The superheated steam then finally goes to the turbine.Final Superheater temperatures are in the Range of 540 to 570 °C for large power plants and SuperHeated steam pressures are around 175 bar. Reheater . Steam from the exhaust of the first stage turbine goes back to the boiler for reheating and is returned to the second stage.
and boiler water that contacted the metal surface boiled. A tube in a boiler behaves just like a frying pan on a stove. If you throw tap water on a hot frying pan, the water boils away and leaves behind a white residue of dried salts. In a boiler, there is a constant flow of water across the tube surface, and the tube surface usually does not ...

Unless a superheater is used, this will cause the steam supply to become partially wet (wet steam) from the added liquid. Steam Dryness Fraction. The steam dryness fraction is used to quantify the amount of water within steam. If steam contains 10% water by mass, it's said to be 90% dry, or have a dryness fraction of 0.9.
The steam drum is primary used on water tube boilers and HRSGs. It contains internals such as the agglomerators and the cyclone separators, chevrons, demister pads, and any combination thereof. The primary function of the steam drum is separate water from steam which prevents carryover of the condensate into to the steam header (phase separation).
Boilers are basically vessels used for heating the water and converting it to steam, as the name suggests. Boilers vessels generally use an internal heat source for boiling the water. Generally the steam is used as a utility in process plants and needs to be available at certain temperature and pressure conditions.
Heat recovery steam generator is a high-efficiency steam boiler that uses hot gases from a gas turbine for reciprocating engine to generate steam in a thermodynamic Rankine Cycle. This system is able to generate steam at different pressure levels according to chemical process requirements (PGTHERMAL, 2009). HSRG system can use single, double ...
But in evaporater the fuel us used as a heating sources is may be the boiling water or a steam but for boilers fire flame is used as coal or a gas. There is also a difference in temperatures of both the equipments, boilers operate at high temperatures whereas evaporator operates at lower temperature than boilers.
The results show that the maximum heat transfer occurs in the evaporator section for high-pressure levels, and in the economizer section for low-pressure levels. The optimum design pressure for the high-pressure level of the steam generator was found to be 100 bar, while that for the low-pressure level was found to be 10 bar.

Loeffler Boiler is a forced circulation, high pressure, and water tube boiler with internally fired furnace. In this boiler, the 2/3 of superheated steam is used to evaporate the water in the evaporating drum and remaining 1/3 of the steam from the superheater is used by the turbine.
In boilers with low steam pressure, the share of the heat needed for evaporation is bigger than when considering a high-pressure boiler. Thus the furnace-wall evaporator cannot provide enough heat for evaporation process in low-pressure boilers. Convection evaporators supply the supplementary heat needed for complete evaporation.
Waterside Deposits in evaporator tubes have been an issue in steam generators as long as boilers have been used. Substantial experience in deposit formation and management has been gained in conventional goal and oil/gas boilers over time. The role of boiling modes in the steam generator tubes is very critical to areas of deposit formation.
A common application of economizers in steam power plants is to capture the waste heat from boiler stack gases (flue gas) and transfer it to the boiler feedwater. This raises the temperature of the boiler feedwater, lowering the needed energy input, in turn reducing the firing rates needed for the rated boiler output.
Economizer is an accessory of boiler that recovers the waste heat from the flue gas blown out of the boiler. Thus it actually "economizes" the operational cost or in other words, improves the ...
