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 […]

In any thermal power plant, there are mainly three cycles i.e. Steam Cycle, Condensate cycle and Feed water cycle. We have already discussed the steam cycle in thermal power plant and now we will discuss about the Condensate cycle & Feed-water cycle. These two cycles are very important in efficiency point of view. As we […]

In order to generate electricity, we require mechanical torque and for the mechanical torque we require a fluid which will rotate the turbine, in thermal power plants to rotate the turbine we use steam as a medium. Steam is generated in boiler with the help of coal and water and after burning the coal, the […]
The efficiency of a basic Rankin cycle is very less due to the enthalpy loss in the condenser. So the reheat and the regenerative cycle are used to increase the efficiency of the Rankin cycle.Here we will discuss how regenerative cycle is used in thermal power plant. (Rankin cycle with regenerative feed heating) If the […]
Based on the steam flow: Single-flow: the steam is admitted at the one end of the turbine in the first stage blades. Steam flows axially through the radially-mounted blades and exhausts at the other end after expansion (specific volume is increased). Double-flow: In this type of arrangement the steam is admitted at the center of […]
Boilers operating below the critical pressure are generally fitted with a steam drum, which is known as the heart of the boiler. In the steam drum, the main objective is to separate the steam from the steam-water mixture, which is coming through the riser tubes. Basically In the boiler, the feed-water comes through the feed-water […]
Efficiency Efficiency in turbine is defined as the ratio of the amount of work done by the turbine to the amount of heat transferred to the turbine by the working fluid and the efficiency at which the heat is transferred to the turbine rotating blades is dependent on the ratio of moving blade velocity and […]
