Abstract

In a heat consuming physical or chemical process such as one in which air is supplied from a compressor (22) to a coal burning fluidised bed for example a catalyst regenerator (21) and waste gases pass to a hot-gas expander (24), supplemental energy required during start-up is supplied by a gas turbine, for example an aircraft gas turbine (28) which can be uncoupled from the process once the process has become self sustaining. <IMAGE>
