ASME Coal Sampling Test Procedure

ASME Coal Fineness Sampling Test Procedure Rev. 3/2010 Page 3 • Traverse points will need to be marked on the sampling probe based on an equal area test grid. Traverse points for a circular duct or pipe are calculated by first selecting the diagram below that corresponds to a 12" or larger pipe or a 10" – 11" pipe.

Combustion Testing and Research

Coal samples are initially homogenised by passing through a rotary sample divider. The homogenised coal is crushed with a Jacques crusher to -4mm before testing and milling in the pilot scale mill. The test mill is a Verticle Spindle Mill (Raymond Bowl type) with a 400 mm table diameter, 3 rollers and an integral double cone classifier. Crushed

Pulverized Coal Pipe Testing and Balancing

Collecting coal samples using an isokinetic probe provides the best data describing actual operating conditions inside the coal pipe. Source: Storm Technologies Inc. The isokinetic coal sampling method, although more difficult, is the best option for determining the true mill coal fineness produced and to calculate pulverizer performance.

Carbon Burnout Project – Coal Fineness Effects

The aim of DTI Project 226 "Carbon Burnout – Coal Fineness Effects" was to establish good quality plant and rig data to demonstrate the effect of changing coal fineness on carbon burnout in a controlled manner, which can then be used to support CFD and engineering models of the process. The project was designed to achieve this through:

ASTM D197-87 [9]. The quantity of coal passing each sieve is used to determine coal particle sizing. The fineness was determined by sieving through ASTM 50, 100 and 200 Meshes and plot into Rosin-Rammler distribution. The sampling activities and fineness test to investigate coal flow distribution are shown in Figure 1-3. Figure 1: PC pipes velocity

• After improving the fineness emphasis has. been given on flame failure and secondary air distribution in the furnace because burning is possible if coal particles are extremely fine and intimately mixed with the combustion air. In order to intimately mix the coal with air and for complete combustion 2% excess oxygen levels are needed. Most of the combustion …

Pulverizer Fineness

Higher fineness levels always promote more even distribution of fuel between a pulverizer's separate burner lines. Better distribution promotes better combustion, inherently lower NOx emissions and lower flyash L.O.I. or carbon content. The graph below illustrates actual test data on a pulverizer with varied fineness.

When the coal parameters were basically stable and vane opening was fixed, as the Mill output increased, the grinding force changed automatically at a similar rate the coal fineness varied, while slightly. The coal fineness R90 was basically within the range of 15-20%, suggesting that the grinding force was within the normal range.
