ABSTRACT:
Disclosed is a method, a system and an improved butterfly valve usable therein for recovering energy from a continuous supply of hot pressurized particulate-laden flue gas. This gas is conducted to the atmosphere via a selected one of a plurality of ducts equipped with separate purgable butterfly cut-off valves each located upstream both from the point of gas disposal to the atmosphere and from separate energy recovery devices. Each duct has provision downstream from an associated cut-off valve for insertion of a slip blind crosswise of that duct after closure of the cut-off valve thereby permitting servicing operations on the energy recovery device deactivated by the closed valve or valves. One or more of the recovery devices is usable to supply operating power for components of the system or to other equipment.
