Denitrification Catalyst

Denitrification catalyst is a substance that can reduce NOx in flue gas to N2 and H2O. Common types of denitrification catalysts include plate type, honeycomb type and corrugated plate type. Denitrification catalysts are widely used in industrial fields such as electricity, cement, steel, glass furnaces, and waste incineration power generation. They are an important means to control NOx emissions and prevent air pollution.

Product Features

The technology is mature, the operation is stable and reliable. And a mature and effective process system has been formed.

Mature technology
Which can reach more than 90%, meeting strict environmental emission standards.

The denitrification efficiency is high
Can be controlled at 3ppmv or below, which reduces the consumption of nh3 and saves operating costs.

The ammonia escape is small
The exhaust gas is treated after the kiln combustion process. This treatment method ensures the stable operation of the equipment and the high quality of the product.

Application

When the working temperature is 165℃-220℃, it is used in packaging glass (after waste heat boiler), coking (post-denitrification), garbage incineration, ceramic kilns, chemicals, pharmaceuticals, power plant back-end denitrification (after desulfurization) and other industries.

When the working temperature is 225℃-275℃, it is used in glass (before waste heat boiler), coking (pre-denitrification), sintering machine (low-temperature denitrification) and other industries.

When the working temperature is 280℃-420℃, it is used in power plants, heating boilers, flat glass, sintering machines (medium-temperature denitrification) and other industries.

When the working temperature is 420℃-550℃, it is used in gas units, kiln combustion and other industries.

FAQs

Reasons why the catalyst module cannot be aligned

(1) Deformation of the support beam: When the support beam is slightly deformed, its flatness can be restored by correction; when the support beam is seriously deformed, a new support beam needs to be replaced.
(2) Insufficient thermal expansion reserve: Reasonably set the reserved space or use elastic connection to adapt to the impact of temperature changes.
What to do if a seal leaks

The sealing part may age, be damaged or fall off due to temperature changes, vibrations, etc., causing seal leakage. High-temperature sealant (such as RTV silicone rubber) can be applied.
Startup recommendations

It is recommended to conduct a flue gas distribution simulation test before the first startup to optimize the flow field uniformity (δ<15%). According to the test results, take optimization measures to extend the service life.
