Recommended application field: The installation can be used by municipalities or landfill operators for MSW utilization. As producer gas is of high guality the unit can be eguipped with gas engine for power production.

Advantages over analogues: The proposed gasification tehnology has advantages over other types of gasifiers as well as over other thermochemical processes for MSW treatment such as combustion and pyrolysis, namely: - Low formation of dioxins and furans due to optimal construction of the gasifier and combustion chamber; - comparatively simple gas cleaning system; - low negative impact upon ervironment; - compacting effect from gasification is much more than that from pyrolysis. Unburned charcoal remains after gasification; - gasification is a less power-consuming process than pyrolysis; - as gasification takes placeunder limited amount of oxygen, formation of dioxsins is much less intensive than during direct combustion of MSW; - due to lower temperature during gasification as against combustion, of NOx is also much less intensive.

The development stage readiness: tested in laboratory condition

Description of the development:
()
Environmentally friendly gasification technology for processing of municipal solid waste (MSW) is proposed. The technology allows to treat MSW effectively and to obtain medium-calorific producer gas with minimal negative impact upon environment. Twin fluid bed gasifier consists of two fluid bed reactors - gasifier itself and combustion chamber - connected with each other by a chute. Steam gasification takes place in the gasifier; sand is an inert material of the bed. Sand is heated in combustion chamber at the expense of char coming from gasifier through chute. Heated sand goes back to gasifier. The construction of the unit is suitable for further scaling up so that the technology is brought to demonstration level and then to commercial application.
