Development of single stage toroidal flow coal fired MHD combustor
Studies and testing done at the Avco Everett Research Laboratory, Inc. (AERL) have considerably advanced the state-of-the-art of MHD coal-fired combustor design and operation. A prototype 20 MW MHD coal-fired combustor was designed, fabricated and tested. The slagging coal combustor design concept is a single-stage configuration which enables the achievement of high overall thermal efficiency. The vertical combustor has a downward flow, a cylindrical chamber, and a horizontal exit nozzle for directing the seeded plasma to a MHD generator channel. Combustion experiments at operating pressures up to 6 atm yielded the following data: combustion temperature of 2650-2800/sup 0/K, electrical gas conductivity of 6 to 7 mhos/meter, carbon utilization greater than 99.5%, and stable steady state operation.
