Steam Generation - an overview | ScienceDirect Topics
Steam generation in a pulverized coal-fired boiler is accomplished in a configuration of thermal-steam/water sections, which preheat and evaporate water, and superheat and reheat steam. An example of a coal-fired utility boiler is shown in Fig. 4.4 (the fundamentals of steam production and energy flow were discussed in Chapter 4).
Steam and Condensate - A basic overview of a steam system - The Boiler House
Steam boilers are usually operated under pressure, so that more steam can be produced by a smaller boiler and transferred to the point of use using small bore pipework. When required, the steam pressure is reduced at the point of use.
