New biomass technologies
To obtain cost-efficient and environmental-friendly heat supply focus is put on district heating. Requirements to cost-effective biomass combustion technologies for district heating are: 1) High energy efficiency, 2) Compact plants, 3) Fuel flexibility so a wide range of fuels can be used, 4) Effective, simple, reliable and economical gas cleaning systems, 5) Low maintenance costs, 6) Low environmental impact. The project concerns verifying a new multifuel oven, designed and patented by Dall Energy, that enable future biomass plants to fulfil all the requirements. Targets of the Multifuel oven: a) Multifuel - 0-60% moisture, - Wood, kernels, etc.; b) Low NOx; c)Low CO; d) Low O2; e) Low carbon in ash; f) No moving parts in varm/hot zones; g) Simple ash system; h) Compact; i) Easy to manufacture, transport and install
In the project, Dall Energy developed a multi-fuel furnace jointly with SEM Staalindustri. The principle combines gasification and incineration, a process entailing several advantages: The plant becomes cheaper to build, hazardous substance emission decreases, and the output can be reduced to about 10%, thus saving the costs of a ''summer boiler''. The furnace was tested for the first time in December 2009, the results being very promising. Thus, emissions of NOX, CO and dust particles proved much lower than from a conventional grate-fired plant, and operation remains stable even at 10% output. (Energy 10)
