Abstract:
Within the IEA Bioenergy Task32 "Biomass Combustion and Co¬firing" a survey on the present state¬ of¬the¬art of particle precipitation devices for residential biomass combustion systems (nominal boiler capacity <50 kW) in the Task32 member countries has been performed. This paper gives an overview on the present state¬ of¬ the¬ art of small¬ scale particle precipitation devices available or under development and an assessment regarding their applicability, availability and technical performance. A literature survey as well as data available from filter manufacturers, data from national projects of the Task32 member countries and data from the ongoing ERANET project "Future Biotec", formed the basis of this survey. The survey involved the evaluation of 12 electrostatic precipitators, 2 catalytic converters, 2 ceramic filters, 3 condensing heat exchangers and one additional device. The ESP technology seems to be the most promising technological approach for small¬scale biomass combustion. With the ESPs generally mean total dust precipitation efficiencies of 50 to 85% can be achieved. Up to now no promising results have been achieved with catalytic converters for wood boilers/stoves. A specially developed high temperature condensing heat exchanger has potential, but needs further research on practical needs. The dust precipitation efficiency of conventional condensing heat exchangers is rather low.
