Fluidized bed combustion - Wikipedia

Working Principle. Both gas and oil fired boilers use controlled combustion of the fuel to heat water. The key boiler components involved in this process are the burner, combustion chamber, heat exchanger, and controls. The burner mixes the fuel and oxygen together and, with the assistance of an ignition device, provides a platform for combustion. This combustion takes place in the combustion chamber, and the …

In its most simple form, the air flow SP is the greater of the boiler master and the actual fuel flow PV (%) and the fuel flow SP is the lesser of the boiler master and the actual air flow PV (%, after it is run through the FAR PWC and O 2-trimmed). This forces air to lead on firing rate increases, and fuel to lead on decreases, and ensures that if the system ever runs out of air, it will never add too much fuel.

Ultra Low-sulfur grade available. Average of 135,000 BTUs per gallon. Fuel Oil No.-2: A slightly heavier distillate with a maximum distillation temperature of 675 F. Use is for mechanically atomizing type burners and where sediment in fuel and preheating are prohibited or limited. This is the general fuel for automatic oil-fired heating equipment.

fuel and are not affected by boiler size, burner design, or grade of fuel being fired. On average, more than 95 percent of the fuel sulfur is converted to SO2, about 1 to 5 percent is further oxidized to sulfur trioxide (SO3), and 1 to 3 percent is emitted as sulfate particulate. SO3 readily reacts with water vapor (both in the
