    摘要： A multi-stage heating apparatus having a first stage combustion chamber, a second stage combustion chamber, a primary porous matrix chamber disposed between the first and second stage combustion chambers, a secondary porous matrix chamber, heat exchanger tubes for transfer of heat from the combustion products to a working fluid, a recirculation device for recirculating combustion products in the first and second stage combustion chambers to the root of flames therein. A mixture of fuel and primary oxidant is introduced into the first stage combustion chamber, and the products of combustion therein are conveyed to the porous matrix chamber disposed between the first and second stage combustion chambers. After undergoing intensive heat transfer in the porous matrix chamber, the cooler products of combustion flow into the second stage combustion chamber forming additional products of combustion. The products of combustion then flow to a second porous matrix chamber in which they undergo further intensive heat transfer. From there, the products of combustion pass through an economizer for preheating a working fluid and through a condenser for removing moisture in the combustion products prior to being exhausted.

    摘要： In a gas burner for introducing a fuel/air mixture into a combustion chamber, a tube is provided for introducing a source of primary air into a core portion of the fuel air mixture. The resulting secondary flame that is produced within the primary flame causes a reduction of NOX gases, which can be attributed to the dispersion of combustion byproducts within the primary flame. In one embodiment, the air supply tube enters the area of the fuel air mixture radially and then turns and extends axially along an extended axis of the burner.

    摘要： A method of operating a solid fuel-fired furnace having a plurality of windboxes each having a plurality of compartments through which fuel and air are introduced into the furnace and a fuel and air arrangement operated in accordance with the method are provided. Solid fuel is fed into the furnace and primary air and fuel are fed through the same compartments into the furnace in a direction tangential to a first imaginary circle generally located in the center of the furnace so as to interact with the fuel fed into the furnace so as to create a rotating fireball. Overfire air and offset air are also supplied into the furnace, the offset air being that portion of the air supplied to the furnace so as to support a second imaginary circle concentric to, and having a larger diameter than, the first imaginary circle. The total air supplied into the furnace is thus composed of primary air, additional combustion supporting air, overfire air, and offset air supplied in accordance with a prescribed relationship between the components of the supplied air.
