Furnaces, heaters, and boilers burn fuel to produce heat. Achieving an intelligent balance of fuel and air will provide the most efficient combustion and highest cost savings. Efficient combustion also reduces emission of pollutants such as nitric oxide (NO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and particulate matter.
Measuring the exhaust gas is an excellent way to optimize fuel and air input. A gas analyzer will enable you to measure the concentrations of various gases and adjust burners on a boiler to help achieve optimal combustion.
