A heat exchanger utilisation the waste heat in flue gas of the steam boiler or steam generator itself for increasing the boiler efficiency, is called an ECONOMISER. It can be used for preheating the feed water, but also for external purposes including preheating of make-up water, domestic water or central heating water.Get Price
The superheater works like coils on an air conditioning unit, however to a different end. The steam piping (with steam flowing through it) is directed through the flue gas path in the boiler furnace. This area typically is between 1300–1600 degrees Celsius (2372–2912 °F). Some superheaters are radiant type (absorb heat by thermal radiation Get Price

Find a) The rate of fuel consumption in ton/hr and the flame temperature.Get Price
Jul 13, 2009 · 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. In its basic form these are bundles of water or steam carrying tubes paced in the hot gas flow path. These recover the heat from the gas to generate superheated steam, hence the name Heat Recovery Steam Generator.Get Price

Alfa Laval Aalborg offers a series of highly efficient waste heat recovery boilers that extract heat from hot flue gases and generate steam or hot water. A boiler is easily added to your flue gas stream and recovers heat that would normally be released into the air through a chimney. There are many possibilities to profit from recovered heat.Get Price
Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Vasthi Engineers offer the latest and most innovative flue gas analyzers to monitor the composition of the flue gas of a boiler heating unit to determine if the mixture of Get Price
Heat Recovery Steam Generators and Waste Heat Boilers . Ali Rezaie Navaie. Berlin 2017 . that connect the gas turbine system to the steam cycle. The thermal design and the optimization of an HRSG are important for achieving safe operation, higher efficiency and reduced product cost in a number of rows in flue gas direction, number of Get Price
A gas generator is described which uses fine-grained coal and includes a steam boiler, a combustion boiler and a stack leading from the combustion chamber to the steam boiler. The steam boiler is provided with a slanting bottom portion for the discharge of fly ash and slag.Get Price
A Steam boiler is a steel pressure container in which water under pressure is transformed into steam by the use of combustion. In other words, the boiler is just a heat exchanger which uses radiant heat and hot flue fumes, released from burning fuel, to produce vapor and hot water for heating and processing loads.Get Price
Nov 05, 2019 · Boiler flues are fitted when using combi, regular, and system boilers. The only exception that may apply to a small number of homeowners is a back boiler. This is a type of boiler that is fitted behind a fireplace. If you have a gas boiler behind your fire, the emissions will exit through your chimney, rather than via a boiler flue.Get Price
needed for the flue above the top plate. Put the ends and flue temporarily in place, mark off the position of y, and drill half a dozen 5/32-inch screw holes through y and the flue. Also drill screw holes to hold the collar to the boiler top. The steam-pipe is a circle of 5/16-inch copper tube, having one end closed, and a number ofGet Price
The economizer will incorporate a flue gas bypass with isolating dampers to cover for periods when oil is used and for maintenance. The dampers require electric interlocks to the selected fuel. As the majority of shell boilers operate in the pressure range 7–10 bar, the flue gas outlet temperature will be in the range of 190–250°C.Get Price
the process steam when the gas turbine is tripped or out of operation for maintenance is advantageous. The integration of gas turbines and heat recovery steam generators into the water/steam process of conventional boiler plants. The heat recovery steam generator is either connected on the water, the live steam or on reheat side with theGet Price
Apr 16, 2021 · Inert Gas System (IGS) on a ship refers to a system deployed for the prevention of an explosion in the cargo tanks of a tanker. In this integrated system, while pumping out the liquid inflammable cargo, an inert gas (sometimes by flue gas from ship boilers) is also pumped in. An oil tanker's job is to carry different types of oil that vary in Get Price
These boilers are also known as heat recovery steam generators. High-pressure steam from these boilers can be used to generate additional electric power with steam turbines, a configuration called a combined cycle. A simple cycle gas turbine can achieve energy conversion efficiencies ranging between 20 and 35 percent.Get Price

About OTSG. Once Through Heat Recovery Steam Generators (OTSGs) are the most significant advancement in steam generation in over a century. Until the 1980s, conventional drum boilers were used to produce steam. At about this time, the US Navy investigated the use of combined gas turbine and steam turbine plants for additional ship propulsion power.Get Price
