Model CCS Comet - Combustion Control System
Oxygen Measurement, Carbon monoxide extractive measurement with electrochemical cell, Temperature measurement, Semi-extractive approach with mounting directly to the stack, Easy installation, Simplicity of use.
The general approach is based on the principle that adequate internal alarm systems must ensure the reliability and safety of the analysis system and that the instrumentation is not damaged. If even a single component of the system has irregular operation, which may affect its safety or accuracy, the system design ensures that the suction pump is blocked and a contact and a light signal are activated; the “alarms” and the faults of the analyzers are transmitted to the data acquisition on a remote PC.
The systems can be designed by providing the possibility to sample the gas multiplexing from different sampling points (up to 4); by means of a PLC, stainless steel solenoid valves are activated. If it is necessary not to condense the combustion product, the solenoid valves are placed in stainless steel boxes heated to 180 °C.
It is possible to realize different types of communication systems between the analysis system and the plant supervision: more commonly, by means of a complete analogical hard wired digital wiring or through local networks (LAN) with OPC standard and Modbus TCP.
A wide range of complete analysis systems can be designed, produced and put into service. All systems are designed basing on the needs of the individual customer and the features of the plant to be monitored.
All systems are built in accordance with current international regulations (for example EN61010-1 for Europe and UL508A for USA).
FER Strumenti has designed an analysis system that performs the required measurements and uses the following modules:
- Oxygen measurement with zirconium oxide analyzer
- Measurement of carbon monoxide with electrochemical cell analyzer
- Flue gas temperature measurement
- 4-20 mA active outputs
Sample extraction probes with heated silicon carbide filter or steel filter. Filter cartridges with different degrees of retention are available and versions with electrical protection for ATEX zones 1 and 2. The probes can be supplied (in addition to the standard connection for the heated line) both with the backwash input and the dynamic calibration input.
Infrared multigas analyzers for the analysis of CO-NOx-SO2-CH4-CO2 mod. Enox II and double optical path – heated if needed – for the measurement of HCl and NH3.
Sample transport heated lines with temperature regulator with a length of up to 100 meters. Available also for zone 1 and 2 with up to 3 internal tubes.
Zirconium oxide extractive oxygen analyzers mod. E705.
Compressor or Peltier gas coolers with continuous condensate drain and stainless steel, Teflon or glass heat exchanger.
TOC flame ionization (FID) analyzers for the analysis of total hydrocarbons, available in 3 solutions.
Fine hot and cold filtration with condensation detector.
