2results about How to "Improve combustion thermal efficiency" patented technology

The utility model relates to a kind of gas stove head, including fire seat and first injection pipe, first gas cavity is equipped in fire seat, first gas cavity forms lower gas layer and upper gas layer along by lower to upper distribution, the position of fire seat corresponding lower gas layer is connected with first injection pipe, first injection pipe is communicated with first gas cavity by lower gas layer, lower gas layer and upper gas layer between are equipped with the flow guide surface for guiding airflow from lower gas layer into upper gas layer, the included angle a between flow guide surface and horizontal plane is formed, 85°≤a≤90°, by optimizing the structure of flow guide surface, relative increase the inclination angle between flow guide surface and horizontal plane, mixed gas is diffused in first gas cavity at relatively slow speed under the action of flow guide surface, it is favorable to make mixed gas more fully mixed, to improve the combustion heat efficiency of equipment, reduce the carbon monoxide content generated by combustion.

The utility model provides a kind of flameless infrared radiation combustion stove, and the combustion stove includes furnace body, grate tray and heat accumulator, furnace body is equipped with annular furnace cavity, built-in spiral flow guide passage, bottom is equipped with tangential air inlet, so that combustible gas rotates flow along spiral trajectory, realizes pressure balance by centrifugal force;Grate tray is located in the upper portion of furnace cavity, is equipped with grate hole, inserts straight cylinder shape gas outlet pipe, gas outlet pipe is placed combustion nozzle;Heat accumulator is placed above grate tray, is equipped with heat storage hole corresponding with grate hole, gas outlet pipe and combustion nozzle are inserted therein, and heat accumulator absorbs combustion heat energy and converts into infrared and radiates.The stove realizes pressure balance by the rotating flow of combustible gas in spiral flow guide passage, forms flameless combustion on the upper portion of combustion nozzle after entering gas outlet pipe through grate hole.The heat accumulator converts combustion heat energy into infrared radiation, and simultaneously combines heat conduction and heat convection, efficiently transfers heat energy to the object to be heated.
