Effects of calcium magnesium acetate on the combustion of coal-water slurries. Thirteenth Quarterly project status report, 1 September 1992--30 November 1992
Production of CWF agglomerates of pulverized coal grind has commenced. A bituminous coal PSOC 1451 HVA coal has been obtained from the Penn State Coal Sample Bank, size classified in the 38-45{mu}m range. This coal was mixed with water (40 % solids) and with 1% ammonium lignosulfonate as a dispersant. Generation of pre-dried CWF agglomerates has been conducted in a thermal reactor, as described at an earlier report. The solenoid actuator-driven single drop generator is used fitted with different size needle-plunger combinations. During the present, 14th quarter, the following tasks are being conducted: (a) Measure the gas temperature profiles in the new furnace and recalibrate the pyrometer. (b) Generate an inventory of CWF agglomerates of different coal grinds and carbon black with and without CMA. (c) Conduct high temperature experiments to identify differences in the combustion behavior of agglomerates of different coal grinds, and (d) efforts will be conducted to capture the resulting ash particles for visual observations.
