Bio mass CHP plant, Vovchansk, Kharkiv region. Feasibility study
Site Location: Vovchansk, Kharkiv Region, Ukraine
Client: Department of Housing and Communal Services of Kharkiv Region State Administration
Design Stage: Feasibility Study
Summary of key solutions
The CHP plant is designed for use of straw and wood chips as fuel. The main building of the CHPP is designed as a two-bay variable-storey building, where the main and auxiliary equipment is located.
The CHPP main building consists of three sections:
- The Turbine Hall – the 18.0 m bay, the roofing beam elevation is 19 000 m;
- The Deaerator Hall – the 6.0 m bay;
- The Boiler Bunker Hall – the 34.0 m bay, the roofing beam elevation is 26,700 m along the axis B.
The CHPP Layout is "two boilers - the common steam header - the turbine". The location of the turbine generator set in the hall is longitudinal.
The Siemens turbine SST-111 is installed in the hall with an alternating current generator with the auxiliary equipment.
The design provides for installation of two boilers Е-20-6.5-490DR to be produced by "Kotloturboprom" LLC.
