METHOD FOR OPERATING SELF-BURNING CONTINOUS FURNACE AND CONTINUOUS FURNACE FOR CARRYING OUT THE METHOD

摘要

Method and device for operating a self-burning tunnel furnace with the aim of replacing high-grade energy carriers with unrefined ones, the burnable components contained in the charge material in this connection introducing the entire heat quantity required for the burning process, the calcining loss being minimised by its complete burning out and a selective control of the burning curve being made possible and the quality of the products being improved by porosisation. …This is achieved by: … …  - drawing off the smoke gas at a high temperature from the burning-off zone and mixing with cooling as well as fresh air and the injection, offset on both sides, into the preheater for the controllable heating and subsequent drying of the material …  - injection of combustion air at high speed variably over the entire burning-off zone as well as action with ballast air and selective smoke-gas extraction for controlling the temperature in the burning-off zone …  - closure of the preheater with a furnace door and a burning duct slide. … ……
