Glossary Energy Information Administration (EIA)Coal gasification: The process of converting coal into gas. The basic process involves crushing coal to a powder, which is then heated in the presence of steam and oxygen to produce a gas. The gas is then refined to reduce sulfur and other impurities. The gas can be used as a fuel or processed further and concentrated into chemical or liquid fuel.
coal | National Geographic SocietyThe gases that are released during the coking process can be used as a source of power. Coal gas can be used for heat and light. Coal can also be used to produce syngas, a combination of hydrogen and carbon monoxide. Syngas can be used as a transportation fuel similar to petroleum or diesel.
CONTROLLING MERCURY EMISSIONS FROM COALFIRED .CONTROLLING MERCURY EMISSIONS FROM COALFIRED POWER PLANTS The control of mercury emissions is an important issue facing the coalfired power industry. Mercury emissions are impacted by factors including coal composition, the type of environmental control equipment installed on the unit, boiler operating conditions, and fly ash characteristics.
Retrofitting a Cleaner Future: How technology can ...In fact, retrofitting even a basic control system into coalfired power plants can reduce emissions by more than 80%. Since the control system has been well developed in the past several decades, most coalfired power plants in the US have been able to reduce SOx and particulate matter emissions by up to .
The Łagisza Power Plant: The World's First Supercritical ...The parameters of the coal and limestone to be used were analyzed extensively, which led to the design of a compact boiler m wide, 10 m deep, and 28 m high. In fact, it is only slightly larger than the boilers designed for Foster Wheeler's subcritical 235MW CFB units 1–3 at Turów power plant (22 m wide, m deep, 42 m high).
