The utility model relates to a multi-channel gas hot-blast stove, which comprises a furnace body, an air distribution fan and a burner. The bottom of the furnace body is connected with an air distribution fan, and the burner is fixed and installed inside the furnace body. The burner includes a main pipe, and a number of branch pipes are arranged and installed in array on the main pipe. Nozzles are arranged directly above each branch pipe, and both sides of each nozzle are installed on the inclined air intake plate. The two ends of the air inlet orifice plate are fixed on the furnace body through the orifice plate fixing plate. The utility model has a multi-channel burner installed in the body of the hot blast stove, and the gas enters each branch gas pipe by the main gas pipe, and is discharged into each nozzle by the outlet hole at the top of each branch gas pipe. The gas is ejected from each nozzle to form a number of small pillars for combustion. The hot blast stove replaces the traditional large pillars with small pillars, which can make the gas burn more fully and reduce the temperature of the combustion zone, thereby, the combustion zone can be reduced. Ultra-low nitrogen combustion technology has been realized.
【技术实现步骤摘要】
一种多通道燃气热风炉
本技术涉及燃气热风炉领域,具体涉及一种多通道燃气热风炉。
技术介绍
现有的燃气热风炉中,燃烧器一般只有一个喷嘴,工作时,喷嘴喷出一个大的火焰,导致炉体内温度非常高,炉体寿命下降,而且,燃气燃烧不充分,导致烟气中氮氧化物含量较高,同时,大的火焰所需的炉体体积大,占地面积大。
技术实现思路
本技术的目的在于提供一种多通道燃气热风炉,用以解决现有技术中的燃气热风炉火焰大,导致炉体寿命短、氮氧化物含量较高的问题。本技术提供了一种多通道燃气热风炉,包括炉体、配风风机和燃烧器,所述炉体底部侧面设置进气口,该进气口连接配风风机,所述燃烧器固定安装在炉体内部,所述燃烧器包括主气管,该主气管与外部供气装置连接,所述主气管上呈阵列式布设安装若干分支气管,所述每个分支气管正上方均设置喷嘴,所述每个喷嘴两侧安装在倾斜的进风孔板上,喷嘴两侧的进风孔板形成类倒“八”字形结构,所述进风孔板上密布若干小孔,所述进风孔板两端通过孔板固定板固定在炉体上。进一步的,所述燃烧器的外围还设置调风阀板,该调风阀板安装在炉体上。进一步的,所述炉体包括两层保温封板和固定于该两层保温封板之间的保温层 ...
