Pulverized Coal Pipe Testing and Balancing By Richard F. (Dick) Storm, PE The first step in optimizing combustion system performance is balancing the air and fuel flowing through each of the plant's coal pipes—the pipes that convey the air/fuel mix from the pulverizers .
Steam power plant configuration, design, and control Xiao Wu,1 Jiong Shen,1 Yiguo Li1 and Kwang Y. Lee2∗ This article provides an overview of fossil-fuel power plant (FFPP) configura-tion, design and especially, the control technology, both the conventional and the advanced technologies. First, a brief introduction of FFPP fundamentals and con-
pulverized coal can be introduced directly into the boiler for combustion. There are several pieces of equipment involved in processing coal to be burned in this fashion. Figure 1 is a simplified diagram detailing this equipment in a direct-fired coal burning system. Combustion Engineering, Babcock & Wilcox, and Riley Stoker Corp. are major
The material to be pulverized is introduced into the center or side of the pulverizer (depending on the design). As the lower ring rotates, the balls to orbit between the upper and lower rings, and balls roll over the bed of coal on the lower ring. The pulverized material is carried out of the mill by the flow of air moving through it.
