The basic function of the power plant is to convert energy in coal to electricity. Therefore, the first thing we should know is how much energy there is in coal. Energy content of coal is given in terms of KiloJoules (kJ) per Kilogram (kg) of coal as the Gross calorific value (GCV) or the Higher Heating value (HHV) of coal.
A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
The pulverized coal is concentrated and uniformly supplied by the milling factory, with stable coal quality. Pulverized coal combustion is sufficient, boiler heat transfer effect is good, air excess coefficient is small, and system thermal efficiency is high; power consumption equipment with large power is equipped with frequency converter, and the power saving effect is obvious.
