<p>1. Reactor apparatus for producing lean gas or generator gas from biomass or other low-temperature carbonisable waste products of all kinds, for example lubricating oils or the like, using a dual gasifier, comprising a primary gasifier with vertically adjustable level sieve and a discharging unit for the residues of combustion, the primary fuel and the pre-heated primary air being fed to the primary gasifier via the reactor bottom, and also comprising a downstream secondary gasifier in the style of a co-currently disposed coke generator with separate secondary air supply, characterised in that between the primary gasifier (2) and the secondary gasifier (20) there is provided a flue-current gas converter (14) into which passes a mixture of the secondary air for the secondary gasifier (20) and the low temperature carbonisable gas from the primary gasifier (2), along with the carbon particles exiting from the latter as a result of the centrifugal motion produced, the mixture and the carbon particles being channelled, with a high sojourn time under reducing conditions, by means of a radially symmetrical ring tuyere (19) to the secondary gasifier (20), and that in addition to the tuyeres (18) for supplying secondary air the flue-current gas converter (14) exhibits at least one foreign gas admission (30), said foreign gas admission (30) adapted to be connected, if required, to a bypass assembly to which at least a component current of the generator gas can be fed.</p> |
