Boiler Fuel - an overview | ScienceDirect Topics

Fuel flow control. The primary boiler fuels are coal, oil, and gas. Oil and gas involve the simplest controls, since they can be measured easily and flow is regulated by a control valve in the fuel line. On the other hand, since coal is an unmeasured fuel, the control system is open-loop, in which a fuel demand signal positions a coal-feeding

25-02-2004 · Modulating control improves boiler operation by monitoring the steam or hot-water line to produce a continuous control signal that determines the fuel input. Reductions in steam pressure or water temperature lead to an increase in firing rate. The advantages of burner modulation for combustion control include:

Most NOx control technologies for industrial boilers, with inputs less than 100 MMBtu/hr, reduce thermal NOx and have little affect on fuel NOx. Fuel NOx is most economically reduced in commercial and industrial boilers by switching to cleaner fuels (fuels containing less fuel-bound nitrogen), if available.
