What is the difference between combined cycle and cogeneration?
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
If the pressure in a steam boiler 3.6 bar what is the temperature of the steam?
At 3.6 Bar (52.2 psi) Saturated Steam Temperature would be 148.8 Deg. C (299.9 Deg. F)
Practical application of marcet boiler experiment?
the dry steam produced is used in companies to dry finish products
What is the function of chain grate stoker in water tube boiler?
it is used to burn the fuel(coal,usually) with primary and secondary air.the burning coal is then used to heat the water in the boiler to produce steam.
In a nuclear power plant what is used to change water into steam?
Heat from the nuclear reaction changes water to steam.
What is the difference between a steam boiler and steam generator?
boiler use many type of working fluids like water, Mercury, liquid sodium, etc., but steam generator works only with water as working fluid. hence all steam generator are boilers but all boilers are not steam generators...
What is the area between the steam drum and the mud drum ona boiler?
Generator
Is steam reversible?
Yes. Steam is produced in a steam generator (boiler), used to power an engine (or turbine), condensed, and returned to the boiler as feedwater.
What is the difference between steam boiler and pressure vessel?
Boiler is basically a pressure vessel in which this boiler aims to heat the surroundings which is a pressure vessel.
What is the purpose of boiler drum?
Purpose of the boiler drum is to collect steam from all the various tubes in a boiler, and send it to the turbine to spin the generator
Does combined cycle power plant has a boiler?
No It has heat recovery steam generator
What is difference between 500MW boiler 660MW boiler?
500 MW Boiler is sub-critical Boiler which generates steam at pressure lower than the critical pressure ie below 221.2 kg/sqcm. where as the 660 MW boiler is super critical boiler which operates steam pressure above critical pressure.
How do you plumb oil boiler and a stove boiler in parallel?
Water or steam? It makes a difference.
How do you calculate the gross heat rate of a turbine?
Divide heat added to the boiler between feedwater inlet and steam outlet by the kilowatt output of the generator at the generator terminals. Rate expressed in btu. See article.
What is the difference between steam generating unit and boiler?
A steam generating unit generally is not a self contained unit and allows the steam by-product (water) to escape. A Boiler is generally a sealed system that recirculates the condensed water back to the heating chamber for re-use.
What does a boiler do in a coal power station?
A boiler in a coal power station is responsible for converting water into steam. The coal is burned in the furnace of the boiler, producing heat which is used to generate steam. This steam is then used to drive a turbine, which spins a generator to produce electricity.
What is the difference between the operation of a automatic boiler and manual boiler?
boiler are working on same principal but automatic and manual boiler has difference that manual boiler working at single element loop and automatic boiler work at three element loop.single loop means when fuel increase mean load increase on boiler by adjusting fuel operator has to adjust steam drum level manualy , while automatic means when load increas, fuel increase steam drum level adjust automaticaly by watching fuel consumption.
