Subject of this project is construction of a new energy centre providing production of steam having required parameters for technological needs in SPOLANA, a.s.
In the new boiler house there are installed two steam boilers for steam production which burn natural gas. Power output of each boiler is 35 t / h of saturated steam at nominal steam pressure of 2.1 MPa (a).
Total steam power output of the boiler house is 70 t / h od saturated steam including own consumption of the boiler house. Structure of the boiler house facility is restricted to maximal heat input not exceeding 50 MWt.
Limiting condition of the proposed solution for the new boiler house is dealing with defined water level in the time of flooding . Based on the flooding level in the past the floor height of the new boiler house was defined as + 2 250 m.
