High temperature air combustion gas-burning appliance

Abstract

The invention relates to a high temperature air combustion gas-burning appliance; wherein, an inflamer (5) is a semi-closed structure, one end of an air preheater (2) is connected with an electric fan (1), the other end thereof is connected with the inflamer (5), the air preheater (2) is provided with a flue gas excess heat limit recoverer (6) which carries out heat conduction with the preheater, the flue gas excess heat limit recoverer (6) is connected with the inflamer (5) by a control valve, a thermometer of a temperature regulator (3) is connected with the air preheater (2), a control terminal of the temperature regulator (3) is connected with the control valve; a high temperature zone of the inflamer (5) is provided with a thermoelectric converter (4), an electric power output terminal of the thermoelectric converter (4) is connected with the electric fan (1). The gas-burning appliance of the invention can effectively realize energy efficiency, reduce fuel consumption, lower the discharge of carbon monoxide and oxynitride and improve the environment; furthermore, the gas-burning appliance which first heats the air and then burns the fuel can be widely applied to households or food and drink service industry.

Description

technical field [0001] The invention relates to a gas appliance, in particular to a gas appliance which burns fuel by preheating air, which can be widely used in households or catering services. Background technique [0002] The combustion method is determined by the burner. The burner is the core component of the gas stove. The research on the performance of the gas stove is concentrated on the burner part. The burner can be divided into three types: diffusion burner, atmospheric burner, and complete premixed burner. type burner. Atmospheric combustion is also called Bunsen combustion. The air it needs is obtained from the surrounding atmospheric environment by the pressure of the gas itself, and does not require other power. It is very suitable for civilian use, so the burner of general civilian gas stoves is an atmospheric burner. . Its working principle is: the gas is ejected from the nozzle at a certain flow rate under a certain pressure, and the air is sucked in from...

However, such a burner not only has low efficiency and small heat load, but also produces a large amount of carbon monoxide and nitrogen oxides, and it is difficult to meet the increasingly stringent environmental protection requirements.
