Impact of Primary Air Separation in a Grate Furnace on the Resulting Combustion Products

When burning fuel in grate furnaces, supplying the right amount of air to them is as important method supply. In a furnace with fixed grate, supply primary determined by distribution supplied stream over time, and movable said involves along active length grate. The need account for attributable complex processes that occur during combustion process. paper describes experimental studies aimed at determining influence on emission CO2, CO, SO2, NOx, content combustible parts slag. all cases, total process well other control parameters was identical, only different. proposes use generalized function describe air, defined its demand relative time R remains until maximum obtained. quantity accepted value ranging from 1/6 2/3. With rise R, emissions SO2 increased 53%, 125%, 27%, respectively, NOx share combustibles slag decreased 12% 79%, respectively.
