What is the difference between water heater and calorifier?
The water heater has an electric heating element that is responsible to make the water hot if submerged to water. While the Calorifier is composed of steam coil where the steam from boiler passes through, is responsible to make the water hot if it get contact to the steam coil.
What is the difference between pinch point and approach temperature?
Both temperatures are related to the saturation temperature in the steam drum of a heat recovery steam generator. The approach temperature is the water temperature at the economizer outlet, which in many analyses is assumed to be equal to the saturation temperature for simplicity. The "pinch point temperature difference" is the difference between the saturation temperature and the gas temperature at the economizer inlet.
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
What is the difference between sludge and scale?
Hard Scale(Scale) - Forms in steam boiler -Has the appearance of a white and brown concentration -smooth texture Soft Scale(Sludge) -Forms in the hot water heaters -Appears as a thick ,brown or black sludge
What is the difference between a geyser and a fumarole?
A geyser - A fountain of hot water and steam that shoots into the air A fumarole - A "geyser" in which only steam escape So the different is geyser shoot out steam and a fumarole escape
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
What is the difference between a calorifier and a steam generator?
A calorifier produces hot water, not steam, whilst a steam generator obviously produces steam
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 hot water boiler?
A steam boiler a heating unit designed to heat by boiling water, producing steam, and circulating it to radiators or steam baseboard units throughout the home.
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.
How a generator operated by boiler?
The boiler heats water into steam. The steam is pressurized and fed into a turbine which causes it to rotate. As the steam turbine rotates, the connected generator rotates and produces electricity. Make Sense??? Please 'Recommend Contributor'
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
How do you plumb oil boiler and a stove boiler in parallel?
Water or steam? It makes a difference.
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 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.
