Operational Facts of Excellent Heat Recovery Steam Generator

In case of any Heat Recovery Steam Generator, the gas temperature decides how much energy recuperated from the vent gas stream, which is characteristic of productivity. Thus, endeavors are regularly made to bring down this temperature as much as expected thinking about cost adequacy and low-temperature erosion concerns. O’Brien has the most advanced option in this case that works efficiently.  

The gas temperature is free of steam pressure in a regular Steam Generator. The gas temperature of around 300 F can effectively involve an economizer as the hotness recuperation gear. Anyway, in a gas turbine HRSG, the leave gas temperature is an element of gulf gas temperature, feed-water temperature, and steam pressure because of thermodynamic reasons. 

The low fumes gas temperature from gas turbines, normally going from 900 to 1050F, creates less steam on the unit gas mass premise in the HRSG evaporator. Then again, in a steam generator, the pipe gas stream is cooled from an ignition temperature of 3300 F and consequently creates a lot of steam on unit gas. 

The little proportion of steam to the gas stream in a Heat Recovery Steam Generator is not sufficient to cool the fumes gasses in the economizer, bringing about a high leave gas temperature. The higher the steam pressure, the higher the leave gas temperature and the other way around. Anyway, different choices are accessible for bringing down the leave gas temperature, which further develops the HRSG productivity. 

Measured HRSGs can be sorted in various ways, for example, heading of exhaust gasses stream or number of strain levels. Given tension levels, HRSGs can be ordered into single strain and multi pressure. Single strain HRSGs has just one steam drum and steam is created at a single tension level though multi pressure HRSGs utilizes a few steam drums. Each segment has a steam drum and an evaporator area where water is changed over to steam.
