Biomass gas burner

Abstract

The invention relates to a biomass gas burner. The biomass gas burner is characterized in that a long burning fire fuel gas channel, a long burning fire air channel, a main burning fuel gas channel and a main burning air channel are included; an ignition device penetrates through the long burning fire air channel and extends to the front end of the long burning fire fuel gas channel; the front portion of the long burning fire air channel, the front portion of the main burning fuel gas channel and the front portion of the main burning air channel are respectively provided with a whirlcone; the long burning fire air channel and the main burning air channel are respectively provided with a flow regulation device. According to the biomass gas burner, the long burning fire fuel gas channel and the long burning fire air channel are arranged so that a long burning fire standby function can be achieved, the consumption of liquefied gas or the consumption of natural gas is lowered, ignition burning waste is avoided, and boiler starting time is shortened; mixing of the air and biomass gas is reasonably controlled, the biomass gas can be made to be fully reacted with oxygen in a boiler, tar is burnt up, burning efficiency is improved, the tar can be prevented from being coked in the burner and the boiler, cleaning workloads are reduced, and meanwhile pollution to the environment can be reduced.

Description

technical field [0001] The invention relates to a burner, in particular to a biomass gas burner for burning biomass gas. Background technique [0002] As the fourth largest energy source in the world, biomass energy accounts for about 14% of the total global energy consumption. Biomass energy has a wide range of sources, high volatile content, low ash content, and low sulfur content. Due to the growth environment absorbing CO 2 The amount is equivalent to the CO emitted by combustion 2 amount, so CO is realized in the energy conversion process 2 The net emission is close to zero, which is conducive to improving the greenhouse effect. It is of great significance to research and develop technologies for efficient utilization of biomass energy, to save conventional fossil energy, and to optimize the energy structure. Biomass gas is a combustible gas produced by gasification furnaces of crop straw and forestry waste. It is a way for the development of biomass energy to la...

Problems solved by technology

[0003] Due to the characteristics of biomass gas itself, it is not easy to ignite biomass gas directly with electric sparks. At present, general biomass gas burners are ignited by liquefied petroleum gas or natural gas ignition guns, and a certain amount of liquefied petroleum gas is consumed every time the burner is started. or natural gas, and a series of safety procedures such as valve leak detection are required before each start-up, which is time-consuming and labor-intensive, and the economic benefits are not good

In addition, due to the generally high tar content of biomass gas, it cannot be fully cracked, and the combustion in the existing burner is insufficient, resulting in reduced combustion efficiency and easy to cause environmental pollution; at the same time, the resistance of the burner channel is slightly larger, which will cause tar. Builds up quickly, tends to cause tar to clog burners, and is very difficult to clean
