    Fly ash or flue ash also known as pulverised fuel ash in the United Kingdom is a coal combustion product that is composed of the particulates fine particles of burned fuel that are driven out of coal fired boilers together with the flue gasAsh that falls to the bottom of the boiler is called bottom ashIn modern coal fired power plants fly ash is generally captured by electrostatic parameters has been discussed The maximum amount of coal for pulverizing with raw mix was found to be 10 of the raw mix as calculated from the calorific value and the heat of clinkerization of coal The coal residue left after burning was utilized in the cement raw material for which a

  • as a supplemental fuel to coal Only one California plant utilizes gas as a primary kiln fuel This is a relatively small plant that produces white cement The remainder of the natural gas usage is associated with boiler and machine drive end us Figure 2 1 Cement Industry End Use Electricity Consumption Process Machine Drive 81 Process GCC of America Inc is a regional manufacturer of cement concrete and coal Grupo Cementos de Chihuahua GCC created the US division with the purchase of a 500 000 ton cement manufacturing facility in Tijeras NM A distribution terminal in Albuquerque and another in El Paso were added later in the same year

  • Cement manufacturing is highly energy and emissions intensive because of the extreme heat required to produce it Producing a ton of cement requires 47 million BTU of energy equivalent to about 400 pounds of coal and generates nearly a ton of CO 2 Given its high emissions and critical importance to society cement is an obvious place to Cleaner Power Plants On this page Power Plants EPA finalized the first national standards to reduce mercury and other toxic air pollution from coal and oil fired power plants In addition mercury standards for industries such as cement production steel manufacturing and many others have reduced mercury emissions from these

  • Coal derived coke was the fuel used in most static kilns and so was the dominant fuel in the cement industry in the nineteenth century Coal could not be used in static kilns in which the fuel is fed in with the raw material mainly because during the gradual heat up of the charge the fuel s volatiles are lost without ignition so wasting up Cement Plants Coal Coal is the fuel that undergoes least human intervention before use it is burned in essentially the same condition in which it is dug from the ground Because of
