Why Pulverized Coal is Used in a Power Plant

Coal for Power Plants. The coal fired power plant converts energy in coal to electricity. The basic input into the system is the fuel that is coal. All other systems and equipment only aid in this conversion process. Before going into the details, let us look at the quantity of coal processed in a power plant.Advanced Pulverized Coal Combustion,development of the Low Emission Boiler System (LEBS), a highly advanced pulverized coal-fired power plant, and High Performance Power Systems (HIPPS), highly efficient systems based on the indirectly fired combined cycle.Pulverized coal-fired boiler - Wikipedia,A pulverized coal-fired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.

the efficiency of existing coal fired plants. Operation of non-optimized boiler can lead to reduced boiler efficiency, increased excess air requirements, delayed combustion, increased heat loss, high CO and NOx emissions and many other. Optimization of combustion in pulverized coal fired boiler is very important today for every thermalPulverized Coal Firing main purpose before entering,thermal power plants Advantages of using pulverised coal 1) A wide variety of low grade fuels (coal) can be used and burnt easily. 2) Greater surface area is exposed for combustion and hence combustion is faster and efficient.Boiler and Its Tangential Fuel Firing System,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. This system has many advantages such as ability to fire varying quality of coal, quick responses to changes in load, use of high pre-heat air temperatures etc.

Pulverised Coal Combustion with higher efficiency,

In conventional coal-fired plants coal is first pulverised into a fine powder and then combusted at temperatures of between 1300 and 1700 o C. This process heats water in tubes in the boiler so that it becomes steam at a pressure of around 180 bar and a temperature of 540 o C.steam Power Plant ppt | Boiler | Power Station,steam Power Plant ppt.
