air (SCA), low NOx burner (LNB), fuel-gas recirculation (FGR), etc. (Kokkinos, 1994; Bozzuto et al., 1994; Rest et al., 1999). The technique of after-treatment, the so-called flue-gas De-nitrification (DE-NOx), is to treat the NOx formed in flue gas during combustion. It mainly includes selective non-catalytic

01/08/2018 · In order to reduce the adverse effect of hazardous substances on the environment, the flue gases are to be compulsorily cleansed of nitrogen oxides. The use of the sludge resulting from coagulation and liming of natural water during the chemical water treatment at Kazan CHPP-1 as a sorption material is proposed.

26/09/2018 · There are many ways of reducing NO x emissions in the flue gases of natural gas boilers see Nitrogen Oxides (NO x), Why and How They Are Controlled, US Environmental Protection Agency, 1999, for an excellent overview of all the technologies. However, for boilers between 500kW and 32MW, the basic FGR technique can provide a practical and cost-effective solution.

Flue gas treatment | technology | Britannica

Flue gas treatment has achieved the greatest success in reducing particulate matter, nitrogen oxides, and sulfur dioxide. In a typical treatment process, the gas is first sent to an electrostatic precipitator, although fabric filters can be used as well. That device removes ash and other particulates by electrostatically charging them, causing them to be attracted to and deposited on plates or other

Thermal Insulation Coating - Energy Saving Coating - Heat

UGAM HRTI 600 EPSI is mainly suggested for Furnace, Boilers, Freezer vans, ovens up to 550 degrees C or any surface needing heat insulation. In industries where heat is used for process, UGAM Thermal insulation coating are used for energy saving purpose up to 1800 degrees C.

Flue Gas Treatment - Hitachi Zosen Inova AG

The temperature of flue gas from the incinerator is lowered by a waste heat boiler economizer and cooling tower. Fly ash hydrogen chlorides sulfuroxides and dioxins are removed by the filter-type dust collector while nitrogen oxides are removed by the denitrification tower.

Boiler Combustion |

The two main gases your gas condensing boiler produces are water vapour and carbon dioxide. Nitrogen oxide can also be created when the oxygen and nitrogen in the air are burned together. If your boiler isnt burning the gas correctly, carbon monoxide could be produced too. Boilers are made to be safe, and these gases shouldnt harm you.
