Controlling the Air-Fuel Ratio in Combustion Furnace

The CX1000/CX2000 calculates the air fuel ratio with an SP computation function that maintains a uniform amount of air and gas supplied. The CX improves fuel efficiency by controlling the combustion such that it uses an air fuel ratio based on the precise air mass flow, and contributes to stability in quality and reduction of operating costs.

BOILER AND HEATER OPERATIONAL CONTROL

2020-3-12 · Controlling excess air is the most important tool for managing the energy efficiency and atmospheric emissions of a boiler system. It is important to keep in mind that the air-to-fuel ratio is based on mass, not volume. The mass of air supplied to the mass of fuel being used (e.g. on a kilogram-to-kilogram basis) must be controlled.

Calculation of the Excess Air of Combustion Proces

The amount of air needed to completely burn a certain amount of fuel can be calculated theoretically using the basic principles of stoichiometry (see following article). In other words, if every fuel molecule precisely contact with oxygen in the air and reacted, then the entire fuel must be burned, and there will not be a Continue reading "Calculation of the Excess Air of Combustion Process"

Boiler Efficiency and Combustion | Spirax Sar

Accurate control of the amount of air is essential to boiler efficiency: Too much air will cool the furnace, and carry away useful heat. Too little air and combustion will be incomplete, unburned fuel will be carried over and smoke may be produced. In practice, however, there are a number of difficulties in achieving perfect (stoichiometric
