ABSTRACT:
Regenerative compression-combustion-expansion cycle engines are utilized to generate hot, high pressure gases for heat transfer use. The gas generation equipment includes temperature modulation by water injection, recycle of spent gas, and injection of turbine-expanded gas into the main hot gas stream. Separate combustion chambers are also utilized for exploiting low-cost fuel and increasing gas temperature. Special heat transfer equipment including helical nozzle arrays are provided for paper drying, the nozzle arrays being arranged to indirectly heat materials, such as paper, being dried, to radiantly heat such material, and to directly heat such material by impinging hot gas directly thereon. Continuously cleaned rotary filters, as well as jet operated doctor blades may be used in association with the nozzles. Hot high pressure gases are also employed for water removal from paper and similar materials by being forced through wet paper carried between two felts, and equipment leading the gas to and away from such a felt-paper sandwich is provided. One embodiment of such equipment includes an impervious gas conducting belt. The use of hot high pressure gases as a source of flow and turbulent energy for heat transfer purposes results in extremely efficient heat utilization, and the heat transfer equipment exploits to the fullest the properties of such hot pressure gases to minimize film resistance to heat transfer.
