摘要:
A steam system is disclosed having a steam boiler (14) designed to produce an adjustable supply of boiler steam and a steam accumulator (12) designed to supply all of the steam to steam load (66) as opposed to functioning as an auxiliary source to boiler (14). Steam accumulator (12) is a pressure vessel designed to function as a wet steam accumulator and sized to provide large quantities of steam in short bursts for a predetermined period of time to a sustained cyclic steam load (66) for a period of time sufficient to compensate for the time delays necessary to adjust the boiler steam produciton rate to equal changes in the average of the cyclic demand load. Accumulator (12) is formed of a pressurized vessel having a plurality of tubes (54) therein which are designed to have a sufficient heat transfer surface to transfer the majority of energy from boiler steam to the heated accumulator water (67) through conduction of heat through the tube heat transfer surfaces so that the majority of the boiler steam is actually condensed prior to being discharged into the heated accumulator water (67).

A power generating system includes a flow dividing structure, a first detector, a flow dividing adjusting valve, a heat accumulator, a heat exchanger and a turbine. The flow dividing structure divides a first heat medium into a first flow path and a second flow path. The first detector detects a flow rate of the first heat medium. The flow dividing adjusting valve opens the second flow path when the flow rate of the first heat medium exceeds a predetermined value. The heat accumulator accumulates the first heat medium via the second flow path and delivers the first heat medium at a temporally leveled flow rate. The heat exchanger transfers heat from the first heat medium to a second heat medium having a lower boiling point than the first heat medium. The turbine rotationally moves by the second heat medium with heat having been transferred by the heat exchanging unit.

A method and an apparatus recover heat and convert the heat into mechanical power in a drive system for motor vehicles. A working medium carried in a working medium circuit is evaporated by an evaporator integrated into the working medium circuit by waste heat from an internal combustion engine. The vapor generated is fed to an expansion machine coupled to the internal combustion engine, and the exhaust vapor from the expansion machine is then converted back into the liquid phase in at least one condenser. Accordingly at least one valve, which can be subjected to control by a control device, and a vapor accumulator are integrated into the working medium circuit downstream of the evaporator such that the vapor generated is fed into the vapor accumulator. The vapor stored in the vapor accumulator is fed back at least in part into the working medium circuit to drive the expansion machine.
