This project is mainly aiming at checking and counseling continuous emission monitoring system (CEMS) from the first announcement. The project targets are to improve the checking and management abilities toward the CEMS of the environmental protection organizations, to assist Environmental Protection Bureaus to establish and to use CEMS online software, and to promote CEMS management and technique. The first group on-line stacks include boiler generating procedure, cement manufacturing procedure and arc furnace steel-making procedure. In total, there are 192 sets of stacks of 72 factories. All of them are already on-line. The second group of on-line stacks is of waste incinerating procedure, which includes 62 sets of on-line stacks of 25 factories. The third group of on-line stacks is of boiler generating procedure(80~130 ton per hour), chemical manufacturing procedure and coking and burning procedure of iron ore primary melting. In total, there are 55 sets of stacks of 21 factories. The rate of on-line is 36%.CEMS checks 20 sets of stacks of 19 factories, and the results are as below. Monitoring results are not corrected properly. (ie. Not being able to correct moisture content and revise oxygen content), therefore effects the monitoring data. Consequently, the declaration of the air pollution fee is only up to 50%. The rate of disqualification on Opacity adjustment inaccuracy checking is 15.8%, the rate of disqualification on standard air checking is 20%, and the rate of disqualification on zero / span drift checking is 5%. Moreover, the rate of refusal for signal output matching is 25%, and most of them is under a miner drift condition. The result was provided as air pollution fee verification reference. Along with our counselling, the public and private places are requested to improve and correct the defect as to meet the law demand.
