| 摘要 | A combined steam-high temperature water generating system includes a heated water generating vessel for delivering both steam and high temperature water to delivery circuits therefor. A portion of the heated water is continuously supplied to one or several forced circulation steam boilers which evaporate part, and only part of the throughput water flow. The return flow from the boiler or boilers to the vessel thus comprises a steam-high temperature water mixture. The system accommodates varying relative consumption demands for steam vis.-a-vis. high temperature water. Also, a chemical balance is maintained between the steam and heated water subsystem components by reason of the continuous water recirculation between the boiler or boilers and vessel. Further, the multifunctional use of the common heated water generating vessel renders the system amenable to ready fabrication. | ||||||
| 权利要求 | 1. In combination in a combined steam and high temperature water generating system, vessel means for including therein high temperature water and steam, steam boiler means, means for supplying heated water from said vessel means to said boiler means, said boiler means including means for evaporating only a part of the input heated water flow supplied thereto and for supplying as a boiler output flow a mixture of steam and high temperature water, conduit means for supplying said boiler output steam and high temperature water mixture to said vessel means, steam delivery means communicating with said vessel means for supplying steam therefrom, and high temperature water delivery means communicating with said vessel means for supplying water therefrom. 2. A combination as in claim 1 wherein said boiler means is of the forced circulation type, and further comprising pump means for urging water through said boiler means. 3. A combination as in claim 1 wherein said vessel means includes means for separating the steam-high temperature water mixture into its two constituents, high temperature water storage means, and steam storage means. 4. A combination as in claim 1, wherein said steam boiler means includes plural steam boilers. 5. A combination as in claim 3 further comprising water reaction surface means disposed within said vessel steam storage means, and means for supplying return water supplied by said water delivery means to said reaction surface means. 6. A combination as in claim 3 further comprising steam drying means disposed within said vessel steam storage means. 7. A combination as in claim 1 further comprising means for supplying make-up feedwater to said vessel means. 8. In combination in a combined steam and high temperature water generating system; vessel means including a steam-high temperature water input port, means for separating said steam and high temperature water, steam storage means, and water storage means, said vessel means thereby effecting high temperature water generation, and high temperature water subsystem expansion and pressurizing functions; steam boiler means including means for withdrawing high temperature water from said vessel means and for supplying said steam-high temperature water mixture to said vessel means. 9. A combination as in claim 8 further comprising steam delivery means communicating with said vessel means, and high temperature water delivery means communicating with said vessel means. |
