Heater and burner assembly therefor
This patent describes a heater comprising: a housing defining a combustion chamber and adapted to permit radiation of heat produced by combustion in the chamber. The combustion chamber has an exhaust outlet, and the housing includes a combustion air inlet passageway; a fuel reservoir disposed in the housing below the combustion chamber, for containing a fuel supply; and a burner disposed in the combustion chamber and comprising a combustion air inlet tube disposed in a generally upright position above the fuel reservoir and having an air outlet at its upper end and an air inlet at its lower end, the air inlet communicating with the combustion air inlet passageway. The burner has a wick in the form of a mass of non-combustible fibres wrapped around an annular support surrounding the air outlet and defining a combustion zone and a means constraining the fibres to extend downwardly from the support and into the fuel reservoir for conveying liquid fuel to the combustion zone. The burner also has means for delivering secondary combustion air to the combustion zone externally of the wick, from the combustion air inlet passageway. The means constrains the fibres of the burner comprising a series of tubes extending downwardly from positions adjacent the air outlet of the combustion air inlet tube and into the fuel reservoir.
