Thermal power plants are comprised of the following main components which constitute the scope of Environmental Management Systems:
- Open-air yard for lignite storage (in lignite-fired plants)
- Lignite pre-crushing unit (in lignite-fired plants)
- Evaporation boilers with steam turbine and corresponding generator
- Condenser receiving steam from the steam turbine
- Cooling tower
- All necessary electro-mechanical equipment and circuits of water-steam, combustion air and flue gases
- Lubricating systems
- Step-up Transformers
- Connecting facilities between transformers and the sub-station where transmission lines start from
- Plant control and operation Systems
- Chimneys
- Collection and disposal systems for flying ash and wet ash (in lignite-fired plants);
- Ash transportation systems (conveyor belts) to the depot (in lignite-fired plants
- Water demineralization and softening units and condensate refining system
- Water storage tanks (demineralized, polished, drinking water)
- Oil tanks and all the necessary equipment for transporting oil to boilers
- Wastewater Treatment Complex, collection network and treatment facilities
- Industrial Wastewater Treatment Complex that receives all liquid waste from the Plant (networks, treatment facilities);
- Various auxiliary facilities such as: Machine Shop, Electrical Workshop, staff servicing facilities, etc.
- Active fire-protection system.
The Environmental Management Systems in Thermal Power Plants apply procedures for:
- Management of solid waste, hazardous materials and waste, used water and effluents
- Control of air emissions and monitoring of greenhouse gases
- Planning and carrying out maintenance work, handling failures and upgrading/modernizing Units and Anti-Pollution Equipment
- Periodic checks of other equipment to avoid accidents and risky situations for the environment
- Noise control
- Prevention of and response to contingencies.
