Automatic-regualting burner for gas furnace

Abstract

A gas furnace self-adjustment type burner includes shell, ejector, gas mixture chamber, combustion chamber, gas distribution hole, gas inlet and air inlet. It features linkage fan set in combustion chamber and air inlet, said linkage fan set vane a and b a and b respectively on combustion chamber and air inlet central shaft. Linkage rotation is realized by thermal current impulsion of vane whose speed depending on air inlet pressure and flow rate variation, Linkage fan rotational velocity automatically controlling fuel gas with air mixing ratio in mixing chamber, therefore having good firing effect, saving fire gases, avoiding gas mixture backfire detonation combustion, safety use etc advantages.

Description

technical field

[0001] The invention belongs to stove components, and is an automatic adjustable burner for a gas stove. Background technique

[0002] Existing gas furnace burners usually use gas and air to enter the mixing chamber from the gas source and fan through their respective air inlets. When setting the mixing ratio of gas and air in the mixing chamber, first set the gas source pressure and In the case of flow rate, the fan pressure and flow rate are selected to obtain the mixing ratio of the best combustion state. However, during the combustion process, parameters such as the amount of mixed gas required for combustion, gas pressure and flow rate, and inlet air pressure and flow rate are changed, so , the existing gas furnace burner sends air to the mixing chamber from the blower at constant pressure and constant flow, which cannot meet the needs of changes in the parameters of the combustion process; the existing gas furnace burner has poor com...
