2. PULVERISED COAL FIRED BOILER The first commercial application of pulverized coal firing for steam generation was made in the early 1920s. Since then it has become almost universal in central utility stations using coal as fuel. A pulverised coal-fired boiler is an industrial boiler used in most of the thermal power plants in operation nowadays.Learn More
utility boilers (see Table 1.1, Fig. 1.1a, and Fig. 1.1b). Figure 1.1b shows reductions for industrial boilers range from about 25 percent to 80 percent, which is a slightly higher range than for coal-fired utility boilers in Figure 1.1a. Table 1.1 shows the median reductions for industrial boilers equipped with urea-based SNCR in various industryLearn More
The most common heat transfer method for coal-fired boilers is the watertube method in which the hot combustion gases contact the outside of the heat transfer tubes, while the boiler water and steam are contained within the tubes. Coal-fired watertube boilers include pulverized coal, cyclone, stoker, fluidized bed, and handfed units.Learn More

Understanding pulverised coal, biomass and waste combustion 5 Pulverised coal firing has been the dominant technology for generating power in utility boilers for almost a century. During this period, boiler designs have evolved through an accumulating collectionLearn More
water-tube boilers also use this pulverized fuel. This technology is well developed, and there are thousands of units around the world, accounting for well over 90% of coal-fired capacity. The coal is ground (pulverised) to a fine powder, so that less than 2% is +300 micro metre (µm) and 70-75% is below 75 microns, for a bituminous coal.Learn More
