Staged combustion - Wikipedia

Air staging, or two-stage combustion, is generally described as the introduction of over-fire air into a boiler or furnace. Staging the air in the burner (internal air staging) is generally a design feature of low NO x burners.. Furnace over-fire air (OFA) technology requires the introduction of combustion air to then be separated into primary and secondary flow sections.

Development of the Radially Stratified Flame Core Low NOx

Research and development of the low NO x radially stratified flame core (RSFC) burner is followed from its fundamental concept through prototype burner design, pilot scale experiments at M.I.T. and scale-up and commercial design by ABB-CE (now ALSTOM Power) to applications in industrial and utility plant boilers. The principle that turbulence can be significantly damped in a rotating flow

5. Biomass Conversion Technologies

Heat is transferred from the fire and combustion gases to water tubes on the walls of the boiler. Modern mechanical stokers consist of four elements, 1) a fuel admission system, 2) a stationary or moving grate assembly that supports the burning fuel and provides a pathway for the primary

Challenges and Advantages of Stratified Combustion in

stratified combustion increases fuel efficiency. However, it also tends to produce high particulate emissions and can reduce combustion stability. These problems mainly occur because stratified combustion involves a complex mixing process that generates a heterogeneous air/fuel mixture with both rich and lean regions.

Greenhouse Vegetable Production

Shell boilers may be defined as those boilers in which the heat transfer surfaces are all contained within a steel shell. Shell boilers may also be referred to as fire tube or smoke tube boilers because the products of combustion pass through the boiler tubes, which in turn transfer heat to the surrounding boiler
