2019-5-6 · Dry Feed vs Slurry Feed Coal is typically fed into a pressurized gasifier either pneumatically as a dry solid or pumped as coal-water slurry. Slurry-fed feed systems have a lower capital cost, but result in less efficient conversion of coal to syngas (referred to as the "cold gas efficiency" of the gasifier).
