Exhaust gas treatment system performance test

     Inheriting more than 40 years of experience in thermal power plant’s exhaust gas treatment system performance test, Chugai Technos can perform the performance testing of all systems in coal power plants with a system of instruments and sampling equipment to ensure almost of present thermal power plants.
◆ Environmental services at the plant:
  •  During plant commissioning:
    • Supporting plant commissioning;
    • Monitoring temperature, pressure, flow rate, dust, NOx, CO, SO2, O2, CO, CO2, to confirm combustion efficiency of the boiler;
    • Analyzing coal, slag and fly ash;
    • Investigating the NH3 distribution of SCR system;
    • Analyzing absorption solution (slurry) of FGD system.
    • Monitoring stack gas.
  •  Exhaust gas treatment system performance testing services:
    • Performance testing for boiler combustion, including air balance test, coal fineness test;
    • Performance testing for De-NOx Selective Catalytic Reduction (SCR) system, including AIG Tuning;

◆ Investigation and analysis of special contents in flue gas

     Based on the experiences and achievements gained in the process of exhaust gas monitoring, performance testing, and commissioning at plants, Chugai Technos carries out investigation and analysis to propose optimal methods for sampling and analysing the special ingredients in exhaust gas.

  • Investigation of pollutants not included in emissions regulations;
  • Investigation of SO3 in exhaust gas,
  • Investigation of total dust, particle size;
  • Investigation of mist in exhaust gas,
  • Investigation of exhaust gas in various plant.
