Abstract

The invention relates to a metallic fiber and multi-hole ceramic dielectricsurface burner, belonging to heat energy engineering technology area. The burner comprises burner shell, gas pipeline and air pipeline. In the empty cavity constituted by the burner shell, metallic fiber medium in combustion zone and ceramic medium in preheat zone are set from upper to lower in turn and two medium are tightened together. The material of metallic fiber medium in combustion zone is made of Fe-Cr-Al alloy and the material of ceramic medium in preheat zone is made of zirconia or silicon carbide. Compared with ordinary surface burner, the invention can prevent tempering effectively, improve the adjustable range of fuel and air and improve burning temperature in certain range so as to improve thermal efficiency. The burner in invention can burn natural gas, liquefied petroleum gas and mixed gas so on, also burn air fuel with low thermal value which is approached to 1000kcal / m3.

Description

technical field [0001] The invention belongs to the technical field of thermal energy engineering, relates to a burner for production and living, in particular to a metal fiber-porous ceramic medium surface burner. Background technique [0002] At present, by-product gas with calorific value less than 1000 kcal in industrial production, such as blast furnace gas, in which CO, H 2 , C n h m The content of combustible components is low, and the combustion efficiency in the burner is not high, resulting in a large amount of low calorific value gas discharge, which wastes energy and pollutes the environment. As early as 1979, some scholars proposed the idea of ​​adding porous media to the burner. Afterwards, many related experimental works also found that premixed combustion in porous media has many advantages: larger lean burn limit, higher combustion rate And stability, wide range of load adjustment, high combustion intensity, small burner volume, etc., and the content of p...
