Wall Mounted Flue Gas Analyzer For Efficient Combustion


The new Optimiser is a wall mounted Flue gas analyzer that monitors stack emissions for efficient combustion of either Natural Gas, Coke, Propane, Butane, Light Oil, or Heavy Oil. Optimiser works by using two separate probes to measure the temperature and Oxygen content. From these measurements, it calculates the Carbon Dioxide content and the process efficiency.

Oxygen content is a very sensitive indicator of boiler efficiency. Too little Oxygen means that insufficient air has been used and combustion is incomplete leading to dirty and polluting exhausts. If too much air is used, then heat is wasted and running costs escalate. If the air is managed, then these problems may be eliminated.

Optimiser offers digital display and is factory set to your specifications. However, users may choose an optional remote keypad to adjust any settings and perform calibration. Industry standard 4-20 mA outputs are included to allow integration to building management systems. An additional RS 232 link allows all parameters to be transmitted to a PC.
