Abstract

The invention relates to a porous metallic medium burner which burns the gas with low caloricity. The invention comprises a fire-proof tube, the big porous medium in the burning area, and the small porous medium in the preheating area, the burner case, the dust-cleaning metallic network or metallic brush, a pre-mixing room, and an air channel. The burning area with big porous medium and the preheating area with small porous are arranged from up to down in the burner while both of them uses high-temperature resistant stainless steel to be integrated into a whole; the fire-proof tube packs the outer wall of the upper part of air channel to the upper part of burning area; the dust-cleaning metallic network or metallic brush is arranged under the small porous medium. The invention can burn the gas fuel with the caloricity less than 1000kcal.m3 as blast furnace coal gas, to save the energy source and reduce the nitride and sulfide in the burned product to reduce the pollution. The invention can apply the industries as metallurgy and chemical plant.

Description

technical field

[0001] The invention relates to a burner used in the metallurgical industry, in particular to a porous metal medium burner for burning low calorific value gas. Background technique

[0002] At present, the metallurgical industry produces by-product gas with a calorific value below 1000 kcal, such as blast furnace gas, CO, H 2 , CnHm and other combustible components are low, and the combustion efficiency in the burner is not high, resulting in a large amount of low calorific value gas emissions, which wastes energy and pollutes the environment. As early as 1979, some scholars proposed the idea of ​​adding porous media to the burner, and many related experimental work later found that premixed combustion in porous media has many advantages: smaller lean burn limit, higher combustion rate And stability, wide range of load adjustment, high combustion intensity, small burner volume, etc., and the content of pollutants such as nitrides and sulfides in the combusti...
