ABSTRACT:
A burner capable of burning low pressure combustible gas with minimum pollutant emissions. The gas is preheated to hydrocarbon cracking temperatures in a heat exchanger located directly within an elongated water jacketed combustion chamber of the burner. The heated, expanding and rapidly flowing gas from the heat exchanger passes through a nozzle to further accelerate the gas for passage into an air intake system together with aspirated air. The nozzle and intake system are adjustable to meter in proper amounts of gas and air for a stoichiometric mixture. The gas/air mixture is laterally directed into the combustion chamber to induce turbulence and continued mixing for optimum ignition and burning. The resulting heated gases are useful in various end applications, such as in steam generating boilers. The burner is also adapted to inject steam into the preheated gas or into the intake system or into both to increase mass flow of air and to promote low pollutant emissions.
