Performance Test Code - Coal Pulverizers
Establishes procedures for conducting performance tests to determine: 1.1.1 Capacity 1.1.2 Fineness of product 1.1.3 Raw coal feed 1.1.3.1 Grindability 1.1.3.2 Moisture 1.1.3.3 Sizing 1.1.4 Power Consumption 1.1.5 Effect of changes in raw coal characteristics on product fineness, pulverizer capacity, and power consumption. 1.1.6 Effect of changes in pulverizer component settings on product fineness, pulverizer capacity, and power consumption. 1.2 Scope. This Code applies to the pulverizing system as a whole, including all the component parts necessary to take the raw coal, hot air and tempering air at the system inlet, and deliver pulverized coal in proper mixture with air and/or flue gas at the desired temperature at the outlet of the system. This Code applies to the most commonly used systems. displacement compressors, uniformly accurate methods of tests are not available under all operating conditions. The Code specifically requires the parties to the te.
