Following the successful review of our feasibility study, Schmid Energy chose Bluebox Energy to provide a DUO+ hot air turbine system to accompany their biomass furnace. The system wil generate 100kW of electricity as well as provide heat to a site in Dudingen.

Schmid energy solutions is a Swiss family business, which has been dealing with energy issues for over 75 years and employs around 300 people. Schmid have evolved into a specialist manufacturer of biomass energy systems.

Due to their complexity and maintenance requirements, Schmid Energy have found that ORC systems and steam turbines only become worthwhile as large-scale systems with a thermal capacity above 2 MW. In many cases, heat offtake all year round cannot be ensured for such high capacities. The hot air turbine therefore fills the gap in the smaller operating range.

Schmid Energy have developed a prototype hot air system with a micro-turbine system.  However, they wished to find an alternaive with improved performance and asked BlueBox Energy to perform a study to evaluate the performance and economics of our hot air turbine solution coupled with Schmid Energy’s combustion and heat exchanger system.

Due to the need for high efficiency’s, the study concluded that the Duo+ system was the most suitable.  Schmid Energy are now in the process of deciding whether to move forward with the technology.

We assisted Bowman Power in their development of a turbogenerator system for a Caterpillar 3516 engine in Sumatra.

Testing was held at site over a period of one week and confirmed the performance of the engine system was as anticipated and gave the team valuable information on how the engine performed in this environment.
