Brief Description of Main Solutions

   With the aim to enhance quality and reliability of the heat supply to consumers in Аk-Dovurak town, development of fuel-power complex of Tyva Republic is provided for the construction of water-heating boiler house of the installed heat capacity 50 Gcal/h (two boilers of 20 Gcal/h heat capacity each and one 10 Gcal/h heat capacity).

The water-heating boiler house has been designed for the rated heat power output to the heating networks of Аk-Dovurak town. The rated heat output as the hot water from the boiler house at the rated ambient air temperature of minus 48 °С for the heating system designing and at the temperature chart 95/70 °С is 30.333 Gcal/h at the existing heat supply system.

The heat power, generated by the boiler house, is used for:

• Heating systems for consumers of Аk-Dovurak town;
• Hot water supply systems for consumers of Аk-Dovurak town;
• The boiler house auxiliary needs heating and ventilation systems;
• The boiler house auxiliary needs hot water supply system.

This Project has obtained Positive Opinion of the State Autonomy Management (GAU) of the State Construction Expertise Management of Tyva Republic.

The construction was started in 2015.
