BOILER INSTALLATION GUIDE - MemberClicks

B. Flue Gas Recirculation (FGR) systems have an additional issue, because high stack pressures can result in rich burner operation. A higher stack pressure will force more flue gas into the burner, reducing the combustion air flow causing a fuel rich condition with the potential for an explosive condition.

Boiler (power generation) - Wikipedia

The denser column of ambient air forces combustion air into and through the boiler. The second method is through use of a steam jet. The steam jet or ejector oriented in the direction of flue gas flow induces flue gases into the stack and allows for a greater flue gas velocity increasing the overall draught in

Flue gas - Wikipedia

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.Quite often, the flue gas refers to the combustion exhaust gas produced at power plants.Its composition depends on what is being burned, but it will usually consist of mostly nitrogen (typically more than two-thirds) derived

Flue gas flow rate measurement errors. Interim report

Jun 01, 1996 · The CEMS flue gas flow rate monitor is suspected to be one of the factors contributing to this high bias. Since the flue gas flow rate monitors are certified and calibrated using EPA Methods 1 and 2, there is concern that the bias is not from the flue gas flow rate monitor directly, but rather from the Methods 1 and 2 procedures.

Investigation on Residual Swirl and Flue Gas Imbalance in

There exists the serious problem of flue gas imbalance at the entry of horizontal gas-pass in many large tangentially fired utility boilers used presently in China. In this paper, the experimental and computational investigations on residual swirl and flue gas imbalance are carried out based on an isothermal model of 600 MW tangentially fired boiler.

Pilot plant experience in electron-beam treatment of iron

The peresent development status of the electron-beam flue gas treatment process, which is a dry process capable of removing SOx and NOx simultaneously, is described. The most advanced demonstration of this process was accomplished with a pilot plant in Japan where the maximum gas flow rate of 10,000 Nm 3 /h of an iron-ore sintering machine flue gas was successfully treated.

Gas Firedbined Thermal Oil Boiler Export Type

A flue-gas stack, also known as a smoke stack, chimney stack or simply as a stack, is a type of chimney, a vertical pipe, channel or similar structure through which combustion product gases called flue gases are exhausted to the outside air. Flue gases are produced when coal, oil, natural gas, wood or any other fuel is combusted in an industrial furnace, a power plant's steam-generating boiler, or other large combustion device. Flue gas
