摘要： The invention concerns a method of monitoring the operation of a system for feeding an abrasive medium using fluid as conveying medium for at least one burner in a fusion vaporizer plant. The dust extracted from a fusion vaporizer plant or reduction shaft furnace is to be introduced by means of a fluid and via a dust-conveyer tube through at least one dust burner into the fusion vaporizer plant as an additional carbon-carrier. However, the method can also be applied in other melting or incineration plants, such as for example fluid bed reactors. The object to be achieved by this method is to determine as rapidly as possible whether hot gases or unburned oxygen have/has flowed back into the dust-recycling system. To that end, the flow direction in the feed system conveying pipe is measured downstream of the burner or burners. When backflow of the fluid flow is determined or when the presence of oxygen which has penetrated the feed system is determined, the feed system is stopped.

摘要： In a process for returning finely dispersed solids discharged from a reactor vessel (1) with a carrier gas through a discharge point (2) of the reactor vessel (1) to a return point (15) of the reactor vessel (1), the solids are separated in a solid separator (4), in particular a cyclone separator, then returned with a carrier gas to the reactor vessel (1) while a differential pressure is maintained between the solid separator (4) and the return point (15). When the solids enter the reactor vessel (1), they are at least partially gasified and/or burned with oxygen supplied for that purpose. To enable the solids to be returned without moving parts which would be exposed to abrasion, in a continuous and controlled manner, the separated solids are directly and continuously aspirated by the solid separator (4) by means of a propellant gas and by an injector effect, accelerated and supplied to the reactor vessel (1).

摘要： The invention relates to a method of returning a finely-divided solid (4) extracted at an extraction point of a reactor vessel (1) from said vessel using a gas to a feed-back point (16) of said vessel. The solid (4) is separated in a solid separator (3), subsequently collected in a collector (8) and fed back from said collector to the reactor vessel (1) using a feed gas. To improve operation of the solid separator (3) without extra loading of the reactor vessel (1), an additional gas flow (23) which is independent of the gas flow in the reactor vessel is circulated through the solid separator (3) in the direction of flow of the solid (4).
