The agent breaks down the NO x in the exhaust gases into water and atmospheric nitrogen (N 2 ). While NSCR can reduce boiler NO x emissions by up to 70%, it is very difficult to apply to industrial boilers that modulate or cycle frequently because to perform properly, the agent must be introduced at a specific flue gas temperature.

Superheated Steam Boiler Manufacturers| Industrial Boilers

The steam piping is directed through the flue gas path in the boiler furnace. The temperature in this area is typically between 1300–1600 degrees Celsius (2372–2912 °F). Some superheaters are a radiant type; that is, they absorb heat by radiation. Others are a convection type, absorbing heat from a fluid. Some are a combination of the two

Technical advice on boiler combustion control

Ensuring that the heat-transfer surfaces of the boiler are clean is a major point of focus for managing the thermal energy in exhaust gases. Energy can be recovered from exhaust gases by transferring thermal energy from the high-temperature gases to boiler feedwater, or to the combustion air entering the boiler.

What are the requirements for the exhaust gas temperature

Fuels - Exhaust Temperatures

The flue gas exit tempera ture from a boiler is usually maintained at a minimum of 200 o C, so that the sulphur oxides in the flue gas do not condense and cause corrosion in heat transfer surfaces. When a clean fuel such as natural gas, LPG or gas oil is used, the economy of heat recovery must be worked out, as the flue gas temperature may be well below 200 o C.

Industrial Gas Boilers- Condensing - 30 kW to 12,160 kW

Jun 28, 2018 · In the exhaust gases from a gas fired industrial boiler, water vapour is always present due to the hydrogen bound in the fuel. This water vapour begins to condense at a certain temperature (similar to the humidity that precipitates on a cold windowpane). This condensing temperature is approximately 55 ° C for gas fired boilers.
