1/11/2014 · Use of coal with biomass as a supplementary fuel in the combustion or gasification based processes is a viable technological option for reducing the harmful emissions. Co-combustion of coal with biomass for electricity generation is gradually gaining ground in spite of the fact that their combustion behavior differ widely due to wide variations in their physical and chemical properties.

Coal–biomass co-combustion: An overview - ScienceDirect

The primary aim of combustion is to obtain maximum amount of steam from each unit of fuel. But impurities in fuels and operational problems are limitations to achieve maximum output from burned fuel. The impurities in coal can lead to formation of slag in boiler furnace, can leave the clinkers on the fuel bed and the presence of Sulphur can lead to

The Role of Coal Characteristics in Boiler Operation

The 2% lower limit, of course, is anthracite coal. This coal characteristic directly effects the combustibility of the pulverizer product. With lower volatile content, the required fineness increases. For medium volatile coals, it is usual to pulverize the fuel such that 70% will pass a 200 mesh screen.

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Fuel flow control. The primary boiler fuels are coal, oil, and gas. Oil and gas involve the simplest controls, since they can be measured easily and flow is regulated by a control valve in the fuel line. On the other hand, since coal is an unmeasured fuel, the control system is open-loop, in which a fuel demand signal positions a coal-feeding
