Want to know about the various processes involved while starting a unit? Then you are at the right place because we have stuffed all the details involved in the start-up of a Sub-critical Tangential Firing unit. Below we have explained the start-up procedure types and various processes involved in case of tangential fired sub-critical boiler […]

New generation thermal power plants are larger in capacity and having sophisticated firing systems, which are more expensive. So it has become necessary to have a coordinated fuel burner management system. Why Boiler Protection System? Inside the furnace, for ignition purpose we generally use HFO (Heavy Furnace Oil), LDO (Light Diesel Oil) and Coal as […]

Thermal Power Plant is based on the Rankine cycle and in Ideal Rankine cycle, there are 4 processes and those are Heat Addition at Constant Pressure in Boiler, Isentropic Expansion in Turbine, Constant Pressure Heat Rejection in Condenser and Isentropic Compression in Pumps. So now we will discuss about the condenser, which plays a very […]

Generators are the most expensive equipment in the whole plant and the generator faults are considered to be the serious since they may cause severe and costly damage to the insulation, windings and the core. They may cause severe mechanical damage to the shafts and couplings, thereby increasing the amount of fault damage. In the […]

When the Coal combustion takes place in the boiler, some part of the coal remains unburnt and that un-burnt particles are called the Ash, which is approximately 26% to 40% of the total coal undergoing combustion. Basically this is nothing but the residual part of the coal. This ash will be extracted out in the […]

In the boiler, the feed water and steam flows through the different parts where the pressure is much higher than the atmospheric pressure. These parts are generally known as Boiler Pressure Parts. Mainly the heat addition to the working fluid (Water) is done through these pressure parts. Following are the boiler pressure parts: Boiler Drum […]

As we have earlier seen the function and working of the boiler. In the boiler combustion takes place and coal’s chemical energy is converted into the heat energy. That heat energy is utilised to heat the water and the water is converted into steam which drive the turbine and ultimately energy is generated. In this […]

Modes of Coal Transportation Ship: Generally the coal that is imported from the foreign countries is coming by the Ship. The Coal from the foreign countries comes to a port and at the port the coal is stacked for storage. From the Port by the help of Trucks or Trains, the coal is transferred to […]

Coal & Grading Coal is the primary fuel for the Thermal power plants, the reason coal is preferred more is that it is available in a larger quantity as compared to the other Non-renewable resources And apart from that, it is also cheaper and having a good calorific value. The coal is also categorized into […]
After the coal combustion in the Boiler, Ash and Flue gases are generated. These are nothing, but the Un-burnt coal particles. The heavier un-burnt particles fall down and collected as the bottom ash, while the lighter ash particles flow towards the atmosphere through the chimney due to the furnace draft. These particulate matters, SOX (Sulphur […]
