(PDF) Simulation of flue gas flow in the upper furnace of ...

Flue gas flow through the upper furnace of a kraft recovery boiler has been numerically simulated to examine the sensitivity of the velocity and the temperature distributions to common modelling ...

CN201421080Y - Flue gas waste heat reclaimer for power ...

Abstract. The utility model provides a flue gas waste heat reclaimer for power station boilers. One end of an inlet tube of a heat exchanger is communicated with a pipeline between a gland heater...

Flue Gas Conditioning for Coal Boilers (FGC) - Pentol

Pentol Flue Gas Conditioning adds a small amount of SO3 to the flue gas. Just enough to reduce the fly ash resistivity the ESP can now collect the dust properly and is running at its design capacity. Changing coal is getting easier as the operator can simply

Boiler Economizer: What is it? (Function & Construction ...

Oct 28 2020 · Boiler economizer is a device that uses a portion this remained energy of the flue gas to heat up inlet water (feed water) to the boiler. Since the heat energy is given to the water before it gets fed to the boiler the requirement of fuel for producing steam is optimized. Because of that we call this device as an economizer.

US6609483B1 - System for controlling flue gas exit ...

A system for maintaining an optimal flue gas inlet to a boiler mounted SCR assembly in the flue of the boiler is accomplished by mixing the normal inlet feedwater to an economizer of the boiler...

Experiment on fine particle purification by flue gas ...

Jul 01 2017 · When the inlet gas temperature is between 200 °C and 300 °C the ST-type can be used. In the experiment by choosing the ST-type (condenser B) to purify the real flue gas the temperature drops to nearly 159 °C on average which shows better flue gas condensation performance than the simulation. This is mainly because there is slight vacuum pressure in the gas duck which can increase the heat

Flue Gas Conditioning - Fuel Tech Inc

By injecting SO 3 and in some cases ammonia into the flue gas the performance of Electrostatic Precipitators (ESPs) is improved without increasing SO X emissions. The conditioning gas necessary for the FGC process is produced by burning elemental sulfur to produce SO 2 which is converted to SO 3 with a catalyst and injected into the flue gas at levels normally less than 20 ppm.

Flue Gas - an overview | ScienceDirect Topics

Flue gas (sometimes called exhaust gas or stack gas) is the gas that emanates from combustion plants and which contains the reaction products of fuel and combustion air and residual substances such as particulate matter (dust) sulfur oxides nitrogen oxides and carbon monoxide (Table 3.7). When burning coal and/or waste materials hydrogen chloride and hydrogen fluoride may be present in the flue gas
