Abstract
A wet-bottom, solid fuel gasifier has a slag tap through which a portion of the product gas is back-flowed through the slag tap to maintain the temperature of the slag hot enough to maintain continuous slagging. The reverse flow of the product gas portion is controlled by the negative pressure generated in the throat of the gasifier.
