<p>An apparatus and method for controlling wall temperature of a coal combustion system, having a primary combustion chamber (10) connected and in pressurized communication with a secondary combustion chamber (30), are disclosed. Optionally, the coal combustion system has a separation chamber (20) disposed between the primary combustion chamber and the secondary combustion chamber. A gas, such as steam or compressed air, flows through internal gas flow passages within the wall (16, 26, 36) of at least one of the combustion system components. The flow of gas removes heat from the refractory material of the wall portion adjacent to the internal passages. Controlling wall temperature in this manner enhances slag collection and removal within the combustion system.</p> |
