ABSTRACT:
An apparatus and method for controlling exhaust produced by a reactive chamber is provided. The apparatus for controlling exhaust may include, for example, a valve body having an exhaust hole for the exhaust to pass through, and may include a first and second valve which regulate the opening and/or the closing of the exhaust hole. A control device may control the operation of the first and second valves based on the internal pressure of the reactive chamber.
