Abstract

A combustion chamber for burning low BTU fuel comprising a generally cylindrical casing having adjacent outer and inner annular spaces defined by outer, intermediate and inner walls, the spaces intercommunicating at the downstream end of the casing thereby providing a U-shaped flow path. The outer annular space traverses the entire length of the casing while the inner space extends to the approximate mid-point of the casing, thereby communicating with internally disposed combustion units. In operation, fuel as coolant is fed to the outer space at the upstream end, traverses the U-shaped flow-path thus making a double pass around the combustion zone of the combustion chamber and thence to the combustion units for ignition. Improved cooling is obtained.
