<p>A closed container partially filled with liquid with exhaust gas inlet and outlet devices. Internal structure provides a path for the gases, particularly furnace exhaust gases, between inlet and outlet devices and, while passing along the path, the gases are passed through the liquid which absorbs heat from and removes constituents from the gases. One embodiment passes the gases physically through the body of liquid whereas in an alternate, gases pass over the liquid body and are subjected to a spray which causes heat transfer and removes exhaust constitutents from the gases. Various devices can be used to agitate the liquid, automatic controls and operators can be used to maintain desired liquid level, and outlets, which can include automatic controls, are provided to remove collected sludges or constituents. Heat exchangers using conduction, radiation and convection principles of heat transfer can be added to utilize recovered heat energy.</p> |
