Abstract

The invention provides a single-layer porous medium combustor. The single-layer porous medium combustor comprises an air inlet pipe, a fuel gas inlet pipe, a premixing chamber and a pre-combustion chamber. The air inlet pipe is arranged on the upper portion of the premixing chamber, the fuel gas inlet pipe is arranged on the side wall of the premixing chamber, and gas introduced into the air inlet pipe and gas introduced into the fuel gas inlet pipe are mixed in the premixing chamber; the pre-mixing chamber is fixedly connected with the pre-combustion chamber, and mixed gas in the pre-mixing chamber is introduced into the pre-combustion chamber.

Description

technical field [0001] The invention relates to the field of burners, in particular to a single-layer porous medium burner. Background technique [0002] With the rapid development of China's economy, energy and environmental issues have increasingly become the focus of people's attention. my country is facing a series of problems such as the prominent contradiction between energy supply and demand, the increasingly serious environmental pollution and the continuous destruction of ecology. Therefore, various low calorific value gases have been developed to make combustion more efficient and clean. Conventional combustion technology cannot meet low pollutant emissions, but porous media combustion technology integrates energy saving, emission reduction and environmental protection. [0003] The traditional single-layer porous media burner is not conducive to the flame doomed in the porous media, and the combustion is incomplete and unstable. In addition, the phenomenon of t...
