Burt’s Greenhouses (Alex English) converted from an oil-fired to a wood biomass boiler system to heat their greenhouses. A special augur was designed to feed wood into the boiler. Innovative boiler modifications were made by the company to improve combustion and decrease pollution. The boiler also produces bio-char which is used by the business. Alex English is very familiar with the technical and practical challenges in the small-scale commercial use of bio-mass energy.
