Embodiment Construction

[0012]The present invention is illustrated in further details by the following non-limiting examples.

[0013]Now referring to FIG. 1, there is provided an evaporator for the evaporation of maple sap in the production of maple syrup generally referred to using the reference numeral 10. The evaporator comprises a maple sap evaporating section 12 and a maple syrup forming section 14 both illustratively comprising horizontally extending pans 16, which are shown in FIG. 2, provided with partitions in which maple sap travels. The evaporator 10 further comprises a hood as in 18 for each section 12, 14 and vapour outlets as in 20 for directing the water vapour evaporated from the sap to atmosphere.

[0014]Now referring to FIG. 2, in addition to FIG. 1, extending beneath the maple sap evaporating section 12 and the maple syrup forming section 14 is a heating housing 22 comprising a heating chamber 24 for exposing heated air 26 and flames 28 to the undersides of the horizontally extending pans 16...

Abstract

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.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a biomass burner. In particular, the present invention relates to a biomass burner comprising a fuel and air supply system to provide a high efficiency burner for a maple syrup evaporator.BACKGROUND OF THE INVENTION[0002]Maple syrup evaporators used for evaporating water contained in maple sap generally employ wood or oil burning heat sources for causing evaporation. One drawback of such burners is the high cost of the wood or oil fuel, their energy conversion inefficiencies, and environment impacts associated with the pollutants emitted during combustion of the fuel such as particulate matter, Nitrogen Oxide (NOx) and Sulphur Dioxide (SOx).[0003]What is therefore needed, and one aspect of the present invention, is a burner for maple sap evaporators that uses biomass combustibles which are less costly, burn more efficiently and which generate the heat necessary to properly evaporate maple sap. Additionally, what is needed ...
