Brief Description of Main Solutions

The TETs (Heat & Power Plant) is intended for heat and electric power generation for process needs and heat supply to the gold deposit and ore-dressing & processing enterprise «Gross».

As the TETs main equipment are to be installed the five steam boiler units КЕ-25-40-440С of JSC «BiKZ» (Bisk town) manufacture and two back-pressure steam turbine generators ТГ8.0/6.3-Р3.4/0.25 of JSC «Kaluga Turbine Works» manufacture.

The heat power is to be used for:

• Process needs of the gold deposit and ore-dressing & processing enterprise «Gross», and in the 1st turn – for the leaching solutions heating;
• Heating and ventilation systems of the enterprise;
• Hot water supply system of the enterprise;
• Heating and ventilation systems, hot water supply system for the «Gross» shift-workers village.

This design documentation has obtained Positive Opinion of Federal Autonomy Management (FAU) of the Main State Expertise of Russia «Glavgosekspertiza of Russia».

The construction was started in 2016.
