Abstract
Coal blends suitable for combustion in a slagging-type combustion apparatus comprise blends of (1) a bituminous coal which forms ash slag having unacceptably high viscosity with (2) a lignitic coal which forms ash slag having marginal viscosity characteristics or T.sub.cv whereupon combustion of the blends results in formation of ash slag having viscosity which is synergistically lowered and acceptable for slagging.
