[Study on feasible emission control level of air pollutions for cement industry ]
Abstract:
The revised National Emission Standard of Air Pollutions for Cement Industry has been issued, which will be effective for the new enterprises and the existing enterprises on Mar. 1st, 2014 and July 1st, 2015, respectively. In the process of revision, the key technical issues on determination of standard limits was how to determine the feasible emission control level of air pollutions. Feasible emission control requirements were put forward, according to air pollutants emission, technologies, environmental management requirements and foreign standards, etc. The main contents of the revised standard include expanding the scope of application, increasing the pollutants, improving the particulate and NO emissions control level, and increasing special emission limits applied to key areas of air pollutants. The standard will become the gripper of pollution prevention, total emission reduction, structural adjustment and optimization of the layout, and will promote scientific and technical progression for the cement industry.

Types of Cement I
Type I (Ordinary Portland Cement) is widely used for general construction where special properties are not required. It has moderate sulfate resistance and heat of hydration.
Type II (Modified Cement) offers moderate resistance to sulfate attack and a lower rate of heat development compared to Type I. It is suitable for structures in...
