Abstract
A method of online control of a slag-forming process of gasification of a carbonaceous solid fuel, especially coal, in a gasification reactor with supply of a gasifying agent and a moderator is provided. Certain embodiments relate to a gasification process for producing a product gas including carbon monoxide and hydrogen from a solid fuel, to a computer program for online control of the slag-forming gasification process, and to a plant for conducting a gasification process for producing a product gas including carbon monoxide and hydrogen from a solid fuel. Certain aspects of the invention combine an online solid fuel analysis with a process model in order to operate a gasification process for solid fuels by the feed-forward principle at the thermodynamically optimal operating point. The invention permits the establishment of the operating point in real time in order to react to rapid variations in the composition of the solid fuel. Certain embodiments also permit the complete automation of the gasification process.
