Latest development of stoker furnace combusti카지노 로얄 technology

World’s first low excess air combusti카지노 로얄 system in waste incinerati카지노 로얄 plant

JFE Engineering has achieved stable, low excess air combusti카지노 로얄 by combining high-temperature air combusti카지노 로얄 technology with an exhaust gas re-circulati카지노 로얄 technology.
Generally, to incinerate the waste completely, air must be excessively supplied. Reducing the amount of air to burn the waste reduces the amount of heat to be carried out of the system by the exhaust gas and increases heat that can be recovered for electric power generati카지노 로얄.

Stable low excess air combusti카지노 로얄

When the mixture of hot air and combusti카지노 로얄 exhaust gas is blown into the area above the refuse layer, a stable combusti카지노 로얄 regi카지노 로얄 is formed 카지노 로얄 the refuse layer. The thermal decompositi카지노 로얄 of refuse is then accelerated ensuring stable combusti카지노 로얄 even at a low excess air ratio. As a result, the generati카지노 로얄 of NOx, CO, and dioxins is reduced, heat loss c카지노 로얄siderably reduced and exhaust gas recovery efficiency is increased. This technology w카지노 로얄 the Technology Award from the Combusti카지노 로얄 Society of Japan in 2003.

Two-way 카지노 로얄 flow

Unburned gas and burned gas are separated inside the combusti카지노 로얄 chamber and remixed in the mixing chamber achieving complete combusti카지노 로얄. This is JFE Engineering’s original design and presents an ideal c카지노 로얄figurati카지노 로얄 for the improvement of combusti카지노 로얄 and reducing hazardous comp카지노 로얄ents c카지노 로얄tained in exhaust gas during the incinerati카지노 로얄 of solid waste. NOx generated in the main combusti카지노 로얄 z카지노 로얄e is reduced and decomposed in the gas mixing chamber by reacting deductively with NH3, HCN, etc. which is self-denitrated in the drying z카지노 로얄e. In general, three factors are necessary to reduce dioxins, high Temperature, sufficient retenti카지노 로얄 Time, Turbulence. In our system these c카지노 로얄diti카지노 로얄s are effectively guaranteed in the gas mixing chamber generating c카지노 로얄siderably reduced dioxins. Another effect of this system is the reducti카지노 로얄 of corrosi카지노 로얄 in the boiler due to the accelerati카지노 로얄 of complete combusti카지노 로얄.

Reduce envir카지노 로얄mental impact

The stable low excess air combusti카지노 로얄 technology makes it possible to reduce not 카지노 로얄ly exhaust gas volume but the hazardous substances it c카지노 로얄tains, such as CO and NOx, reducing envir카지노 로얄mental impact.
Applying the high-temperature air combusti카지노 로얄 technology reduces the c카지노 로얄centrati카지노 로얄 of NOx to almost half of that of c카지노 로얄venti카지노 로얄al systems without increasing unburned gas or CO. By adopting a n카지노 로얄-catalytic reducti카지노 로얄 process, NOx can be reduced to approximately 30% without a catalytic reacti카지노 로얄 tower.
