CFB: Technology of the Future? Power Engineering
Babcock & Wilcox will design and deliver a 360,000 lb/hr, 38.5 MW CFB boiler that will burn Powder River Basin coal as part of the Authority’s plan to repower its Lamar Light and Power plant.With the stringent emission regulation taking effect, it is difficult for the conventional desulfurization technology in circulating fluidized bed (CFB) boilers to meet the requirements of ultralow SO2 emission. Therefore, in this paper, the application of natural ultrafine limestone, with a Sauter mean diameter of less than 20 μm, was tested by Applications of Ultrafine Limestone Sorbents for the
