A Research on Ignition of a Boiler by Using Coke-Oven Gas Instead of Light Oil and Alternation of the Boiler

Article Preview

Abstract:

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