Combined heat and power (CHP)


Combined heat and power

We offer advanced technologies with possibilities for reducing GHG emissions in the energy sector and to reduce the fossil resource dependency.

Maximise synergies available

VTT has 30 years' experience of applying combustion, gasification and pyrolysis processes to the needs of industry. By integrating these cutting edge solutions to your systems, you can maximize the synergies and flexibility.

Fast pyrolysis, gasification and advanced fossil power

Fast pyrolysis and gasification based conversions offer novel, efficient alternatives for increasing fuel and operational flexibility as well as process efficiency. Oxyfuel combustion enables lowering of CO2 emissions while still maintaining possibilities for utilising fossil alternatives in the fuel mix.

Tailored to your specific needs

We are a superior partner in developing fluidised bed processes with wide experience on different and challenging raw materials and vast experience on different applications. The experience and knowledge is based on world class experimental infrastructure and combining it with extensive modelling capabilities and understanding of processes.

​Waste to energy

New advanced technologies enable even more than 50 % higher waste-to-electricity efficiency and in addition to this, more profit can be earned by recovering valuable metals from residues of waste-to-energy (WtE) plants. Improved electricity production from waste results not only in better sustainability but also in better economy when more income is earned by higher yield of power for sale.


​​​Conversion of waste to energy

Gasification-based high efficiency  WtE technology enables almost 50% higher power production efficiency having a very positive impact on the economy of the plant, and at the same time fossil fuels can be reduced in power production.

​ ​​​

​​​Material recovery 

VTT has developed a patented advanced gasification process for the simultaneous recovery of energy and metallic aluminium from the waste stream of recycling of liquid packaging.


Combined heat and power

By implementing CHP+C (Combined heat and power + Cooling) concepts to energy systems in industry and municipalities one can gain benefits of over 90% production efficiencies and stable baseload demand for high profitability energy production without endangering process steam or heat supply. Superior system efficiency reduces environmental burden and increases profit.


​​​Supercritical CFB

Our strength is to combine experimental results obtained from Circulating Fluidized Bed (CFB) pilot- and bench-scale devices into modelling tools that have been developed so as to understand combustion phenomena in CFB combustion.

​​​Small-scale CHP

Our strength is in developing innovative solutions to utilize challenging biomass streams in energy production and combining technology experts, analytical, modelling and technical services and our wide research infrastructure.

​ ​​​

​​​Renewable and sustainable heating oil

We convert solid biomaterials to liquid biofuels using fast pyrolysis. Our competence builds on a thorough understanding of the liquid product, the process characteristics, and their role in scaling-up work.

 ​​​boiler operation

Boiler operation and lifespan

Advanced concepts for fuel characterisation, boiler design and boiler service and operation in both, pulverised coal (PC) and fluidised bed (FB) boilers are needed, to retain high operational hours and minimize unexpected downtime. With help of VTT you can minimise risks related to boiler investments and expansion of fuel mix.


​​​Fossil fuel replacement 

We develop and demonstrate sustainable high efficiency technologies for combined heat, cooling and power generation from biomass utilising pulverised fuel and fluidised bed combustion technologies, in both greenfield and retrofit plants. 

​ ​​​
​ ​​​ 

​​​Challenging fuel mixtures

VTT has gained an understanding of and developed methods to prevent ash deposition and high temperature corrosion during biomass and waste-derived fuel combustion.

​ ​​​
​ ​​​​ ​​​ ​​​​ ​​​

​​​CFD modelling 

We have over 30 years experience of the application and development of Computational Fluid Dynamics  (CFD) modelling tools for combustion and industrial multiphase flows. We have combined in an innovative way various modelling approaches with CFD.

​ ​​​

​​​Biomass supply chain

Our expertise encompasses applied research, feasibility studies and method development in the areas of harvesting, chipping and grinding, logistics, drying, handling, and upgrading of solid biomass fuels.

​Fresh thinking

Our customers tell us that collaborating with VTT adds value in a number of ways. It brings fresh thinking to the table, offers proven technologies that can be tailored to their specific needs, and accelerates the development and implementation process.

How we work

Working with VTT is different. Instead of developing everything internally or working with companies pushing proprietary solutions, we function as an extended part of your team. With VTT, you are tapping into Combined Heat and Power  (CHP)research and development that is both deep and broad.

Let’s talk

We invite you to meet with us so that we can gain a better understanding of the most important challenges you are facing and how we can help you to solve them.
