In the production process of NSP cements, consumption of powered coal is mainly consumed in two equipment: rotary kiln for clinker calcining and decomposing furnace for calcium carbonate. In order to know the fuel utilization in the rotary kiln and decomposing furnace. The main method to monitor fuel combustion is to monitor gas components.
