Performance and Specifications
The Delta-NOx burner achieves NOx emissions between 0.06 and 0.1 lbs/mmBtu when firing natural gas, without the need for flue gas recirculation (FGR). It supports a capacity range of 20 to 380 mmBtu/hr and is compatible with a wide range of gaseous and liquid fuels. The burner features a venturi design for superior air distribution and reduced pressure drop, contributing to its energy efficiency and low operating costs.

Application
A hazardous waste incineration facility required an efficient replacement burner for its watertube boiler. The existing burner had limited fan capacity and high CO emissions. COEN's Delta-NOx burner was installed, reusing existing components to reduce retrofit costs, and included additional components and services such as the throat assembly, control valve, and turnkey installation.

Results
The installation of the Delta-NOx burner resulted in significant improvements: NOx emissions averaged 0.066 lbs/mmBtu, representing a 60% reduction; CO emissions averaged 0.033 lbs/mmBtu, an 85% reduction; steam capacity increased by 20% with the existing air fan; and fan operating horsepower was reduced by 10%, eliminating the high costs associated with FGR. The burner was set for automatic operation within one day.
