate, be convenient to adjust according to actual needs ignition temperature, reduce combustible loss;
4, save mass energy, reduce burning cost, extend the service life of cooking stove.
