Sulfur removal at high temperature during coal combustion

Jan 01, 2003 · In-furnace desulfurization is a competitive technology for controlling the SO 2 pollutants derived from coal combustion, due to the low capital and operating costs contrasted to flue gas desulfurization techniques. This paper focuses on sulfur removal processes in IGF and PCFB with high flame temperatures of 1200–1600 °C, which have much lower desulfurization efficiencies than those …

How to Desulfurize Coal Fired Boiler

Liming 13:31:21. There are many desulphurization methods for coal fired boilers, but there are three kinds of commonly methods, pre-combustion desulfurization, desulphurization in the furnace and flue gas desulphurization, and the most widely used is desulfurization in the furnace. ZBG mainly adopts furnace desulphurization instead of flue gas desulfurization, because it is selected from the cost …

and so on. Moreover, high-sulfur coal usually contains high content of hazardous trace elements (Dai et al., 2007). Ash lowers the combustion efficiency of boilers and causes other deleterious effect. Ash handling and disposal of ash are also problems. Therefore, it is necessary to remove the mineral matter and sulfur from coal prior to its
