Heat Recovery Steam Generators - HRSG,s are an important part of the Combined Cycle Plant. How is it different from the combustion boilers? Some of the main differences are given in this article. Heat Recovery Steam Generator's (HRSG's) are waste heat boilers. The steam turbine or a downstream process uses the steam. The term HRSG refers to the waste heat boiler in a Combined Cycle Power Plant.
Jan 01, 2013 · Steam generation has the advantage that piping costs may be less due to proximity of steam headers in the plant; its disadvantage is that steam header pressures at a petroleum refinery, for example, are usually fixed, and hence, cannot maximize the amount of possible heat recovery.
A simple power plant cycle The steam boiler provides steam to a heat consumer, usually to power an engine. In a steam power plant a steam turbine is used for extracting the heat from the steam and turning it into work. The turbine usually drives a generator that turns the work from the turbine into electricity. The steam, used by the turbine, can
To get the best efficiency for a combined cycle plant the Heat Recovery Steam Generators (HRSG) operates on with three different pressure circuits. This article explains why this is required.In an HRSG, as in any boiler, water converts to superheated steam in three different sections. The economizer , the evaporator and the Superheater. Heat transfer is dependent on the mass flow of the hot
In a CCGT plant the thermal efficiency is extended to approximately 50-60 per cent, by piping the exhaust gas from the gas turbine into a heat recovery steam generator. However the heat recovered in this process is sufficient to drive a steam turbine with an electrical output of approximately 50 per cent of the gas turbine generator.
In the facilities, a regenerator-heated, diffusion-combustion micro-gas turbine is used, and its high combustor inlet temperature enables high thermal efficiency of ammonia combustion compared with that of methane combustion. Adoption of the regenerator increased combustor inlet temperature and enhanced flame stability in ammonia-air combustion.
The deaerated water will be pumped to 3 HRSGs by 3×50% High Pressure “Boiler Feed Water Pumps” to meet the hot gas coming from gas turbines. This leads to the evaporation of DM water to high pressure steam. The steam Produced from 3 HRSGs will be collected in a main header and is sent to battery limit of Urea Ammonia Plant.
