The present situation of desulfurization and dust removal equipment of coal fried boiler in Shenyang is analyzed.

Simply wet constructed integrated equipment of dust removal and desulfurization in application of 220t/h pulverized coal boiler;

The problem of scale in the pipe line of circulating water in wet dust removal and desulfurization system in Beijing region was analyzed and the accumulation of Ca2+and SO 2- 4 was found to be the main cause for scale formation.

Experimental data in the engineering practice of wet dedusting and desulfurization was processed,and relations among all the factors were found by fast calculation and optimization of Excel,which could solve the complex calculation and optimization problem.

Based on an example of dedusting and desulfurization of the flue from coal-fired bolilers in the Yun-Gui Plateau,the paper analyzed the problems that should have been paid attention in technical designing,and introduced the technology of dedusting and desulfurization by wet cyclone process

Improved swirl plate FGD and dust collection technology using four-stage lye spraying to increase gas-liquid absorption capability and improve desulfurization and dust collection efficiency is introduced.

Methods and ways of economic operation of the dust removing facilities are discussed.
