Combustion system
摘要:
A combustion system includes a primary combustion chamber divided into left and right sides by fuel-retaining standards defining a canyon or void extending into a secondary combustion chamber is provided. The floor of the primary combustion chamber and the fuel-retaining standards direct the burning solid fuel toward the lower part of the canyon, while at the same time retaining the non-burning solid fuel on either side of the fuel-retaining standards. The combustion system further includes an air delivery system having a lower air tube supplying high and low velocity air and an upper air tube. The lower air tube is positioned proximate to a firebox floor, while the upper air tube is positioned within the secondary chamber. Automatic air setting mechanisms are provided so that proper air settings can be maintained during various phases of a fire. The combustion system further includes a loading door having openings and a bypass system preventing the loading door from being fully closed unless the bypass is in the completely closed position. The secondary combustion chamber includes at least fuel protecting baffles and a secondary combustion chamber ceiling which extends partially over the entire length of the secondary combustion chamber or includes openings. A catalyst mounting system which minimizes canning and masking and a radiant catalyst heating system are also provided.
