Summary

The objective of the program is the continuation of essential experimental work aimed toward the demonstration of long duration MHD generator operation with the extraction of practical power levels from open cycle MHD generators. The present program will ultimately lead to the delivery, installation and test of generators of 40 to 50 MWt capacity at the CDIF in Butte, Montana. Progress during the three month period for each of the five program tasks is presented. Preliminary performance and lofting calculations are presented for the first CDIF power channel to be operated in a 3 teslas iron core magnet in conjunction with the PERC combustor. These calculations help formulate magnet and combustor operation specifications together with cooling and instrumentation requirements for the channel. The Electrode Test Section has been completed and been subjected to three tests, with a cumulative duration of 9.2 hours. Experiments were performed in order to assess the effectiveness of current controls for a generator with external diagonal connections. The most recent experiments on the disk generator utilize radial flow and a working fluid that is a very close simulation of the combustion products of coal burned with preheated air. Nominal channel mass flows are 30 kg/sec at a corresponding enthalpy flow of 120 MWth. Experiments yielded a peak output power of 3 megawatts for an applied magnetic field of 2 tesla. Modification of the high temperature regenerative air preheater facility and assembly of the coal combustion research test rig was completed. Studies on the behavior of coal particles when injected into hot vitiated air were continued. (WHK)
