MAPLE SYRUP EVAPORATOR WITH BIOMASS BURNER

摘要

A burner using biomass combustibles, namely pellet fuel, for a maple syrup evaporator. Compared to wood or oil burning heat sources, pellet fuel is less costly, burns more efficiently and generates the heat necessary to properly evaporate maple sap. The burner includes a burn pit defining a plurality of holes for allowing air to communicate between a combustion chamber and a primary air plenum formed between a base and an underside of the burn pit. An air supply conduit supplies air supply to the primary air plenum. A fuel conduit in communication with the combustion chamber supplies the pellet fuel for combustion within said burn pit. A secondary plenum in pneumatic communication with the primary air plenum receives and cools a portion of the primary air supply. A plurality of injectors in communication with the secondary plenum inject the cooled air into the combustion chamber.
