ABSTRACT:
This invention relates to continuous charging apparatus and in particular provides a gravity feed chute (8,9) for the particulate feedstock secured to the furnace roof (1) and which communicates with the internal furnace area. In order to prevent the furnace gases passing into the atmosphere through this chute a number of pipes (10,11) are provided which extend into the chute for injecting steam or other gases therein, so as to contain the furnace gases.
