Selective Catalyst Reduction Catalyst denitration catalyst for gas
boiler
Product Description
1.The gas boiler flue gas composition analysis
The fuel of commercial boilers is generally natural gas. The fuel
is mixed with air, which releases a lot of heat after being ignited
and burned by a special burner, and then exchanges heat with a heat
exchange medium, and provides hot water or steam for end users for
production and life through pipelines and conveying equipment. The
flue gas generated after combustion of the mixture is discharged
into the atmosphere through flue, thermostat and exhaust pipe.
Particulate matter (PM), sulfur dioxide (SO2), carbon monoxide
(CO), nitrogen oxides (NOx), etc. will be produced in the
combustion process, causing pollution to the surrounding
atmospheric environment.
2.Working principle
Selective catalytic reduction technology is a typical gas-solid
catalytic reaction. NOx in flue gas of gas-fired boiler and urea
solution injected into pipeline (urea solution is decomposed into
ammonia NH3 at a certain temperature) undergo reduction reaction
under the action of SCR catalyst to generate nitrogen N2 and water
H2O, so as to eliminate NOx. In the process of SCR catalytic
reduction, the role of catalyst is to reduce the activation energy
of reaction between NH3 and NOx. Meanwhile, the porous structure on
the surface of catalyst carrier has large specific surface area and
strong adsorption effect, which makes NH3 molecules enrich on the
surface of carrier, increases the contact area between NOx and NH3,
improves the reaction rate and speeds up the reaction. With the
help of a specific SCR catalyst, NOx can be chemically reacted at a
lower temperature, which ensures the reaction efficiency at low
temperature and the high efficiency of denitration equipment under
the whole operating condition.
