Abstract
An oven which has a floor, a side wall extending upwardly therefrom to define a combustion chamber, and a top having an opening for combustion gases, a fuel support member mounted in a lower part of the combustion chamber, the fuel support member having a raised central portion with a downwardly and outwardly sloping top surface extending therefrom, and means for supplying fuel to the fuel support member. The oven includes an arrangement for providing primary air to the fuel on the fuel support member and for providing secondary air to an upper portion of the combustion chamber, the secondary air being arranged to impart a cyclonic motion to the combustion gases.
Claims12
An oven comprising a floor, an oven side wall extending upwardly therefrom to define a combustion chamber, and a top having an opening for combustion gases;
- a fuel support member for receiving fuel mounted in a lower part of said combustion chamber, said fuel support member having a raised central portion, a downwardly and outwardly sloping top surface extending from said raised central portion;
- means for feeding fuel to said fuel support member;
- means for providing primary air to said fuel on said fuel support member;
- and
- means for providing secondary air to an upper portion of said combustion chamber, said means for providing secondary air being arranged to impart a cyclonic motion to said combustion gases.
A method of providing complete combustion of a fuel and generating combustion gases suitable for drying a product, the method comprising the steps of providing an oven having a floor, an oven side wall extending upwardly from said floor to define a combustion chamber, and a top, the oven having a fuel support member mounted in a lower part of said combustion chamber, said fuel support member having a raised central portion and downwardly and outwardly sloping top surface extending from said raised central portion, and supplying primary air to fuel mounted on said fuel support member, providing secondary air in a cyclonic configuration to an upper portion of said combustion chamber.
