Desulfuration through spraying calcium into the furnace is a generally recognized economic and suitable desulfuration method

the influences of the said method upon operating performance of the boiler in the process of its implementation

such as slagging in the furnace

heat surface contamination

abrasion of the heat transfer surface

combustion condition in the furnace

temperature of steam

effectiveness of electrical precipitator

and efficiency of the boiler etc.

have been analyzed

and the environmental problems that may be occurred due to implementing the said method being discussed. It is found that the availability ratio of the said desulfuration facilities to be basically identical with that of the boiler equipment.
