Boiler Drum is a very crucial part in case of Sub-critical boilers. It is cylindrical in shape and situated at the top of the boiler. In Super-critical units, water is directly converted into steam so drum is not required, but in case of subcritical boilers, the whole water quantity is not directly converted into steam. […]

Large thermal power plants generate electricity by using the thermal energy of fuel. Most of the power plants are pulverized coal fired boiler that means thermal energy is generated by the combustion of pulverized (crushed) coal.In order to control the combustion process,every power plant has their Burner Management System/FSSS(Furnace Safeguard Supervisory System) system,but Optimum efficiency is […]

In our previous articles, we have explained you the Water Cycle of thermal power plant. This Water cycle consists of Feed Water Cycle and Condensate Water Cycle. Condensate water cycle is from Condenser to the Deaerator and feed water cycle is from Deaerator to the Boiler Drum. Impact of Dissolved gasses in Feed-water It is an utmost necessary […]

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 […]

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 […]
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 […]
