Coal technology program progress report for February 1977

Description: 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… more
