Read MoreSteam 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).
Read MoreThe potential for energy saving depends on the type of boiler installed and the fuel used. For a typically older model shell boiler, with a flue gas exit temperature of 260 o C, an economizer could be used to reduce it to 200 o C, increasing the feed water temperature by 15 o C. Increase in overall thermal efficiency would be in the order of 3%.
