Job description

For the Thermal Technology department we are looking for interns! The following internships / graduation assignments are available. Apply using the apply button and select the (graduation) internship you are interested in.


Mechanical design optimization

Suitable for BSc or MSc in Mechanical Engineering

In the combustion plants of HoSt several components are designed and optimized. For some parts a detailed study with use of FEA is required. Analysis of the present mechanical design is an important part of this assignment. Focus is on lowering risk of damages and simplification of the design where possible.


Your tasks:

  • Familiarize yourself with all components of a Biomass Plant; 
  • Select a component/issue for optimization in consultation with HoSt engineers;
  • Study construction details of present design;
  • Analyse critical points and present improvements supported by FEA;
  • Present and document improved design.


Heat pumps at Biomass fired heat and powerplant

Suitable for BSc or MSc in Chemical Engineering / Mechanical Engineering / Sustainable Energy

HoSt is building biomass energy installations, but also explore own plants producing renewable gas, CO2, heat and power. At the HoSt biomass fired heat and powerplant in Andijk, HoSt is looking for the option to install a heat pump (or pumps). At this moment the flue gasses are already cooled very well (to 35 -40 C ) with the water coming from the green houses. The greenhouse can use more sustainable heat, therefor HoSt is looking to recover more heat from the flue gasses by cooling it to approx. 10 C. An other option is to use a part of the electricity of the wood fired CHP to supply electricity to a heat pump extracting energy from the air.


Your tasks:

  • Calculate how much heat is available in the flue gas at several temperatures;
  • Compare several integration options (parallel or in series with FGC);
  • Investigating the options of heat pumps: type of medium (CO2, Ammonia, propane), efficiency of the heat pumps;
  • One or to stage heat pumps heating based on return temperature;
  • Investigate the practical boundaries of implementing a heat pump;
  • Calculate the investment cost;
  • Calculate the economy of the options.

Heat pumps at Klazienaveen

Suitable for BSc or MSc in Chemical Engineering / Mechanical Engineering / Sustainable Energy

HoSt is building biomass energy installations, but also explore own plants producing renewable gas, CO2, heat and power. For the greenhouse project in Kalzienaveen, HoSt want to investigate the possibility to integrate heat pumps. We have several options to supply heat. The heat could be produced with a wood fired heat (and power) plants. An alternative is to use heat pumps and use the air or water from a channel to supply heat to a district heating system. The green house will use the heat at 45 up to maximal 50 C. A large influence will be the electricity price. So a model must be made where the heat pump is shut off during peak electricity prices and investigating the size of a heat storage. Also the availability of local gas engines in combination with tariff structure should be taken in to account.


Your tasks:

  • Calculate how large the heat pump should be in relation to the heat demand;
  • Investigating the options of heat pumps: type of medium (CO2, Ammonia, propane), efficiency of the heat pump , one or to stage heat pumps heating based on return temperature, investment costs;
  • Calculate the economy of the options.
