Next we consider the development of a steady-state performance model, such as might be used in optimizing the operating conditions of an electrical power generator (see Chapter 19). 

A furnace is a device (enclosure) for generating controlled heat with the objective of performing work. In fossil-fuel furnaces, the work appHcation may be direct (eg, rotary kilns) or indirect (eg, plants for electric power generation). The furnace chamber is either cooled (waterwaH enclosure) or not cooled (refractory lining). In this article, furnaces related to metallurgy such as blast furnaces ate excluded because they ate coveted under associated topics (see... 

Electric Power Generation. Hydrothermal steam and hot water resources having temperatures ia excess of about 150°C are generaHy suitable for the production of electricity (see Eig. 3a). Because electricity is easy to market and transport, it is the only product of hydrothermal energy which permits the resource to be utilized at some distance from its actual location. 

Combustion. Most of the mined coal is burned to produce steam for electric power generation (qv). The calorific value determines the amount of steam that can be generated. However, the design and operation of a boiler requires consideration of a number of other properties (see Furnaces, FUEL-FIRED). 

Electric Power Generation. Coal is the primary fuel for thermal electric power generation. Since 1940 the quantity of bituminous coal consumed by electric utilities has grown substantially in each successive decade, and this growth is expected to continue for many years. Coal consumed by electric utilities increased from about 536 x 10 t in 1981 to 689 x 10 t in 1989 (2). The reasons for increased coal demand include availability, relative stability of decreasing coal prices, and lack of problems with spent fuel disposal as experienced in nuclear power plants (see Nuclearreactors). 

Tall stacks are no longer considered to be an acceptable alternative for controlling emissions from electric power generating plants. (See further discussion in Chapter 26, Section V.)...
