OSTI ID:6856484
The report describes the first phase development of an Advanced Natural Gas Fired Cyclonic Burner/Boiler, (CB/B), for the 250 hp to 2500 hp industrial boiler market. Cyclonic combustion of natural gas is accomplished by injecting natural gas and combustion air tangentially, at high velocity, into a cylindrical combustion chamber. The high tangential velocity of cyclonic combustion results in the swirling combustion flow pattern that enhances the heat transfer to the boiler. The cyclonic combustion also creates high internal recirculation which serves to reduce flame temperature, improve air/fuel mixing and reduce combustion emissions. The CB/B concept, consisting of a low NOx high intensity two-stage cyclonic burner, a watertube wall furnace and a firetube type steam drum, is shown to be technically feasible and economically viable. A 2.5 MMBtu/hr pilot scale two-stage cyclonic burner was successfully tested and achieved NOx of less than 25 ppm with 5% excess air. A 250 hp (10 MMBtu/hr) CB/B Industrial Prototype unit has been designed to achieve 85% efficiency.
