Conveying a material to be conveyed

A method for operating a conveyor system for continuously or discontinuously conveying a reactive and/or hot and/or abrasive material to be conveyed along a conveying path, the conveyor system including,

• a system housing which encases the conveying path, the system housing having at least one fluid inlet for directing fluid into the system housing, at least one fluid outlet for dispensing fluid from the system housing, a charging inlet for introducing material to be conveyed into the system housing, and a dispensing opening for dispensing material to be conveyed from the system housing;
• the system housing being embodied to be technically fluid-tight except for the at least one fluid inlet, the at least one fluid outlet, and the charging inlet;
• and
• the dispensing opening is the at least one fluid outlet or the at least one fluid inlet of the system housing, the method comprising:
• directing a fluid into the system housing through the at least one fluid inlet and in a fluid flow direction and transporting the material to be conveyed through the system housing in a conveying direction, wherein the fluid flow direction is substantially parallel to the conveying direction in which the material to be conveyed is transported through the system housing, 1 and directing the fluid to the at least one fluid outlet through the system housing.

• with the exception of the at least one fluid inlet and of the at least one fluid outlet, and of the charging inlet, embodying the housing so as to be technically fluid-tight, wherein the dispensing opening is a fluid outlet or is a fluid inlet of the system housing;
• directing a fluid into the system housing through the at least one fluid inlet, and in a fluid flow direction which is substantially parallel to a conveying direction;
• and transporting the material to be conveyed through the system housing directing the material to the at least one fluid outlet through the system housing;
• and
• forming a fluid atmosphere in the system housing which is closed-loop controlled in such a manner that the fluid atmosphere counteracts ingress into the system housing of a disturbance fluid from a neighboring apparatus which neighbors the system housing;
• closed-loop controlling of fluid pressure in the system housing to a nominal value which is higher than a current disturbance fluid pressure in the neighboring apparatus and recirculating fluid into a fluid recirculation system of the conveyor system housing and through the at least one fluid inlet;
• and
• trapping and reusing fluid exiting the system housing through at least one of the fluid outlets.
