针对某铝厂热电分厂锅炉点火存在的问题,提出了用焦炉气代替轻油点火。改造的特点是：在不影响锅炉出力的情况下,节省启动费用;在低负荷下同样可以起到稳燃的作用。该厂以前的焦炉气通向大气点天灯浪费严重;焦炉气直接在大气中燃烧对环境造成很大污染。本燃烧器特点：分别在下、中二次风口布置气枪,单支枪的出力800Nm3/h;这种布置方式的好处是防止＂抢风＂。
針對某鋁廠熱電分廠鍋爐點火存在的問題,提齣瞭用焦爐氣代替輕油點火。改造的特點是：在不影響鍋爐齣力的情況下,節省啟動費用;在低負荷下同樣可以起到穩燃的作用。該廠以前的焦爐氣通嚮大氣點天燈浪費嚴重;焦爐氣直接在大氣中燃燒對環境造成很大汙染。本燃燒器特點：分彆在下、中二次風口佈置氣鎗,單支鎗的齣力800Nm3/h;這種佈置方式的好處是防止＂搶風＂。

In order to solute the question of boiler ignition in thermal electrical factory of an Aluminun plant,we substitute coke-oven gas for ligtht oil.At the same output of boiler,the cost of start up can be reduced;at low output coke-oven gas can be used to ignite with coal,and ignition is steady.Once upon a time,the coke-oven gas was ignited directly in the air,it wasted energy and caused envirnmental pollution.The characteristic of the burner is:the gas guns are placed in the lowest secondary air and the middle secondary air,the output of single gas gun is 800Nm3/h;the virtue of the burner is to prevent coke-oven gas consuming so much air for the coal.
