Biomass power plants – CHP (Combined heat and power) technology

Our biomass power plants (cogeneration plants) are produced for the energy supply of industrial processes and can be operated with steam or silicone oils. In a cogeneration process heat and electricity is generated. For the electricity production are used high mainly quality steam turbines. The modular design of our systems allows the detailed implementation of the plants according to the customers requirements and the respective fuels. The power plants are built up turnkey and handed over ready to work to our customers.

CHP plants – industrial applications up to 7.000 kWel

• steam parameters of up to 35 bar and 500 °C
• generate clean electricity and heat from biomass
• possible producing up to 7.000 kWel and 28.000 kWth ( depending on the system design and fuel specification)

 

The heavy industrial design is distinguished mainly by their durability and robustness. Flexible heat output parameters make these reliable systems interesting to a wide range of applications.

CHP Compact plants – work ready power plants up to 500 kWel

 

The compact systems CHP were developed specially for export projects and decentralized power applications. This plant type from 200 to 500 kWel is characterized by a very compact and space-saving design. All internal piping and electrical connections are prepared at the factory, so that the equipment can be delivered ready for use. The compact units are prefabricated at the factory on corresponding steel frames for quickly installation and start-up on side.

application areas for the CHP system:

• Wood industry
• Pellet plants
• Drying plants
• District heating nets
• Dairy industry
• Brewery industry
• Green houses
• Food production industry

Plant design – customer specific and individual

 

The electrical power production is directly coupled to the heat consumption. 100 % output of the heat generator produce approximately 18 % electrical and 82 % thermal energy, depending on the operating parameters. In this division heat is available at a temperature of 90 °C. The lower the heat output temperature, the more electrical power and less heat power can be produced.

 

Waste heat usage – flexible process parameters and applications

 

The process heat occurred from the cogeneration process can be made available in the form of process water or process steam in a temperature range from 40 °C to 200 °C and a power range of 1.000 to 28.000 kWth. For the electrical power production back presure-, condensation-, or extraction turbines are used to provide the required process parameters. For a regulated power plant operation a continuous heat consumption is very important. In addition, variation of the heat consumption can be compensated with fully automatic cooling systems.

Drying with biomass – HotAir-Technology

Our hot air generator systems are manufactured for the energy supply of industrial and agricultural drying plants. With the use of regionally available biomass instead of fossil fuels, the drying costs can be significantly reduced. Flexible technology and years of experience in the design of hot-air systems allow the combination with almost all available dryer models.

HotAir Generators –  industrial technology for high performance up to 10.000 kWth

Hot Air Generators  are made with a thermal capacity up to 10.000 kWth and can provide hot air volumes up to 400.000 m³/h and temperatures up to 1000 °C for all drying applications. The robust design allows the use of a wide range of different biomass fuels.

Flexible technology – many applications

 Our hot air plants are working with different drying system across Europe. The systems are always specified to the requirements of the drying plant. The flexible design allows to combine almost any drying system with our biomass technology:

• Tower dryers
• Belt dryers
• Feed and turn dryers
• Drum dryers
• Flat grate dryers
• Fluidized bed dryers
• Drying chambers

Gently product drying – indirect hot air generators up to 200 °C

 Our indirect hot air systems are used everywhere, where clean fresh air is needed. Especially in the food industry, the indirect drying becomes more popular, since the drying product does not come into contact with the exhaust gases from the combustion process. Through the use of an efficient and specifically for biomass designed exhaust gas / air heat exchanger, clean hot air can be produced up to 200 °C. So also modern drying systems with heat recovery installations can be powered optimally with our technology.

High-temperature drying – direct hot air generators up to 1.000 °C

For drying of mineral products such as sand or stones, high drying temperatures are required. With our biomass fired, direct hot air systems can be provided, depending on fuel humidity, hot gas up to 1000 °C. The combustion gas from the biomass combustion is mixed in a mixing chamber with cold air and the required drying temperature is automatically regulated. About optional hot gas fans also overpressure drying systems (such as fluidized bed dryers) can be combined with our systems.

The patented Toploader system is the most economical storage technology for various bulk materials like wood chips, old timber, bark, RDF, corn, grass, pellets and plastics. Applications are for example boiler feeding in biomass power plants, receiving stations for larger storage units in the fuel area, storage boxes for wood chips and shavings in pellet plants, substrate storage and feeding of biogas plants.

The Toploader system provides for fully automatic box evacuation without operating personnel. One or more boxes with each up to 400 m³ content get filled from the open side on plane ground area by semi-trailer, tipping scrap skips or wheel loader. The removal is effected with the Toploader on the opposite over a sloping ramp to the subsequent conveying technology with a conveying capacity of up to 100 m³/h. There is a paddle suspended on one side of a movable slide by guide bars that is continuously moved to and fro. During the return movement the paddle is raised and gets re-placed on the floor in front of the material – a new cycle begins. What`s worth to point in this system – there is no pit at the unloading side required. Combined with a simple concrete bottom plate, pre-casted concrete blocks, asphalt surfaces or metal plates there are versatile, cost-effective design. Drive, lifting device and mechanical devices are always outside of the bulk material, accessible at any time and easy to maintain.
