DEVELOPMENT STATUS
1998 – The first ORC-module for CHP-application in combination with a biomass combustion plant has been installed in Europe.
2008 – More than 120 ORC-modules have already been in operation.
ORC-modules are suitable for power generation from geothermal heat, solar heat, biomass and from industrial waste heat, by using different organic fluids.
MAXXTEC´S PORTFOLIO
ORC-modules with capacities between 300kWel and 2400kWel suitable for CHP-applications, heated by biomass, industrial waste heat or solar thermal energy
ORC-modules < 300kWel are tested actually
More than 120 ORC-Modules for high temperature applications are successful in operation

SIMPLIFIED DELINEATION OF A COMBINED HEAT AND POWER GENERATION PROCESS
Description of a combined heat and power generation process using ORC technology
Power plants using ORC technology generate electricity and heat from various heat sources like solid biomass, industrial waste heat and solar thermal energy

The ORC technology is primarily used in power plants with capacities of up to 2,5 MWel
DESCRIPTION OF A COMBINED HEAT AND POWER GENERATION PROCESS
1.
2.
3.
The process of generating electricity and heat from solid biomass and industrial waste heat consists of three separate stages:
Solid biomass is fed into a combustion chamber and burned or industrial waste is used Hot exhaust gases are emitted as a direct by-product of the combustion process and rise to the exit valve of the combustion chamber These exhaust gases, whose temperatures can reach more than 1000 ºC, are then released into a heater, a steel encasement above the combustion chamber housing coils of tubes containing thermal oil. At this point, the second stage of the process begins:
As the tubes are exposed to the hot exhaust gases, the thermal oil inside the tubes is heated to temperatures above 300 ºC This heated thermal oil acts as an energy conveyor and transfers the heat through the tubes to a specific electricity producing module ("ORC module"), which triggers the third stage of the process, the so-called "Organic Rankine Cycle” process:
At this stage the heat from the thermal oil is used to heat a high molecular mass organic fluid (the "ORC medium") contained inside a separate closed loop in the ORC module The ORC medium is heated until it turns into vapour inside the ORC module. The vapour is then fed into a turbine where it expands and drives the turbine, which in turn drives a generator by rotating a shaft connected to the generator As a result, the generator, once rotated, begins to produce electrical energy. After passing through the turbine, the ORC medium is condensed, and the ORC process starts again Residual heat generated by the condensation process of the ORC medium is diverted to a so-called heat consumer (e.g., a long-distance heating providing network, drying equipment, air conditioning equipment, water preparation systems or other industrial processes)

FAVORABLE TECHNOLOGICAL CHARACTERISTICS OF ORC VS. STEAM TURBINE
The ORC process is economically & technologically the most interesting solution for small-scale applications.
Source: Company data
Comparison ORC vs. steam turbine (3)
Economic viability: - Higher efficiency on small-
scale temperature level (< 500 °C) and on CHP
operation mode - Reduced requirement of
operating personnel - Reduced installation costs
and time due to integrated and standardized design, pre-assembled on a base frame
- Automatic start-up and shut-down operation and fully automatic service with low maintenance and operational costs
Technological advantages: - No water treatment necessary and therefore no use of chemicals
- Closed circuit using an organic working medium with low boiling point instead of water
- The use of a vapour phase organic fluid allows the use of low temperatures for electricity generation
- No super heater is required which is one of the most critical parts in steam power plants
- Better part load efficiency, part load operation possible down to 15% of the nominal load
Flexibility: - Reduced project-engineering requirements due to system integration
- Standardized systems and combinations with heat transfer system, consumers etc.
- Flexibility for primary temperatures and different kinds of energy sources due to the possibility to use different ORC fluids

Competitive technologies for solid biomass
ORC technology particularly distinguishes itself from other technologies due to favourable technological characteristics in the small and mid scale biomass co-generation
Currently the steam-power process is the only long-term approved technology being commercialized for several decades; however R&D is still ongoing with respect to specific features
ORC technology has achieved a visible break-through in the market; in particular for small and mid-scale applications (0.3 - 2.0 MWel) ORC is the most convenient biomass power generation technology; trend for ORC is approved by the favourable market development since 2004 (amendment of EEG); bearing further potential as it is expected that the ORC techno-logy will also penetrate higher-scale as well as in lower-scale power applications
CHP plants with Stirling engines are close to market maturity but still require in-depth economical and technical research efforts to improve their limited status of commercialization
Further technologies are rather in the experimental stage; missing market maturity is going along with technical risks and high investment costs
