Evaluation of Low-Emission Coal Burner Technology on Industrial Boilers. Project Summary

摘要

The Distributed Mixing Burner (DMB) is a low-NOx pulverized-coal burner for wall-fired boiler applications. The burner operates under reducing conditions in the primary flame zone to minimize NOx emissions while an overall oxidizing environment is maintained in the furnace to minimize slagging and corrosion. The operation is accomplished by using air ports around the burner throat to provide staged combustion conditions at each individual burner. The report gives results of a field evaluation of the DMB on a 98 kg/hr (215,000 lb/hr) steaming capacity, four-burner, front-wall-fired boiler.
