Abstract
A unique valve mechanism for opening and closing inlet, outlet, and purge valves in a regenerative incinerator is disclosed. The valves are mechanically opened and closed by a cam arrangement which insures proper timing, and optimal volume flow through the valves during each cycle. Further, a method of the present invention begins the purge mode while the inlet valve is opened, and completes it after the outlet valve has opened. This reducing the required time for each cycle of operation.
Claims15
A regenerative incinerator comprising:
- a combustion chamber;
- a plurality of heat exchange chambers leading into said combustion chamber, said heat exchange chambers each having a line leading to a source of air to be cleaned, a line leading to a downstream destination for clean air, and a purge line, said inlet line delivering air to be cleaned through said heat exchange chamber and into said combustion chamber in an inlet mode of operation during each cycle of operation, said outlet line receiving air from said heat exchange chamber after the air has been cleaned by combustion within said combustion chamber in an outlet mode of operation, and said purge line replacing air within said heat exchange chamber between said inlet and outlet modes;
- and
- a valve disposed on each of said inlet line, said purge line and said outlet line, said valves being mechanically actuated to open and close.
1 more element
A method of operating a regenerative incinerator with a plurality of heat exchange chambers comprising the steps of:
- (1) directing air to be cleaned through a heat exchange chamber into a combustion chamber by opening an inlet valve;
- (2) incinerating the air within a combustion chamber;
- (3) closing the inlet valve;
- (4) directing cleaned incinerated air through the heat exchange chamber by opening an outlet valve;
- and
- (5) opening a purge valve to replace air in the heat exchange chamber prior to beginning step (4), the purge valve being opened prior to step (3), but after step (1).
