  • Method and apparatus for cooling exhaust gas in a kiln by-pass
    Patent number: 6017213
    Abstract: A probe having a double-tubed structure is provided to communicate with a kiln exhaust gas flowing path. A part of kiln exhaust gas is extracted through an inner tube of the probe, while cooling gas is supplied to a fluid flowing path formed between the inner tube and an outer tube of the probe. The cooling gas is guided to flow into an inner area of a front end portion of the inner tube so as to form a mixing and quick cooling area at a front end portion of the probe, thereby rapidly cooling the extracted gas.
