When heat is added to water, its temperature rises at a rate of 0.56°C (1°F) for each heat input of 2.095 kJ/kg (1 Btu/lb) If we take water at 0°C (32°F) and we add 419 kJ/kg (180 Btu/lb) then we will increase the temperature of the water by 100°C (180°F) This rise in temperature can be detected and is called Sensible Heat

Thermal power plants convert heat into power in the form of electricity. The heat is generated from a diverse range of sources, including coal, natural gas, uranium, solar energy, and geothermal energy. The heat rate (HR, kJ/kWh) of a power plant is the amount of heat input required (kJ/h) to produce one unit of electricity (kW) (see Equation 1 ...

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.

Gentle heating of coal at a temperature slightly above the boiling point of water causes a loss of weight from the sample that is defined as moisture. The moisture content of coals ranges from about 5% to almost 70%. Moisture is an undesirable constituent of coals because it reduces the heating value (water does not burn!) and its weight adds ...
