Two-Stage Combustion

Two-Stage Combustion

 

a method of burning fuels that have a low combustion reaction, such as anthracite. Some of the air required for combustion is introduced into the furnace not through the primary burners but through supplementary nozzles located 1.5–2 m above the burners. With this method the stream of coal dust and air is reduced; consequently, the heating of the stream by the flue gases is accelerated, and the conditions of ignition are improved. The supplementary air is carried to the torch in a zone where burning has already developed.

Owing to two-stage combustion (to be discussed later), two combustion durations are defined and identified in this work.
Specific design upgrades were made to the fuel injectors to optimize the combustion process, which features a two-stage combustion event instead of a single-injection event, further avoiding harsh, sudden and loud combustion.
