Most of the non-metallurgical qualities of bituminous coal are burned in central heating boilers or heating systems to acquire thermal power for producing electrical energy. Since bituminous coal is softer than anthracite, it is usually referred to as soft coal.
When a boiler is switched from bituminous to PRB coal, the furnace exit gas temperature (FEGT) must be kept 50F (average) below the PRB ash-softening temperature.
Pulverized Coal Fired Boiler Waterwall Corrosion PC-Fired Boilers generate thermal energy by burning pulverized coal that is blown by a combustion air stream to the burners in the firebox. These coal burners are typically located on the front and rear walls or in each of the corners to be known as wall fired or corner fired burners, respectively.
Fuel Calorific Value of Coal-fired Boiler 2018-05-04 08:43:50. Coal is classified into three major types namely anthracite, bituminous, and lignite. However, there is no clear demarcation between them. Coal is further classified as semi-anthracite, semi-bituminous, and sub-bituminous. Anthracite is the oldest coal from a geological perspective.
We discuss the performance impact that Adaro, an Indonesian sub-bituminous coal with high moisture content, has on opposite-wall and tangentially-fired utility boilers which were designed for bituminous coals. Numerical simulations were made with GLACIER, a computational-fluid-dynamic code, to depict combustion behavior.
• Initially Malaysia’s coal fired power stations only used Bituminous coals. • Increasing cost has lead to increasing use of lower rank coals which are cheaper and readily available. • Existing coal fired boilers can co-fire various grades of sub-bituminous coals. • Manjung 4 and TBP 4 designed for 100% lower grade sub-bituminous coals.

The No. 1 cause of furnace slagging is low furnace oxygen content. Most boilers are designed for 115% to 120% theoretical combustion air. This is generally expressed as 15% to 20% excess air. For coal furnaces, the oxygen levels would be 3% to 3.8%.
coal requiring 20% more pounds of coal could easily exceed the burning capacity of the stoker such that output of the steam generator may be reduced. In short, lower Btu coal will increase the pounds of coal to be handled and when the variations are large enough we can expect a reduction in boiler capacity. Higher Btu coal seldom gives any pro-

Coal burning, as an alternative to gas or oil burning, boilers are discussed. Burning coal needs less volume in the combustion chamber, larger furnaces, and slower gas velocities (primarily to deal with the ash). The heating value for the types of coal--anthracite, bituminous, sub-bituminous, lignite, and peat-
Bituminous coal is lower quality and easier to mine than anthracite. It is burned to produce electricity and run trains. Bituminous coal can produce excessive soot and smoke when burned, so it’s not ideal for heating, especially in coal or wood-burning stoves in the home. Bituminous coal is also used to produce coke and to make iron and steel.
slide 2 of 8. High Moisture Content . In a Boiler firing bituminous coal the maximum moisture content is in the range of 20 % . For drying this moisture around 30 % of air heated in the air heater to around 320 ° C is used. Lignites with around 45 % to 55 % moisture require much more heat to remove the moisture.
