2/2/2011 · Kefid Isobaric Heat Transfer.High pressure liquid enters the boiler from the feed pump (1) and is heated to the saturation temperature (2). Further addition of energy causes evaporation of the liquid until it is fully converted to saturated steam (3). 3-4 Isentropic Expansion..

Boiler Efficiency | How to balance steam loads efficiently …

26/8/2011 · A fired HRSG is more efficient than an unfired HRSG. This is because gas turbines have a more-or-less constant exhaust gas flow and the steam generation is varied by adding the fuel. This is possible because the excess oxygen in typical turbine exhaust gases is 15%.

Options for Improving the Efficiency of Heat Recovery Steam …

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 as much as possible taking into consideration cost effectiveness and low temperature corrosion concerns. In a conventional steam generator …

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

26/8/2011 · Many process plants, refineries and chemical plants have package boilers (Figure 1) and supplementary gas-fired heat recovery steam generator (HRSG) (Figure 2). Without a clear understanding of the thermal performance characteristics of these two types of steam generators, plant engineers often don't assign loads to them judiciously so that the total plant steam is generated most efficiently.

Boiler and Condenser Pressures - Rankine Cycle | nuclear …

Decreasing the turbine exhaust pressure significantly increases the specific volume of exhausted steam, which requires huge blades in last rows of low-pressure stage of the steam turbine. In a typical wet steam turbines, the exhausted steam condenses in the condenser and it is at a pressure well below atmospheric (absolute pressure of 0.008 MPa, which corresponds to 41.5°C).
