    Abstract

    Coal blending is an attractive solution for substitute coal as it is simple to apply, and considered to be cost effective. It is widely used either in coal mining to enhance its market acceptance or in coal power plants to meet the boiler fuel specification. The conventional coal blending system does not mostly consider the importance of size and distribution of the parent coals. The properties of blended coals will vary due to wide range of their parent coals’ size and their distribution leading to unexpected blended coals characteristics. A better homogenity of the blended cols characteristics is particularly needed for a better performance of pulverized boiler in a power plant. This paper describes our preliminary development on coal blending method for achieving better characteristics of the blended coals. A small scale continuous coal blending unit has been developed to investigate the validity of the blending method. Our preliminary results indicate a better homogenity of the blended coals when the parent coals are in uniform and smaller sizes prior to blending.
