Impact of waste fuels (virgin/waste wood, mixed biofuel (peat, bark, wood chips) industrial, household, mixed waste fuel) and incineration technologies on partitioning and leaching behavior of trace elements has been investigated. Study included 4 grate fired and 9 fluidized boilers. Results showed that mixed waste incineration mostly caused increased transfer of trace elements to fly ash; part...

In serial cleaners, stationary grates with a circular cross section are installed to remove foreign matter. To increase the cleaning effect, an attempt was made activate working surfaces of grate bars polymer coatings. Although they increased did not find industrial application. recent years, imparting mobility has been used improve performance. This is carried out in two ways: which receives m...

The differential equation, obtained as a result of the theoretical study movement bare seed on surface grate saw gin, made it possible to determine trajectory seed. rib is one main working bodies gin. It serves for free passage blades through into chamber, withdrawal fiber caught teeth after separating from A number studies have been carried out improve elements purpose research create possibil...

A mathematical model was developed of the drying, volatilization, and combustion phenomena on the packed bed of solid wastes on a moving grate. Gasesolid flow and the heterogeneous chemical reactions were considered. Since experimental work in this area of study is very difficult and costly, the development of such a model is very important. The gas phase turbulence was modeled using keε turbul...

Establishing an appropriate NOX production and decomposition model is of practical significance to the grate firing of biomass fuel. This study used the CHEMKIN software package to simulate the combustion process of biomass pyrolysis and char combustion. Through rate of production (ROP) analysis and simplification based on GRI-Mech3.0, the 15-step reaction mechanism of volatile-N converting int...

An integrated installation for treatment of municipal solid waste and comparable waste from industrial origin is described. It consists of three grate furnace lines with flue gas treatment by half-wet scrubbing followed by wet scrubbing, and an installation for wet treatment of bottom ash. It is demonstrated that this integrated installation combines high recovery of energy (40.8% net) with hig...
