This paper presents the pulverized coal dosing system and its working philosophy. Based on several researches on pulverized coal dosing system applied in the plant, two technical solutions are studied and compared, which are primary air utilized as pulverized coal loading air and compress air utilized as pulverized coal loading air. This paper studies the equipment adopted for each technical solution and their operation. Besides, the process flowsheet and design concept of pulverized coal dosing system for fuming furnace are introduced in this paper as well.
