What is the low temperature of the steam generator

Boiler Efficiency | How to balance steam loads efficiently Understand characteristics of boilers and heat recovery steam generators …

26/8/2011 · If we generate the same additional 25,000 lb/hr steam in a steam generator, the additional fuel input (Table 1) is about 27.2 million Btu/hr on LHV basis. Another way to look at the efficiency of both boiler types is this: The HRSG generates an additional 75,000 lb/hr of steam with a fuel input of only 75.6 million Btu/hr (subtract the fuel input at 100,000 lb/hr steam from the unfired case

17/8/2021 · The low exhaust gas temperature from gas turbines, typically ranging from 900 to 1050F, generates less steam on unit gas mass basis in the HRSG evaporator compared to a package boiler. On the other hand, in a steam generator or package boiler, the flue gas stream is cooled from adiabatic combustion temperature of 3300 F and hence generates a large amount of steam on unit gas mass …

Options for Improving the Efficiency of Heat Recovery Steam Generators …

17/8/2021 · In any heat transfer equipment such as a boiler or Heat Recovery Steam Generator (HRSG), the exit gas temperature determines the amount of energy recovered from the flue gas stream, which is indicative of efficiency. Hence efforts are often made to lower this temperature …

Steam Inlet Temperature - an overview | ScienceDirect Topics

generate high-pressure/high-tempera-ture superheated steam (600-1,500 psig at 650-950°F), while small capacity plants (10-MW gas turbines and below) may generate low-pressure saturated steam (100-300 psig). The superheated steam temperature in a HRSG is controlled using spray desuperheaters as in conventional boilers. Steam temperature varies with gas inlet conditions, so performance should be …
