Mineral contentCoal contains a variety of minerals in varying proportions that, when the coal is burned, are transformed into ash. The amount and nature of the ash and its behaviour at high temperatures affect the design and type of ashhandling system employed in coalutilization plants. At high temperatures, coal ash becomes sticky (, sinters) and eventually forms molten slag.
Ash handling equipment is one of the most crucial links in the solid fuel, biomass boiler, and combustion systems chain. Found in plants around the world, ash handling systems are set up in harsh environments where they endure intense temperatures.
Layout of Ash handling system . Ash Handling System: Boilers burning pulverized coal (PC) have bottom furnaces. The large ash particles are collected under the furnace in a waterfilled ash hopper, Fly ash is collected in dust collectors with either an electrostatic precipitator or a baghouse.
A coalfired power station or coal power plant is a thermal power station which burns coal to generate power stations generate over a third of the world''s electricity but cause hundreds of thousands of early deaths each year, mainly from air pollution.. A coalfired power station is a type of fossil fuel power coal is usually pulverized and then burned in a ...
Ash handling systems may employ different forms of pneumatic ash conveying or mechanical ash conveyors. A typical ash handling system may employ vacuum pneumatic ash collection with ash conveying from several ash pick up stations and resulting in delivery to an ash storage silo for interim holding prior to load out for disposal or reuse.

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called 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.

Types. FBC systems fit into essentially two major groups, atmospheric systems (FBC) and pressurized systems (PFBC), and two minor subgroups, bubbling (BFB) and circulating fluidized bed ().Fluidized Bed Combustible. Atmospheric fluidized beds use limestone or dolomite to capture sulfur released by the combustion of coal.
An integrated gasification combined cycle (IGCC) is a technology that uses a high pressure gasifier to turn coal and other carbon based fuels into pressurized gas—synthesis gas ().It can then remove impurities from the syngas prior to the power generation cycle. Some of these pollutants, such as sulfur, can be turned into reusable byproducts through the Claus process.
