Method of and device for separating solid components from a hot combustible gas generated in a reactor

Claim 1

A method of separating solid components from a hot combustible gas which is under pressure and which is generated by partial combustion in a reactor of fuel which is an oil containing a fraction which forms ash upon oxidation of the oil, comprising the steps of generating the combustible gas in the reactor in a reaction region by partial oxidation of the fuel in an atmosphere of steam and oxygen at temperatures from 1000* to 1250*C, so that the components to be separated remain in solid condition, conveying hot combustion gas away from the reaction region, separating solid components from the hot gases in a separation region, cleaning the gas from said separation region by passing it through a rotation filter in an adjacent hot gas purifying system, and conveying the separated out solid components back again to the reaction region of the reactor for partial conversion to combustible gas in a further transformation of the combustible components.
