Knowledge of moisture content in raw coal feed to a power plant coal mill is of importance for efficient operation of the mill. The moisture is commonly measured approximately once a day using offline chemical analysis methods; however, it would be advantageous for the dynamic operation of the plant if an on-line estimate were available.
Types of Boiler Coal Pulverizers
There are basically three different types of pulverizing. 1. Attrition Type. Coal feeds onto a steel rotating table. Tapered, cylindrical, or spherical rollers on top of the table, under spring pressure, exert force on the coal particles on the table. When the table rotates, the coal passes between the rollers and the table and gets ground due ...
Mongolia and coal
In 1990 Mongolia exported a little under half a million tonnes of coal and buoyant domestic demand consumed a further 6.6 million tonnes. But the coal mining sector in Mongolia experienced a dramatic slump following the political and economic upheavals in the former USSR, which withdrew financial and technical support.
