Technical advice on boiler combustion control

2020-9-11 · A typical natural-gas-fired boiler will operate with combustibles concentrations less than 50 parts per million (ppm), while a coal-fired boiler may operate with combustibles concentrations greater than 200 ppm. Generally, combustibles concentrations less than 100 ppm are considered negligible in terms of efficiency impact.
