| 摘要 |
The invention relates to a process for local and small-scale production of electricity (13) by combustion of renewable fuel, and a plant (20) for carrying through the process. According to the invention the combustion takes place in a boiler (1), which for example has oil (2) as heat conducting medium. The heated oil (2) etc. conveyed from the boiler (1) is circulated through a heat exchanger (3) for heating water (4) in order to generate steam. The steam pressure (5) is conveyed to a number of membrane tanks (6, 7) or to a piston pump, where the steam is exchanged into water pressure (9) and is conveyed to a pressure tank accumulator (10). Said water pressure (9) drives a turbine (11), which in its turn operates a generator (12) to produce electricity (13). The return steam from the process is conveyed through a heat exchanger and/or a heat accumulator tank, where heat for the heating is produced. |
