Blast Furnace Gas Boiler Suppliers
Blast furnace gas (BF gas) is a byproduct gas produced during the production of hot metal (liquid iron) in a blast furnace, where iron ore is reduced with coke to produce hot metal. The blast furnace gas which comes out from the top of the blast furnace is at a high pressure (usually 1.5 atm to 2.5 atm in modern blast furnaces) and normally at a temperature of around 100 deg C to 150 deg C. When there are abnormalities in the burden descent then this temperature can be higher. A typical blast furnace produces 1200 – 2000 N cum of BF gas per ton of hot metal. The energy content of this gas may equal to an energy export of around 1.2 M cal/ton (5GJ/ton) of hot metal, or approximately 30 % of the gross energy consumption in the blast furnace. This energy content can be utilized by recovering, cleaning, and storing the BF gas and using it as a fuel gas in the steel plant or in the boilers for the production of steam for the electricity generation.

ZBG blast furnace gas boiler advantages
The blast furnace gas boiler adopts “Π” type layout, front suspening back supporting, the plumping system, and superheater are suspended in the boiler roof, economizer and air preheater are set at the rear of steel frame, and the air preheater can be pulled out from the boiler rear, easy for maintenance and inspection.
Burners are arranged in the four corners, using vortex burners to ignite the four corners. Higher air temperature can meet the requirement of coal gas firing temperature and aerodynamic conditions, ensuring fuel gas fully burning.
In addition to the normal protection device, the boiler is equipped with automatic ignition device, flame monitoring device, flame-out protection device, and automatically cut-off gas supply device when coke gas pressure is below a certain value.
