Abstract
In thermal regeneration incineration apparatus having a main combustion chamber in communication with at least one heat-exchange section to which inlet and outlet ducts are connected, each duct having an associated valve, purified effluent from the output of the apparatus is fed back to blanket at least one side of one or both of the valves. This helps to prevent unpurified effluent applied to the input of the apparatus from leaking through the valves when nominally closed and thereby avoiding passage through the main combustion chamber.
