Title:
LOW NITROGEN-SOURCE PURE OXYGEN COMBUSTION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/104649
Kind Code:
A1
Abstract:
A low nitrogen-source pure oxygen combustion method. The method employs a low-nitrogen fuel, employs pure oxygen as a combustion supporting gas, separately delivers the pure oxygen and the low-nitrogen fuel, controls the ratio of the pure oxygen/the low-nitrogen fuel, performs four-corner tangential pure oxygen combustion in a combustion chamber (3), and implements deep and complete combustion of the low-nitrogen fuel, thus reducing the emission concentration of CO and NOx. The method implements pre-combustion nitrogen source reduction, eliminates or reduces NOx from the source, increases the thermal energy conversion efficiency for the fuel, obviates the need for flue gas denitration equipment, and implements a NOx combustion emission concentration of 5mg/m3-100mg/m3, a CO combustion emission concentration of 50mg/m3-500mg/m3, and a combustion efficiency of 95% or more.
