SCR Denitrification Catalyst--For Coal Fired Boilers Low Medium And High Temperature Various Specifications And Sizes

Technical Specification: The Coal-Fired Boiler DeNOx Catalyst is installed within the SCR system to enhance the efficiency of the catalytic reduction process. It maximizes the contact between the flue gases and the catalytic surface, thereby promoting a higher rate of NOx conversion. This technology is widely used in coal-fired power plants and industrial boilers to meet emissions targets and regulatory requirements.

DeNOx Honeycomb Catalyst Working Principle:

The Coal-Fired Boiler DeNOx Catalyst is primarily used in coal-fired boilers that are equipped with Selective Catalytic Reduction (SCR) systems. SCR systems are a widely adopted technology for reducing nitrogen oxide (NOx) emissions from flue gases produced by coal-fired power plants and industrial boilers. Here's how the system works:

Coal-Fired Boiler:

The coal-fired boiler burns coal to produce steam, which is used to generate electricity or for industrial processes. However, this combustion process releases various pollutants, including nitrogen oxides (NOx).

Flue Gas Treatment:

After combustion, the flue gases from the boiler contain pollutants like NOx. These gases are directed through a flue gas treatment system before being released into the atmosphere.

Selective Catalytic Reduction (SCR) System:

The SCR system is a crucial component of the flue gas treatment system. It contains the DeNOx catalyst. The catalyst promotes a chemical reaction that converts the NOx gases into nitrogen (N2) and water vapor (H2O), which are harmless components.
