Wet Steam vs. Dry Steam: The Importance of the Steam

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.

What is the purpose of the steam drum on a water tube boiler

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

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

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 ...

What is the difference between boiler and evaporator?

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.

Design methodology of heat recovery steam generator in

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.

PDF Heat Exchangers in Boilers

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.

Role of Boiling Mode and Rate in Formation of Waterside

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.

What is the function of economizer in boiler?

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.
