Hydraulic driven units
Robust hydraulic solutions for biomass transport, compaction, and automation.
Combined Heat and Power (CHP) Plants
Biomass CHP technology delivers high-efficiency power and heat from renewable, locally sourced fuels.
CHP
Combined Heat and Power (CHP) is a way to produce electricity and heat at the same time in one process. It uses one fuel source to generate both forms of energy, making the system more efficient compared to separate production.
Biomass as a Renewable Energy Source
Biomass has become one of the most common sources of renewable energy. Due to its low cost and wide availability, it is extensively used, especially in Combined Heat and Power (CHP) plants.
What is Combined Heat and Power (CHP)?
Combined Heat and Power (CHP) refers to the simultaneous production of electricity and heat within a single thermodynamic cycle. This process can utilize solid biomass, gas, or liquid fuels as input.
Biomass in CHP Plants
In biomass CHP plants, biomass serves as the primary fuel source. Often, it is sourced directly from byproducts of existing production processes, making it a highly efficient and sustainable energy solution.
Applications of CHP
CHP systems are used across various sectors, including:
- District heating plants
- Wood processing plants
- Agricultural product processing facilities
- Waste processing plants
These facilities not only require both heat and electricity but often have biomass readily available as a byproduct of their own operations.
