Background technology
Blast furnace gas is the byproduct that produces in the ironmaking processes, directly enters atmosphere and pollutes the environment.Along with the enhancing of a lot of industry energy conservation environmental consciousnesses, a lot of enterprises utilize blast furnace gas to generate electricity.But because blast furnace gas calorific value is low, can't directly light with the high-voltage pulse igniter, general enterprise adopts natural gas, coal diesel oil to burn medium as the companion, and these companions burn media and lighted the back as the altar lamp blast furnace gas that ignites by the high-voltage pulse igniter.They have a common ground namely: use other high heating value medium to accompany burning, light companion's burning device and refire blast furnace gas, wasted resource so greatly, increased production cost.
Blast furnace gas generating combustion system benefit originally: used the natural gas companion to burn the consumption of fuel gas originally: domestic certain steel mill's blast furnace gas electricity generation system adopts the natural gas companion to burn, and actual gas consumption is: 3500000M
3/ month x12 the month=42000000 M
3/ year, be worth: 42000000 M
3/ year x2.5 unit/M
3=1.05 hundred million yuan/year (Gas Prices is by 2.5 yuan/M
3Calculate)
