Automatic high technology pellet boiler specifically for peat and biomass
The ultimate objective of this work was the establishment of a pellet fuel system, which could enable peat and biomass (straw or wood) pellets to replace distillate oil as central heating fuel. Although these fuels have been significantly less expensive than distillate oil on an energy basis for a considerable time they have never seriously challenged oil for three reasons. Firstly oil-fired central heating boilers operate at far higher efficiencies than their solid-fuel competitors, secondly they are highly controllable in that the user can control both the temperature of the heated space and the periods during which they are heated. Finally oil is cleaner and more convenient than solid fuel, it leaves no ash and being a liquid it can be delivered through pipes and stored in tanks. The contractors had two immediate objectives, firstly the development of an automatic, highly controllable, clean and convenient pellet-fired central heating boiler which operates at high efficiency over a wide range of output, and secondly to devise the microprocessor-based control system for this boiler. The plan was to package this fully automatic pellet-boiler together with existing pellet-handling devices thereby establishing the pellet fuel system, through which peat and biomass pellets would provide controllable, convenient, and non-polluting central heating at a cost well below that of oil-fired boilers.
