Microprocessor Based Combustion Monitoring and Control Systems Utilizing in Situ Opacity, Oxygen and CO Measurement
MetadataShow full item record
A new hybrid combustion control system has been developed which combines the functions which have traditionally been performed by separate stand-alone measurement and control instruments into one low-cost integrated system. Complete O2 Trim Control Systems will soon be available starting at less than 6,000 dollars. By utilizing a high performance low-cost microprocessor, both measurement and control functions can now be performed simultaneously. The new systems will feature automatic calibration, self-diagnostics, field programmable memory, and improved operator interface. By measuring the products of combustion utilizing the latest In Situ Opacity, Oxygen, and CO Monitoring technology, the fuel air mixture ratio of industrial fuel burning equipment can be optimized to insure reduced fuel consumption end improved combustion efficiency. Typical fuel savings of 3 to 5 percent have been experienced on a wide variety of different types of fuel burning sources, including packaged boilers, incinerators, and process heaters.
