Blast furnace gas (BFG) is a by-product of blast furnaces that is generated when the iron ore is reduced with coke to metallic iron.It has a very low heating value, about 93 BTU/cubic foot (3.5 MJ/m 3), because it consists of about 60 percent nitrogen and 18-20% carbon dioxide, which are not flammable.
Keywords: Waste Heat Recovery, Slag, Granulation, Particles, Gravity Bed Boiler . Introduction . Blast furnace slag is one kind of solid waste, which is discharged from blast furnace. And the temperature of molten slag ranges from 1450 to 1650 ºC. In 2014, the output of blast furnace iron was more than 0.71
At present, blast furnace gas has become an important source of energy to be used in the metallurgical industry with the development of technology about blast furnace gas boiler , checker chamber combustion, combustible gas enrichment and air/gas dual preheating.

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.
Finding the right boiler for your home can be the difference between a cozy winter and a freezing house. Armed with our buyer's guide, expert support and customer reviews, you can feel confident in finding the right boiler for your needs.
Coke Oven Boiler Industry - casapepa1.de. coke oven gas boiler - natuurmonumentdebeer.nl. Coke Oven Gas Fired Boiler--ZBG. During the smelting process and coking manufacturing, coke oven gas is generated, and the by-product gas can be recycled as fuel for boiler to generate energy for the coking, smelting, iron making industry.
The tranditional thermal calculation program cannot satisfactorily reflect the variety steam temperature characteristics of boiler burning mixture of pulverized coal and blast furnace gas(BFG). In order to resolve this problem, the method of combining experimental study and thermal calculation is adopted.
Boiler furnace tasks The most important task of the boiler furnace is to provide conditions for proper combustion of fuel which is achivedby: 1. Fuel supply of the boiler furnace at the required rate and keeping it in the furnace by the time sufficient for burnt out. 2. Air supply of the boiler furnace at the required rate and

joint and separate combustion of blast-furnace gas and diesel oil under the conditions of randomly changed flow rates of blast-furnace and diesel is considered. Key Words: Blast Furnace Gas, Boiler, efficiency, etc. 1. INTRODUCTION: Steam generation system or boiler is used for changing
Blast Furnace Gas Blast furnace gas is a by-product of blast furnaces where iron ore is reduced with coke into metallic (pig) iron. The gas has a very low heating value of around 0.9kWh/Nm 3 , which on its own is typically not high enough for combustion in a gas engine.
This is the type of boiler used in nearly all steam locomotives. The heat source is inside a furnace or firebox that has to be kept permanently surrounded by the water in order to maintain the temperature of the heating surface below the boiling point. The furnace can be situated at one end of a fire-tube which lengthens the path of the hot
A blast furnace operates at about 2,800 degrees. It is the first step in removing impurities and producing steel from iron ore. Pig iron that is produced in a blast furnace is taken to a basic oxygen furnace, and then refined into a higher grade of steel. Morris said dismantling the old furnace was probably the most complex aspect of the project.
PowerBlast blast furnace gas boilers are customized for the combustion of blast furnace gas, coke oven gas, and LD converter gas. The units are available in modern bottom supported single-drum design for smaller units, or El Paso (radiant boiler) design for larger units.
APPLICABILITY. 40 CFR 63.11193 to 63.11196. The boiler MACT standard for area sources establishes emissions limitations and work practice standards governing HAP emissions from the following units located at sources that have the potential to emit HAPs at levels below major source thresholds (i.e., those with the potential to emit less than 10 tpy of an individual HAP or less than 25 tpy of a
In the steel industry, the recovered waste blast furnace gas (BFG) was mixed with natural gas as an alternative fuel to curb the consumption of the natural gas . It was found that if 50% of the waste BFG that contained 28% carbon monoxide, and 72% nitrogen was mixed with natural gas, the natural gas consumption decreased by 2%.
