The principle behind cogeneration is the simultaneous production of heat and power. Thanks to this combined heat and power generation, energy losses are reduced to a significant degree. Cogeneration thus makes it possible to save between 15 and 20% of primary energy, as compared with producing the same quantities of heat and power separately.
Let's take the example of a CHP unit powered by natural gas, yielding 35% electricity and 53% heat. The savings in primary energy amount to:
Savings = (1225-1000) / 1225 = 18%
Not only does the cogeneration technology make it possible to achieve substantial primary energy savings, but it also contributes to reducing the emissions of CO2 into the atmosphere.
CORETEC'S POSITION IN THE MARKET
As an engineering consultancy firm specialising in energy systems, CORETEC can undertake the planning, installation and supervision of a high-quality CHP unit and its auxiliary equipment.
CORETEC can therefore supply a complete system adapted to the customer's site.
The main stages in the service we offer are as follows:
- Study of suitability of potential projects identified
- Detailed feasibility study based on a series of on-site measurements
- Detailed study of draft scheme
- Compiling of specifications and selection of suppliers
- Purchasing of equipment and liaison with suppliers
- Installation and site supervision (civil, hydraulic, mechanical and electrical engineering, etc.)
- Acceptance of equipment and measurement of performance levels
- Guaranteeing of complete system, components and labour
- Management of grant and Green Certificate dossiers
Based on a contractual lump-sum investment, CORETEC guarantees the energy performance levels of the complete system.
"TYPICAL" PROJECTS
The type of project undertaken by CORETEC has the following main characteristics:
- High-quality CHP system allowing optimum recovery of the electrical energy and heat generated throughout the system's life
- Power capacity of between 100 kW and 5 MW
- Fossil fuel or biomass
- Energy and heat to be used within the Walloon Region
- Private or public customers
- With or without heating network connecting several consumers
Example:
In partnership with VMI, design, installation and supervision of a complete heating system powered by natural gas and comprising:
- A gas-burning cogeneration unit with a rated capacity of 1200 kW of electricity
- Two water boilers - 2 MW and 5MW
- Two oil boilers - 1.5 MW and 3MW
The heating appliances are automatically operated and controlled by a master control system.
