Abstract

The invention relates to a gas fuel catalyst burner, which can be used to heat system. Wherein, the pre-mixing room (1) has a air guide tube (2) and a cyclone guide surface (3) to mix the fuel gas and the air uniformly; the catalyst burning room is formed by two catalyst burning rooms as fuel-rich area and fuel-lack area; the second fuel or air mixing room (10) is arranged between two catalyst burning rooms, which comprises four tangential fuel gas or air nozzles (11) to form the cyclone to mix the secondary fuel gas and air and fuel gas uniformly; and a metallic porous plate (4) is between the pre-mixing room and the first catalyst burning room to avoid backfire. The invention can realize high efficiency and lower discharge.

Description

technical field

[0001] The invention relates to a catalytic burner used for heating or heating (hot air) system, the fuel of which is natural gas, coal gas or liquefied petroleum gas, belonging to the field of energy utilization. Background technique

[0002] Gas combustion methods include diffusion combustion and premixed combustion, both of which are flame combustion. Modern scientific research has proved that flame combustion has two fatal shortcomings: (1) Flame combustion is an oxidation reaction of burning substances with the participation of free radicals, which involves the gas phase initiation of free radicals (especially oxygen free radicals), which inevitably generates Part of the electronically excited state product releases energy in the form of visible light. This part of energy cannot be used and lost, resulting in low energy utilization. (2) The gas-phase initiation of free radicals causes nitrogen in the air to participate in the combustion reaction to for...
