The 170megawatt power plant at Handan Iron Steel Group Ltd's mill in Handan City, China, selected GE technology to help use emissions from iron and steel production to generate cleaner electricity. Instead of burning waste gas in a boiler, offgas from Handan's blast furnace and coke oven now power a GE 9E gas turbine to generate power.

In industrial chemistry, coal gasification is the process of producing syngas —a mixture consisting primarily of carbon monoxide (CO), hydrogen ( H2 ), carbon dioxide ( CO2 ), methane ( CH4 ), and water vapour ( H2O )—from coal and water, air and/or oxygen. Historically, coal was gasified to produce coal gas, also known as "town gas".

Coal gas, also known as a gaseous mixture, is a fuel made up of hydrogen, methane, and carbon monoxide produced by destructive distillation (continuous heating in the absence of air) of bituminous coal. Coal is mostly made up of carbon, with varying proportions of additional elements such as hydrogen, sulphur, oxygen, and nitrogen.

It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.

Coal ash. Coal ash is produced from coalfired power plants and typically contains 20 wt% of bottom ash and 80 wt% of fly ash ( Canpolat, 2011 ). The fly ash is the fines part of the ash and it is transported by flue gases. The fly ash consists of glassy spheres and is commonly used as secondary cementitious binders in Portland cement ...

Coal is an abundant natural resource that can be used as a source of energy, as a chemical source from which numerous synthetic compounds (, dyes, oils, waxes, pharmaceuticals, and pesticides) can be derived, and in the production of coke for metallurgical processes. Coal is a major source of energy in the production of electrical power ...

The utilization of coal in the cement and concrete industries takes three basic forms: (1) as a fuel in the production of cement clinker; (2) ash produced by burning coal in power stations is used as a component in cement rotary kiln feeds; (3) ash produced by burning coal in power stations is used as a mineral additive in concrete mixes.

Energy generation. For use in thermal power plants, coal is ground into dust using a device called a powdered coal mill. The resulting product, called powdered coal or pulverized coal, is then generally used in a fossil fuel power plant for electricity coal is a significant dust explosion hazard, as large quantities are suspended in air for transfer from the mill to the ...

The emissions of coal burning have been shown to be dependent on several factors,, on composition of burned coal, aftertreatment systems (such as ESP, DSP) as well as air chemistry after the emissions are released to the atmosphere (, Córdoba et al., 2012a, Córdoba et al., 2012b, Córdoba et al., 2012c, Deeds et al., 2013, Meij and ...

One of the best energy recovery options is using kiln offgas for coal mill hot gas as evaluated in Table 3. Coal mill requires 77620 Nm3/h (90670 kg/h) hot gas with temperature 248 oC to heating raw coal. Currently, about 80% coal mill offgas (72700 Nm3/h) recirculated to coal mill inlet and burner system to minimize fuel consumption.

Mine gas from abandoned mines typically contains no oxygen, and its composition changes very slowly. The methane content can range from 6080%. Even after coal mines are shut down, coal mine gas continues to be released. The composition of abandoned mine methane gas presents no technical difficulties for combustion in gas engines.

An analysis was conducted on the relationship between the calorific value of different types of coal and the theoretical air requirement. It was found that the theoretical air volume required for generating the same amount of heat during combustion is the same for different types of coal. The concept of the air/coal ratio was improved by proposing the concept of the air/carbon ratio, which ...
