Two-dimensional pyrolysis studies were continued using Eastern bituminous coal. Unusual char formations (associated with the swelling nature of the material) have been observed, though tar and gas production per gram is not greatly different from that observed with Western subbituminous coals. Materials engineering support activities continued with work on properties of thick sections of steel, development of methods for nondestructive testing of coatings, cladding of low-alloy steels, fireside corrosion in fluidized bed boilers, failure analysis, and publication of a draft report on the use of prestressed concrete pressure vessels. Design and construction work continued in preparation for operation of the gas-fired boiler with potassium. Design studies of a coal-fired, alkali-metal-vapor, power system continued. Engineering studies and technical support continued with work on process modeling, the process research digest, a survey of industrial equipment capabilities, and a study of large air separation plants. Process and program analysis studies continued with work on low Btu gasification, direct combustion, advanced power systems, liquefaction, in-situ gasification, and beneficiation of coal. In the coal-fueled MIUS project, a 1000-hr endurance run of the coal feed system was completed and analysis of corrosion specimens exposed in a fluidized bed combustor was started.
