Show particulate control. The facility is also equipped with extensive instrumentation and a computer-controlled data acquisition system. A detailed description of the test facility 4 5 is given in previous publications. ' A systematic COM combustion test program was initiated in the Fall of 1978 and completed in the Spring of 1981. The program included the following: 1. Baseline tests with No. 6 fuel oil ' 2.* Tests with COM containing 30, 40, and 50 percent coal pulverized to a particle size consist of 90 percent minus 200 mesh ' 3.* A 500-hour duration test with COM containing 40 percent coal 4.* COM tests with three different coal particle size consists (92 percent minus 325 mesh, and 86 percent and 60 percent minus 200 mesh) in 40 percent COM6 5. COM tests with three different coal types (Pittsburgh seam coal, Montana subbituminous coal, and Illinois No. 6 coal) 6. Tests to evaluate the effectiveness of soot blowers in removing ash from the radiant section of the 700-hp boiler Results of COM Combustion Tests When firing COM fuels in the 700-hp boiler, COM was introduced into the boiler through a single package burner manufactured by Coen Company.** The internal mix, steam-atomized burner was designed to fire No. 6 fuel oil supplied at a pressure of 150 psig and a viscosity of 100 SSU to 150 SSU for good atomization.
