The invention discloses a biomass gas burning system which comprises a plurality of burning devices arranged in a heating furnace and a gas pipeline for conveying biomass gas, wherein the burning devices are respectively arranged on furnace walls of the discharge end surface and two side surfaces of the heating furnace, the gas pipeline comprises a main gas pipe and branched gas pipes, the gas inlet of the main gas pipe is arranged above the tail of the heating furnace, and the burning devices are communicated with the main gas pipe through the branched gas pipes. The main gas pipe of the invention conveys the biomass gas into the burning devices distributed on the end surface of the tail of the heating furnace and at the two sides of the heating furnace through the branched gas pipes; because the biomass gas is conveyed from top to bottom, the biomass gas can be uniformly distributed into the burning devices; and simultaneously, the burning devices on the furnace walls are alternately arranged from top to bottom, thereby ensuring the uniformity of the temperature in the heating furnace and being favorable for improving the burning efficiency of the biomass gas.
Description
technical field [0001] The invention relates to a heating furnace combustion system, in particular to a heating furnace combustion system using biomass gas as fuel. Background technique [0002] Biomass gasification technology is a relatively mature technology. Biomass gasification refers to processing biomass raw materials (woody biomass used in this project) and sending them into the gasifier. Gasification and cracking are carried out to obtain combustible biomass gas. The biomass gas energy can be applied to facilities such as heating furnaces and generating sets. [0003] For example, Chinese patent ZL200820032942 discloses a heating furnace combustion system, which includes multiple pairs of regenerative left and right side burners, and multiple pairs of regenerative left and right burners are installed on both sides of the heating furnace roof. The regenerative left burner is connected to the smoke main pipe and the air main pipe through the left reversing valve, and...
