Three Steps of CEMS:
1st Step: Gas Sampling
2nd Step: Gas conditioning and treatment
3rd Step: Measurement/Calibration
In first step, the function is to get sample gas and forward to 2nd step for treatment. During this step, it cannot block the probes and cannot result condensation of moisture. So a filter online back flushing should be equipped in this part.
The filters to be used: 1, Filter is used to ensure the stability of system and reduce the maintenance
2, Filtration Grade: usually 2 or 3 micron
For PM emission control in high temperature exhaust streams, such as fuel oil boilers, usual dedusters such as bag filters are very maintenance demanding. Particularly, diesel and fuel particulates are very sticky and clog to filter elements, unless protection reagents are used. Flue gas cooling is also needed in front of the filter when temperatures are higher than 200 ºC. On the other hand, regular cyclones and multicyclones are frequently not able to reduce emissions to present emission limits.
CTP systems can be found in every leading production company: thanks to the experience and the expertise developed in partnership with our customers for processes with inconsistent waste gas volumes; varying concentrations of organic components; gases contaminated with aerosols. CTP has installed systems for waste gas streams ranging from 1,000 to 200,000 Nm³/h. CTP supplies this industry with mainly catalytic systems, regenerative thermal oxidisers (RTO) and adsorbers. As the flue gases in this industry are...
Application: PPS (Ryton) Filter Bags are widely used in coal-fired boilers, waste incinerators, coking furnaces, kiln furnaces,Biomass Furnace ,chemical dry process of flue gas cleaning processes, also using, carbon black, powder collection, pneumatic conveying, cement industry, and more. When due to chemical attack and hydrolysis causes, Aramid cannot be used, PPS (Ryton) Filter Bag can be substituted.

teel and ferrous alloys production happens in industrial manufacturing processes which involve high temperature exhaust streams, often at more than 900 ºC. Typically, the gas flows into a gas conditioning tower to cool down to approximately 200 ºC, before entering into an ESP. These flue gases from steel or ferrous alloys kilns are also very maintenance demanding for bag filters and the very small size of the particles limit the use of usual dedusters such as regular cyclones and multicyclones as...
