Technical field:
The utility model relates to a full premix burner, which is mainly applicable to the field of gas appliances such as wall hanging furnace.
Background technology:
The existing wall hanging furnace premix burner includes burner shell and distributor plate.The burner shell is mainly composed of a fixed plate fixed in the mixing chamber and a fireproof orifice plate connected.The distributor board in the mixing chamber divides the mixing chamber into a primary mixing chamber and a final mixing chamber.The stainless steel plate is punched to form a fire hole.The above-mentioned burner has the following defects :(1) the combustion holes on the flame orifice plate must be densely distributed, and the diameter of combustion holes must be small, which is not convenient for punching;(2) the combustion hole cannot reach the required precision due to the processing technology;Therefore, it is not convenient to control the burner combustion load and low combustion efficiency.
The technology provides a completely premixed burner, which can not only accurately control the combustion load, effectively improve the combustion efficiency, but also facilitate processing.The technical solution is: a fully premixed burner comprises a burner shell and a fire orifice plate fixed with the furnace shell.The burner shell is mainly composed of fixed plate, bracket, distribution plate and fixed plate around mixing chamber.The fire-hole plate is made of stainless steel mesh and is installed on the downstream side of the air flow direction of the burner housing.A circular ring is selected for the fixed plate, and a mixing chamber ring is formed by the plate extending along the direction of air flow.Fixed plate can also choose rectangular ring shape, square ring or ring, according to the combustion load, product shape and other arbitrary choice, the wall of the support can arc design direction, make the appearance beautiful, play the role of drainage, distribution plate can be flat, simple processing technology.The fire hole plate is glued to the switchboard and completely covers the hole, thus effectively realizing the fixed connection between the fire hole plate and the furnace shell.The burner shell can be composed of fixed plate, and the distribution plate can be supported in one.The fire hole plate is made of stainless steel wire, and it is easy to process.Using this technology, not only can accurately control the combustion load, effectively improve the combustion efficiency, but also facilitate processing.
