Flue gas recirculation, or FGR, is the most effective method of reducing NOx emission from industrial boilers with inputs below 100 MMBtu/hr. FGR entails recirculating a portion of relatively cool exhaust gases back into the combustion process in order to lower the flame temperature and reduce NOx formation.

Low-NOx Burners for Industrial Boilers | HPAC Engineeri

Steam injection—injecting steam into a flame—works because steam temperature is considerably lower than flame temperature—in the case of a boiler operating at 300 psig, 421°F vs. 2,400°F to 3,400°F. Also, steam is pure water, which is not free oxygen.

emissions are minimized when combustion temperatures are kept high (above 1475oF) and excess oxygen is kept to a minimum (less than 1 percent). Methane emissions are highest during low-temperature combustion or incomplete combustion, such as the start-up or shut-down cycle for boilers. Typically, conditions that favor formation of N2O

GAS TECHNOLOGY: Boiler NOx Emissions - Plant Engineeri

In many areas, industrial boiler operators face stricter regulation of NOx emissions, even with the use of clean natural gas. In some areas, operators are required to meet what are called “Ultra-Low NOx” (ULN) requirements, typically less than 10-12 ppm. It is widely believed that the ULN requirements will be broadened to more areas. In […]

Flue-gas stack - Wikiped

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

Fluidized bed combustion - Wikiped

Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels.. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.

The condensation causes a loud noise that can be heard throughout the plant and can shift the steam pipes 6 to 7 inches out of place. Superheaters extract all of the liquid water from the steam by raising the temperature of the steam well above the saturation point. The superheater uses the additional energy to heat the steam exiting the boiler.
