    Most coal fired power station boilers use pulverized coal. 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 pulverized to a fine powder, so that less than 2% is +300 micro meter (μm) and 70-75 % is below 75 microns, for a bituminous coal.Learn More

    While satisfactory for applications such as these, this particular definition of boiler efficiency can result in substantial errors when used for computing unit performance. Sample calculations are presented for a 600 MW coal fired unit which show errors in net unit heat rate of 1 to 3 percent due to inconsistent definitions for boiler efficiency.Learn More
