In this table, calorific values for different types of coal and coal products are shown on a country by country basis. The aggregates for hard coal and brown coal are included for years prior to 1978 only. This table provides the calorific values used to convert raw tonnes of coal and coal products into energy for the OECD Coal Balance data.
Steam coal, also known as thermal coal, is suitable for electric power production. Steam coal is ground into a fine powder that burns quickly at high heat and is used in power plants to heat water in boilers that run steam turbines. It also may be used to provide space heating for homes and businesses. Energy in Coal

Abstract The operational efficiency of a coalfired boiler is strongly dependent on the type of coal fuel used for firing the boiler. The coal quality is based on its characteristics, organic, inorganic chemical composition, and heating value. This study investigates the operational effectiveness of the coalfired boiler used for steam generation operated by Sasol synfuel limited in ...

Calorific Value. The calorific value of coal is measured for almost all coal samples. It is a measure of the heating ability of a coal and is needed to estimate the amount of coal needed to produce a desired amount of heat. Calorific values are also used to define coal rank in low and mediumrank coals below the rank of mediumvolatile ...

This paper presents the thermal and economic performance of a 210 MWe coalfired power plant situated in North India. Analysis is used to predict coal consumption rate, overall thermal efficiency, mass flow rate of steam through boiler, and Net present value (NPV) of plant for given load. Thermodynamic analysis was carried out using mass and energy equations followed by empirical ...
Noun: 1. steam coal coal suitable for use under steam boilers
Steam coals for power plants must meet quality and heating characteristics of the boiler design and for the design of pollutioncontrol equipment at a power plant. Grades of steam coal are generally related to sulfur content and ash yield. Typically, the term lowsulfur coal is used for coals with less than 1 percent sulfur. In the United ...
