critical parameters are silica,tds, ph, po4,na+,alkanity
operation boiler and tarbine
Benson Boiler is a water tube high pressure boiler having forced circulation. It works on the principle that if the boiler pressure is raised to critical pressure (225 kg/cm^2) then there is no formation of steam bubbles Because the steam and water at this pressure will have the same Density. To achieve this water is fed to the boiler at critical pressure . At this pressure water will be directly converted to superheated steam as the latent heat at critical pressure is zero. Overall efficiency of plant is decreased as a lot of energy is consumed by feed water. Operating the boiler at a slightly lower pressure than the critical pressure efficiency can be increased. Thermal efficiency upto 90% can be achieved.
A Furnace works by heating the power plant with the fuel provided you idiot... how else do you think it works??
to give accurte pathway to the air flue gas...:)as we need accurate path to walk same as air...
Air Preheaters (APH) are important equipments in modern thermal power stations. By preheating the combustion air with the hot flue gases coming out of the boiler, a considerable increase in efficiency is obtained.
In Cogeneration Plant : The generated steam in boiler is used for both power generation & process heating, thereby reducing the condenstion losses compared to thermal power plant. In combined cycle first is gas turbine , rather than wasting the flue gas from gas turbine, we are sending it into boiler and again generating steam for running steam turbine. Both the ways we are increasing the thermal efficiency of the plant
It removes the gases present in the steam,given by heaters.dearater is necessary otherwise the gases in steam will corrode the boiler and also affect the turbine.
waste heat recovery boiler is the boiler which takes the waste heat produced by the industries and produce power for example if you take sulfuric plant where the output gas is taken and connected to boiler and power is generated , one of the best manufactures in India is Thermal Systems who is poineer in the Market.for more information you can visit http://www.thermalindia.com/
A hotwell in a thermal power plant is a reservoir or tank that collects condensate from the turbine exhaust steam and other feedwater sources. It helps in recovering and recycling the steam condensate to maintain efficient water circulation in the power plant's boiler system. The hotwell also serves as a storage tank to supply feedwater to the boiler as needed.
to remove the oxygen and carbon di oxide in boiler feed water we are the various deaerator mechanical deaerator spry typr vaccum type likr thwt
how to measure Temperature in thermal power plant
Natural Cancained clay is used for making refractory bricks and shapes.But it find best and cheap use in the boiler of thermal power plants as a bed material. Because here it does not required any benification or calcination. you have to only to make grains (iron free) of required sizes which is directly used in the boiler of a thermal power plant as a bed material
