6 FAQs about [Paramaribo steam storage tank]
What is a steam accumulator storage tank?
The storage tank of a steam accumulator must be able to withstand the pressure of the water, including hydrostatic pressure. The storage tank accounts for the larg-est portion of the capital cost of a steam storage tank. One focus of the design is to minimize the mass of the storage tank for safe operation.
What is a dry steam storage tank?
According to [Goldstern1963], dry steam storage tanks with volumes up to 3000 m 3 have been built for maximum steam pressures of 1.2 bar. To avoid the pressure drop during discharge, the bell accumulator with variable storage volume was developed. Similar to a gasometer used to store low-pressure natural gas, the bell floats on a water reservoir.
How much steam can be stored in a dry storage tank?
For low steam pressures, there is the possibility of direct storage of superheated steam, but the low storage density of steam requires large volumes. According to [Goldstern1963], dry steam storage tanks with volumes up to 3000 m 3 have been built for maximum steam pressures of 1.2 bar.
What is the storage capacity of a sliding pressure steam accumulator?
Volume specific thermal storage capacity of a sliding pressure steam accumulator operated at starting pressures between 2 and 10 bar for a specific reference enthalpy of 0 kJ/kg at 0 °C; arrows indicate the storage capacity for an exemplary discharge from 10 bar to 3.5 bar
How much water is needed for steam storage?
Boiler: Maximum continuous rating = 5 000 kg/h Normal working pressure = 10 bar g Accumulator: Mass of water required for steam storage = 65 920 kg (fully charged and 90% of vessel volume) P1 (boiler pressure) = 10 bar g (fully charged) P2 (discharge pressure) = 6 bar g (fully discharged) Plant requirements:
Can prestressed cast iron tanks be used for steam storage?
The use of prestressed cast iron tanks was proposed in [Gilli1977] as an alternative to welded steel tanks in large-scale steam storage for power plant applications. The use of underground caverns for the storage of pressurized liquid water was presented in a feasibility study [Dooley1977].
