Our contribution to the energy reversal!

Our revolutionary steam engine
for conversion of thermal to electric energy.


Our custom-made solution for environmentally friendly energy supply

In 2008 our technicians started developing a steam generating plant (which is heated with a grate burner) and a relaxing steam engine which provides green power to the net over a generator. In our innovative development we use RRM (renewable raw materials) for the steam generation with the use of optimized combustion technology. Our CHP-plant can be used in a modular construction system from 150 kW up to 1,5 MW thermal power and delivers from 30 up to 300 kW electrical power.

Description of the technology:
The system ("Green Steam & Neumot") consists of an external combustion unit, its waste heat is used for steam generation. This specially developed world protected natural circulation steam boilers (boilers with a defined water level, TÜV approved and certified) has a maximum water volume of 9.9 liters at a pressure ≤ 32 bar and meets the criteria of Class 1 boiler and boiler AUT class III D (low hazard potential).
By multistage overheating at 380 °C using a steam jet compressor is a given optimum steam quality at the steam engine subsequently installed. The steam expansion engine operates according to the displacement as a linear drive. The steam engine is fully enclosed, the power transmission is by means of a Crank drive completed.
The generation of electrical energy is done by an asynchronous generator. The 150 kW CHP generates up to 30 kW of electrical power and 110 kW (10 kW radiation and exhaust losses) thermal energy that (about 80 ° C) can be used for various inserts such as for Feeding into district heating systems, drying equipment or other heat consumers up to cooling plant operators can be used.

Advantages of our new conversion technology:
  • CO2-neutral combustion
  • Reduction of energy imports
  • Minimization of wood chips transport routes and utilization of local resources
  • Minimization of electricity and heat transmissions because of local use


The use of biomass for energy promotes the independence from fossil fuels and leads to a C O2-neutral combustion balance. Heating plants have the general disadvantage that it is very in summer is expensive, to a large boiler for a very small amount (base load) heat required to operate. By installing a small system the excess heat can be also used in the summer for the required base load. The power (green power) thereof is delivered throughout the year.

Another Advantages:
  • small plants possible ( > 150 kW)
  • fast payback period (5 years)
  • possibility of firing with various fuels

Possibilities for use:

Through the efficient and cost effective possibilities of central energy production in small power plants, the new technology „Neumot” can be used in many private, public and business locations. As it is operational from 150kW, commercial and agriculture businesses up to district heating plant providers could make use of this technology.

Example using horse manure
For all fuels with high water content (horse manure,chicken manure, wood chippings with 60% humidity …) we use our counterflow burner.
Suitable fuels
  • Fresh horse manure with max. 50% water content
  • Poultry manure
  • Wood chippings with 60% water content
  • Various mixtures of organic waste
    (max. 40% water content depending on the fuel)
Example for a 300 kW plant
  • Burning of horse manure with 45% water content
  • Fuel capacity, wet: 132kg/h
  • Anticipated electrical output per year:
    480MWh (based on 8.000 working hours per year)
