Premix burnera device that mixes fuel gas with air before either enters the burner tip, p. 297. Radiant tubestubes containing boiler feedwater that are heated by radiant heat from the burners and boiled to form steam that is returned to the steam drum, p. 297. Raw gas burnera burner in which gas has not been premixed with air, p. 297.
in boilers, but the most common types of fuel include coal, oil, and natural gas. During the combustion process, oxygen reacts with carbon, hydrogen, and other elements in the fuel to produce a flame and hot combustion gases. As these gases are drawn through the boiler, they cool as heat is transferred to water.
Boiler Classification and Application - CED Engineering
At full capacity a boiler of this size converts 3 000 litres of fuel oil or a corresponding amount of natural gas to thermal or process heat every hour. This would be sufﬁcient to heat more than 2 000 houses. Because of the huge volume of water and the multi-stage lead-through of
