An experimental unit was built to burn 125 lb of coal per hour at 4,000 deg f in a cyclone burner with oxygen-enriched air preheated to 1,500 deg f to ascertain the fireside corrosion problems that might be encountered in the coal-fired mhd generation of power. Haynes 25 was slightly attacked at 1,500 deg f wall temperature, the stainless steels 310, 316, and 446 were resistant at 1,100 deg f, and carbon steel was attacked at 800 deg f.
