The water stored in the steam boilers allows for a much better response to changing steam demand from the plant than the single through design of a steam generator.
A coal or oil steam power plant produces electricity. Coal is the most available fuel, has a rather stable price and as a result is the most cost-effective fossil-fired technology. Nowadays, crude oil or heavy fuel oil have become quite unusual as fuels for electricity generation purposes.
The boiler in a coal-fired power plant converts chemical energy contained within the coal into heat energy that is captured and carried away in hot, high-pressure steam (Figure 3.2). Coal-burning technology has a long history and has seen many plant configurations, but the most important type of plant in modern use is the pulverized coal-fired
The greatest variation in the design of steam-electric power plants is due to the different fuel sources. Almost all coal, nuclear, geothermal, solar thermal electric power plants, waste incineration plants as well as many natural gas power plants are steam-electric. Natural gas is frequently combusted in gas turbines as well as boilers.
In today’s dynamic power generation market, plants need to be able to change load quickly to support fluctuations from non-dispatchable resources. Quite often, units and their existing automation are not designed or optimized for these operations which can prematurely wear the boiler and plant equipment from frequent thermal cycling.
