Feb 02, 2015 · The slagging and fouling characteristics of the heat recovery steam generator (HRSG) for ferrosilicon electric furnaces are discussed in this paper. at Grundartangi goes out (PDF) The CFD Modeling of Heat Recovery Steam Generator The axial velocity and temperature distributions at the outlet section of inlet diffuser of Heat Recovery Steam Generator (HRSG) channel should be uniform as much as possible to avoid overheating Fresh Air Firinga steam generator. However, keep in mind that the ratio of flue gas to steam is about 1.1 in a steam generator, while in an HRSG, it will be in the range of 68, and so a large amount of exhaust gas is heated from ambient conditions relative to steam generation and then vented to the atmosphere.
The function of the combined cycle heat recovery steam generator (HRSG) system is to provide a method to extract sensible heat from the combustion turbine (CT) exhaust gas stream. The heat is converted into usable steam by the heat transfer surfaces within the HRSG. Heat Recovery Steam Generator DaeKyung EngineeringThis program is called HAD-HRSG, which is a program to design a heat recovery steam generator for high-temperature exhaust gas or waste gas at the exhaust of gas-turbine. The program can calculate the following contents. Heat Recovery Steam Generators Heat recovery steam generators can be fired or unfired, depending on whether additional fuel is burnt. There are two modes of firing:1. Supplementary firing, if the fuel (oil or gas) is burnt for generating part of the steam need. 2. Auxiliary firing, if the fuel is burnt for generating 100% steam. In both cases duty may be continuous or intermittent.
Oct 01, 2019 · Oct 01, 2019 · Heat recovery steam generator 1. Heat Recovery Steam Generator (HRSG) Components, Aux Sys, Supplementary Firing 2. Definition of HRSG HRSG is composed of economizer, evaporator, superheater and its accessories. Hot gas exhaust temperature reduces from 540 to 150-180 while it passes through superheater, evaporator, economizer. Reheat Steam Cycle - an overview ScienceDirect TopicsAs seen from the above plant process description, the function of an HRSG is to recover heat from the exhaust of a gas turbine to generate steam. The principal mode of heat transfer from gas to water or steam in an HRSG is by convection. The tubes through which water or steam flow are finned to enhance heat transfer surface area. Slagging and Fouling Characteristics of HRSG for The slagging and fouling characteristics of the heat recovery steam generator (HRSG) for ferrosilicon electric furnaces are discussed in this paper. Three ash samples were taken from the HRSG of a ferrosilicon furnace in Ningxia Province, China, which suffered from serious slagging and fouling. X-ray fluorescence (XRF), X-ray powder diffraction (XRD) and scanning electron microscope (SEM) were
Jan 01, 2017 · A typical vertical gas flow, horizontal tube, forced circulation HRSG with two levels of steam pressure is shown schematically in Fig. 17.1.Gas that exits the gas turbine horizontally from the left turns upward in the turning duct, flows across the horizontal tubes and exits to the atmosphere from the stack at the top of the unit. Water for the high-pressure portion of the system enters the
