The condensing economizer is on a by-pass of the flue gas flow from boiler. The exemplary flue gas temperature entering the condensing system is 150°C. This system is designed to handle only a part of flue gas. In the described example, the flue gas leaves the condensing economizer at 50°C, and the mix of two streams enters the stack at about 120°C.Learn More
The flue gas flows at the boiler outlet inherently have heat potential at a high temperature level. A flue gas heat exchanger is great to use in order to prevent unnecessary flue gas losses. This efficiency component extracts heat from the hot flue gas and, in return, preheats feed water – this, in turn, reduces the fuel expenses for steam generation.Learn More
In this process, temperature varies in the flue gas as well as in the water/steam side. It is important to know these variations for effectively designing the boiler system. Hence, a 3-D mathematical model was developed and CFD simulations were performed for the fuel/flue gas section of a fire tube boiler system using COMSOLLearn More
Jun 19, 2019 · Flue Gas Recirculation (FGR) is the process of taking a portion of the flue gas from a combustion process and recirculating it back through a boiler or burner. When the process is used in internal combustion engines it is commonly referred to as exhaust gas recirculation (EGR). FGR has two primary purposes and one just for gasifiers.Learn More

Mitsubishi Power has compiled more than 40 years of experience in the supply of highly reliable SCR catalyst for its sophisticated flue gas treatment systems, contributing to the prevention of air pollution. Our SCR system has been applied to many types of boilers, HRSGs, and heaters that burn various fuels.Learn More
Flue gas system. The flue gas system starts where the boiler ends and has the task of removing the flue gases produced during combustion safely to the atmosphere. This includes the exhaust pipes inside and outside the boiler room, the chimney and additional built-in components such as expansion joints, silencers or flue gas dampers.Learn More
The flue gas system uses the boiler exhaust as its source, so it is important that the fuel/air ratio in the boiler burners is properly regulated to ensure that high quality inert gases are produced. Too much air would result in an oxygen content exceeding 5%, and too much fuel oil would result in carryover of dangerous hydrocarbon gas.Learn More
A conventional feedwater economizer reduces steam boiler fuel requirements by transferring heat from the flue gas to the boiler feedwater. For natural gas-fired boilers, the lowest temperature to which flue gas can be cooled is about 250°F to prevent condensation and …Learn More
An SRU flue gas waste heat recovery system can be installed with any natural gas or LPG fired power burner boiler or heating unit. When the heating unit is required to operate on oil the flue gases will have to be bypassed from the waste heat recovery unit. Flue gas recovery systems have been used around the world for over 20 years.Learn More
Flue gas heat exchanger for steam boilers With the effective recovery of flue gas heat, you can save up to 14% on fuel and, at the same time, reduce emissions. A flue gas heat exchanger, also called an economiser, is part of the standard equipment for energy-optimised and environmentally friendly boiler …Learn More
Flue Gas Analysis is performed by inserting a probe into the flue of the furnace, boiler, etc., between the last heat exchanger and draft diverter or any source of make-up air that could enter the flue that did not pass through the combustion process. This is known as 'in-situ' testing.Learn More
Apr 01, 2010 · The temperature of the flue gas leaving the boiler is commonly reduced in an air preheater (APH) when the sensible heat in the flue gas …Learn More
These systems have ranged from modifying the RTR model to all stainless for condensing natural gas combustion below 150°F to preheating boiler feedwater from bio/landfill fired boiler exhaust. Impossible to some, but for one of the largest hospitals in Manhattan we designed and manufactured a large customized RTR unit (lower-left photo) that Learn More

Flue Gas Flow Rate Flue gas flow rate is expressed in terms of actual cubic feet per minute (acfm). This flow rate directly affects the size of FGD equipment required for both regenerative and nonregenerative systems. It varies primarily with boiler de-sign, including such factors as operating temperature and exit gas temperature, percent Learn More
The flue gas system washes and cools the boiler flue gas, and delivers it to the cargo tanks during cargo unloading and tank washing. As the flue gas already contains less then 5% oxygen no further treatment is necessary. This system is primarily used on crude oil tankers. The main components are: the scrubber unit, inert gas blowers, the deck water seal, the pressure/vacuum …Learn More
