waste heat boiler and hrsg,heat recovery steam

2019-4-8·A heat recovery steam generator (HRSG) is an energy recovery heat exchanger that recovers heat from a hot gas stream. It produces steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle). The term HRSG refers to the waste heat boiler in a Combined Cycle Power Plant.

Economizer - Wikipedia. The first successful economizer design was used to increase the steam-raising efficiency of the boilers of stationary steam engines.It was patented by Edward Green in 1845, and since then has been known as Green's economizer.It consisted of an array of vertical cast iron tubes connected to a tank of water above and below, between which the boiler's exhaust gases passed.

Steaming in Boiler,HRSG Economizers

The ratio of gas flow to steam remains nearly constant at all boiler loads,as we reduce the air flows when steam demand or load decreases.Hence the economizer duty is such that the enthalpy absorbed at low loads is lower.The figure above shows the boiler vs HRSG water exit

Boiler | Engaged in Thermodynamics

The economizer is the last component of the feedwater system. The economizer extracts heat from the exhaust gas to heat the steam to further improve boiler efficiency. Feedwater enters the boiler though the economizer and rises as steam to the steam drum, where the water and steam are separated.

Economizer - an overview | ScienceDirect Topics

The feedwater control valve is usually located at the outlet of the feedwater pump before the condensate enters the economizer in a typical HRSG arrangement. This control valve could be located at the outlet instead of the inlet of the economizer. It is desirable for each boiler to have its own economizer. Where one economizer is

Use Feedwater Economizers for Waste Heat Recovery

2017-6-3·A feedwater economizer is appropriate when insufficient heat transfer surface exists within the boiler to remove combustion heat. Boilers that exceed 100 boiler horse-power, operating at pressures exceeding 75 psig or above, and that are significantly loaded all year long are excellent candidates for an economizer retrofit.
