Steam Storage Reservoirs
Steam storage reservoirs are designed as horizontal pressure vessels with cylindrical sheating, enclosed by dished heads. A heating steam distribution system inside the storage reservoir provides the heating of its water contents. Internal steam distribution depends on the flow and parameters of inlet charging steam. The storage reservoir is supplied on bearing supports, sheeted and insulated. To assure a clean steam outlet, a built-in structure, placed before the steam outlet, arrests the water carried by steam.
Storage reservoirs are available in capacities from 4m3 to 40m3.
Maximum design pressure: up to 2 MPa
Maximum charging steam temperature: up to 300 °C
Hot Water Storage Reservoirs
They are available in two modifications:
- Pressurised storage vessels
Pressurised storage reservoirs are vertical, insulated vessels of cylindrical shape. There is a built-in structure inside the vessels, limiting heat losses during charging and discharging. The built-in structure is always designed for a particular pre-set charging and discharging capacity of the storage reservoir, maintaining its maximum heat storing capacity.
Technical parameters
| Maximum allowable temperature drop – cold/hot water: |
25 °C |
| Maximum water temperature: | 200 °C |
| Maximum design pressure: | 1,4 MPa |
| Vessel capacity: | up to 40 m3 |
- Pressure-free storage reservoirs
Pressure-free storage reservoirs’ vessels are designed in the form of standing cylindrical vessels, manufactured, equipped, checked, tested and approved according to ON 69 8119. The built-in structure inside the vessel prevents water from mixing during the charging and discharging operations.This structure is always designed for a particular pre-set charging and discharging capacity, maintaining the storage reservoir’s maximum heat storing capacity. The inside surface of the vessels has an anticorrosive protection system. This system extends the durability of the vessels without the necessity of having to increase the vessel weight by anti-corrosive surfacing.
Technical parameters
| Maximum allowable temperature drop – cold/hot water: |
25 °C |
| Maximum water temperature: | 95 °C |
| Vessel capacity: | up to about 25 000 m3 |
