From biomass to electricity

icon-new4

Turn your biomass waste into electricity and heat with TEOPOWER, an innovative solution developed together with our partner SuperBrix in Colombia. TEOPOWER can be applied to rice husk, sawdust, olive pits, bagasse, coffee pulp, soya bean residue and more.

The Challenge

icon-new2

Today, the competitiveness of a rice mill is not only affected by the cost of the energy it uses but equally the cost of managing its biomass waste. To help with this challenge, SuperBrix has promoted the use of rice husk (the outer layer of the grain which is removed during the milling process) for drying the rice by developing and using its TEO biomass furnaces for more than 30 years. However, mills still have excess rise husk, which is a costly operational burden.

The Solution

icon-new3

TEOPOWER minimizes the volume of rice husk waste by burning and transforming it into electricity and heat. The results are achieved through the integration of two proven technologies: SuperBrix’s TEO biomass furnace and Viking Heat Engines’ CraftEngine.

Operational benefits:

  • continuous base load power production: no storage required
  • high flexibility: adapting to demand between 10-100 per cent of capacity
  • wide range through modular solutions: 
10-500kW of power
  • low-cost, highly reliable and low-maintenance

Commercial benefits:

  • increases competitiveness by reducing operational cost
  • ensures compliance with environmental regulations
  • increases energy efficiency and is environmentally friendly
  • supports brand positioning and social responsibility
  • provides potential for legal and fiscal incentives

Q&A

What is TEOPOWER?

TEOPOWER is a so called combined heat and power (CHP) solution. It's a biomass boiler/burner that produces electricity and heat e.g. for drying.

TEOPOWER is the combination of two proven technologies: The CraftEngine and the TEO furnace.

The TEO furnace is an innovative cyclonic burner that burns rice husk, or other biomass waste such as wood waste and corn cob, and produces heat for drying. SuperBrix has developed this system continuously over the last few decades and the TEO furnace is a proven technology in the industry.

The CraftEngine uses heat to produce power. The innovative organic ranking cycle (ORC) engine has been specifically developed to use heat on a small scale and produce on-demand power from it. Due to its piston-based technology, which was very much developed like a car engine, it's unique in its flexibility towards power demand, easy to operate and requires little maintenance.

How does it work?

Heat is produced by the TEO furnace, using rice husk or other biomass waste. Part of that heat is transferred to the CraftEngine for power production, using a heat exchanger. The remaining heat is used in the process of drying, for example when drying rice to enable the milling process.

The innovation is the use of an off-the-shelve heat exchanger to connect the CraftEngine to the already existing heat source, which is SuperBrix's TEO furnace.

Can it only be used with rice husk waste?

Not at all. Rice husk is actually one of the most challenging biomasses. The TEO furnace has been used to burn wood waste and corn cobbs before. If you got a specific biomass, we'd be happy to advise you if we have experience with it, or if we need to do some testing in order to determine if the biomass is suitable for our solution.

How much electricity does it produce?

There is a wide range of modules available dependent on the fuel source (biomass) available/used. The smallest module provides 10kW and the largest 160kW of power. Larger power demands would mean more modules. TEOPOWER also produces waste heat that can be used for drying or generally for generating hot water.

Does it work off grid or only when connected to the grid?

TEOPOWER can operate both off grid and connected to the grid. If your facility is connected to the grid, TEOPOWER provides additional power produced from your waste, which will reduce your power bill. If you don't have access to the grid and use a diesel engine, TEOPOWER will synchronize with the diesel engine. We will work with you to ensure that the CraftEngine output will always be maximized so that fuel savings can be maximized.

Can it adapt to adjustments in power demand?

The CraftEngine allows TEOPOWER to significantly adjust to power demand. Like any other piston engine, the CraftEngine allows TEOPOWER to ramp down power production to a fraction of its nominal power.

What’s the return on investment?

The return on investment depends on many factors, such as avoided power price, complexity of installation in a certain location and also on incentives given or not given in a certain country. Generally, we can achieve payback periods of 1 – 5 years, depending on the above circumstances.

Does it run by itself (automated), or is some knowledge of the solution required?

The solution is designed to run by itself once in operation. The only required activity will be to feed the hoper with biomass and occasionally check to ensure that everything is working within the expected parameters. Unsupervised, TEOPOWER will shut down if there is a problem or certain notifications are not adhered to.

How much space does it require?

A TEOPOWER producing 80kW will require about 10 by 10 metre of space, if arranged with a lot of space. This can be minimized and optimized by arranging the modules to fit into an existing facility. Larger modules need less footprint.

Do I get incentives from the government to install it?

That depends on the country you live in. Most governments offer incentives for renewable energy technologies. We would be happy to work with you to find out what incentives are applicable in your case.

What steps do I take to get one installed at my mill/premise?

Please contact us. We will send you a questionnaire to gather some information about your operation and work with you to develop a proposal that works best for you. Some of the questions we will ask are: What’s the type and amount of biomass available? What is the internal electricity consumption of your facility over time? Where is your facility located?

The Technology

power

TEOPOWER is based on the CraftEngine technology from Viking Heat Engines and the TEO biomass furnace from SuperBrix.

Viking Heat Engines' CraftEngine technology generates energy from heat sources as low as 80 °C (176 °F). By using an automotive piston-type expander developed by AVL Schrick in Germany, the CraftEngine allows for reliable and flexible operation, low capital and maintenance costs and rapid return on investment. 

The CraftEngine offers unprecedented flexibility, adapting easily and quickly to fluctuations in the supply of heat or the demand for electricity.

SuperBrix's TEO cyclonic furnace series have been recognised by the British Foreign Office, the UN and the Colombian Ministry for Development for supporting the move away from fossil fuels by using biomass for drying of rice. 

The functionality of the TEOPOWER is simple: Rice husk is fed into the TEO cyclonic furnace where it is burned using combustion air. The hot flue gas transfers its heat to a hot water loop, which is used to run the CraftEngine and produce power. Any remaining heat can be used for drying.
