Based on current status of desulfurization calcium-sulfur ratio on active 150MW CFB boiler running poor economically, the actual influencing factors of the low desulfurization efficiency are studied combined with the desulfurization mechanism. In a typical load of 150MW CFB boiler, the degree of key factors influence on calcium-sulfur ratio is analyzed. On this basis, high efficiency technologies for improving the desulfurization efficiency and reducing calcium-sulfur ratio are proposed one by one for the influencing factors, and the application of technology is implemented on 150MW CFB boiler. The experiment is arranged to test desulfurization calcium-sulfur ratio of the boiler furnace before and after the implementation of the technology. The results show that the comprehensive operating calcium-sulfur ratio of the unit is reduced by 70% after the the application, and the technology has a good effect on significantly reducing calcium-sulfur ratio.
