Problems solved by technology
The forced-air infrared combustion adopts the form of heat radiation, which can catalyze combustion, but the combustion is unstable; the natural-induced-air diffusion combustion adopts the heat transfer form of heat convection. Although the combustion stability is good, the heat generated Low, generally lower than 800°C, low combustion efficiency

The invention relates to a negative-pressure infrared combusting device which comprises a combustor, a water storage chamber and a draught fan. The upper end of the interior of the water storage chamber is provided with a combusting chamber. The upper end of the combusting chamber is provided with the chamber, the lower end is communicated with an entry of the exterior draught fan through a fume passage, and the interior is provided with an electronic high-pressure igniting needle which is communicated with the exterior of the water storage chamber. The device is characterized in that the combustor consists of an air inlet elbow, an air door, a gas spray nozzle, an ejector, a mixing cavity, an infrared ray combusting ceramic plate and an outer casing; and the air door is arranged on the gas spray nozzle. The invention has the advantages that the combustor is arranged at the upper end of the water storage chamber, the negative-pressure combustion type is used, the flame type is flameless combustion of the infrared ray ceramic plate, the fume exhaust type is forced fume exhaust, the combustion type is complete combustion, and the air inlet type is negative-pressure air suction, therefore, the combustion is sufficient and the heat exchange efficiency is high.
Description
technical field [0001] The invention relates to a combustion device, in particular to a negative pressure infrared combustion device. Background technique [0002] The combustion devices of the existing wall-hung boilers are generally forced-induced-air infrared combustion and natural-induced-air diffused combustion. The forced-air infrared combustion adopts the form of heat radiation, which can catalyze combustion, but the combustion is unstable; the natural-induced-air diffusion combustion adopts the heat transfer form of heat convection. Although the combustion stability is good, the heat generated On the low side, generally lower than 800°C, the combustion efficiency is low. Contents of the invention [0003] In order to overcome the defects of the prior art, the invention provides a negative pressure infrared combustion device with stable combustion, complete combustion and catalytic combustion capable of generating high heat. The technical scheme of the present inv...
