Technical Support for Operation and Maintenance

Operator cost savings due to increased reliability, safety, and lifetime

• Analyses of damaged parts in terms of properties of materials used;
• Evaluation and determination of root causes of defects;
• Recommendation, and proposal of system of measures and controls.

Unique technical and expert capabilities

• Accredited laboratories for standard and atypical material tests;
• Top experimental equipment and devices;
• Specialists in the fields of material engineering, thermomechanics, production technology, welding, voltage analysis and others;
• Production of experimental test specimens.

Elaboration of studies and documentation for the preparation and implementation of modernization of power plants. Studies and documentation for the next phase of the project can be processed for energy sources as a whole as well as for part of the operation.

Modernization of energy sources is usually done for the purpose of:

• Improvement of unit performance parameters;
• Improvement of the efficiency of electricity and heat generation;
• Optimization of operation and operating costs;
• Reduction of pollutant emissions and waste production;
• Improvement of unit operation comfort;
• Improvement of operational safety;
• Lifetime extension.

Project activities

• Feasibility studies;
• Project documentation DUŘ, DSŘ, IPPC;
• Basic Design documentation;
• Technical parts of Bidding Documents for supplier selection;
• Coordination documentation in the Detail Design phase and preparation of its selected parts;
• Author supervision.

Related engineering activities

• Identification and analysis of the actual state of equipment;
• Evaluation of the potential benefits of unit modernisation from the perspective of performance, efficiency, and operation;
• Evaluation of the technical parts of tenders;
• Technical support in negotiation with suppliers;   
• Coordination of the Detail Design.

ÚJV Řež can prepare studies and documentation for the preparation and implementation of energy generating plant greening projects. The studies may be prepared for energy generating sources as a whole as well as for partial operation sets.

The greening of energy generating units that burn solid fuels is intended to reduce the negative environmental impact of the units. This primarily includes the reduction of emissions into the air to make the levels of emissions compliant with Directive 2010/75/EU and with Act No. 201/2012 Coll., on Protection of the Air and Regulation No. 415/2012 Coll., on permissible level of pollution and its identification.

Another goal is to improve the efficiency of the entire generating unit, including the reduction of carbon dioxide (CO₂) emissions.

Possible solutions for the greening of sources:

• Change from solid fuel to liquid or gaseous fuel;
• Combustion modification, fuel conditioning;
• Reduction of solid emissions;
• Reduction of sulphur dioxide emissions;
  • Primary methods;
  • Secondary measures (wet, dry, and semi-dry methods);
• Reduction of nitrogen oxide emissions;
  • Primary measures (combustion modification);
  • Secondary measures (selective catalytic and non-catalytic reduction);
• Combined technologies to reduce emissions of SO₂ and NO_x.

 Preparation of documentation:

• Feasibility study;
• Basic Design documentation;
• Technical parts of Bidding Documents for supplier selection;
• Coordination documentation in the Detail Design phase;
• Author supervision;

 Related engineering activities:

• Identification and analysis of the actual state of equipment;
