ORC Organic Rankine Organic Rankine Cycle Cycle Organic Rankine Cycle (ORC) is a key technology for electricity generation from decentralized heat sources. Due to its efficiency and flexibility, unused thermal energy can be profitably utilized using ORC technology with a temperature range of between 90 and 600 C. Areas of application Dürr Cyplan ORC systems can be used with many different waste heat sources. Currently, the most attractive waste heat sources are those available continuously and in which users receive payment for the electricity generated. These sources include stationary combustion engines running on renewable raw materials such as bio-gas plants, gas turbines, or wood-burning appliances. The higher the electricity prices and the greater the availability of waste heat, the faster the investment in an ORC system is amortized.

ORC 70 kw compact module The ORC system The ORC process is a thermal cycle which uses thermal energy to generate electricity. Hot exhaust gases flow from the heat source (e.g. combustion engine) into the ORC module where the working medium is evaporated by heat energy. Steam flows under pressure into a turbo generator where a portion of the heat energy is converted into electricity. Finally, the steam is condensed in a condenser where cooling re-liquefies the steam. The liquid working medium is pumped back into the evaporator. ORC systems are available as standardized compact modules in electrical power performance sizes of 70, 120, 300 and 500 kw. Advantages Electricity generation using residual heat from combustion or production processes Pre-tested compact modules for a broad temperature and performance range High electrical efficiency with minimum power consumption Easy system integration thanks to direct evaporation technology Optional utilization of condensation heat Fully automatic operation and remote monitoring Both high and low-temperature heat sources can be used for power generation. In high-temperature units, the condensation heat can be supplied at a temperature which enables further use and thus combined heat and power operation. 5

CPS Compact Power Compact Power System System The Compact Power System (CPS) is based on gas turbine technology, combining highly efficient power and heat exchanger for decentralized production of electricity and heat by converting energy from low calorific gases or for cleaning solvent-laden air. Areas of application The CPS systems are versatile. For example, CPS systems can be used for steam generation, heating, air conditioning, drying, CO 2 fertilization, or in combination with a downstream ORC process or heat pumps. CPS can operate with low emissions on a wide range of fuels such as natural gas, biogas, or low calorific gas and liquid fuels such as diesel or methanol. 6

The technology Air taken in is compressed in the micro gas turbine and then normally preheated by a recuperator using the thermal energy of the exhaust gas. The compressed air and fuel are burned together in a combustion chamber. The combustion gases drive the turbine, which is installed on the same shaft as the electricity generator and the compressor. The exhaust gas from the micro turbine is used for waste heat recovery processes. Micro turbines are characterized by their compact design, high speed, low pressure conditions, and low noise emissions. Advantages Efficient use of fuel Constant exhaust gas flow at a set temperature level Long service intervals: 6,000 8,000 h Low maintenance costs: 0.6 1.5 per operating hour High fuel flexibility Very low NO x and CO emissions; no exhaust aftertreatment required Overall efficiency of 90 % is possible Remote monitoring and remote maintenance CPS for drying processes 7

LATHERM Mobile heat Mobile heat accumulators accumulators The LaTherm latent heat accumulator is an integral part of the LaTherm heat transport system, a street-based analogue of local and district heating networks. The heat transport system The LaTherm heat transport system consists of the LaTherm latent heat accumulator and the docking stations that connect to the heat source and to the heat consumers installations. The heat is fed in and out of the latent heat accumulator via the fixed docking stations that are installed at the source and consumer facilities. The system is designed to handle high volumes of heat. Typically, each heat accumulator is discharged and recharged over 100 times per year. The mobile heat accumulator The low-maintenance LaTherm latent heat accumulator is a 20-foot container that has been reconditioned and adapted for use as a mobile heat accumulator. The storage medium, sodium acetate trihydrate, used in the LaTherm latent heat accumulator enables the storage and transport of large volumes of heat. Sodium acetate trihydrate is a non-hazardous phase-transformation substance that is also used in freely available hand-warming pouches. LaTherm latent heat accumulator Series 4 8

LaTherm heat management software The storage capacity of the mobile heat accumulator is up to 2.5 MWh with full charge and deep discharge. In the typical application case, 2 MWh are stored. The charge takes 12 hours, while the discharge takes no more than 24 hours under optimal conditions. Target group Any company that produces unused residual heat, for example a waste incineration or bio-gas plant, can become a regional heat supplier using the LaTherm heat transport system. The heat source should provide at least 250 kw thermal output at minimum 95 C. Heat customers are high-volume consumers, whose heating systems work optimally in the low temperature range. Examples include swimming pools, logistics centers, schools, and office buildings. Heat consumption should be at least 500 MWh. Remote monitoring The mobile LaTherm latent heat accumulator is equipped with a heat meter, which collects billing-grade heat consumption data. An integrated electronic device sends this heat consumption data to the LaTherm data center. Here, the data is available to the operators of the mobile heating network for billing purposes, but also for planning of transport logistics. Advantages Reduction of fuel consumption Long-term predictability of heat costs Generation of usable low-carbon heat from waste heat Regional heat supply on the doorstep Visible, positive public-image solution 9

»» thermeco 2 HHS 1000, heating capacity 1,000 kw awarded the Kältepreis (award for environmentally friendly innovation in refrigeration technology) by the German Federal Ministry for the Environment THERMEA THERMEA High-temperature heat pumps, refrigerant units, and compressed-air refrigerant dryers using environmentally friendly refrigerant CO 2 Technology State-of-the-art heat pumps and refrigerant units for applications in industrial and building automation systems. Heating-water temperatures of up to 90 C can be reached with the proven thermeco 2 systems. This paves the way for many new applications for energy-efficient and sustainable production, particularly in the industrial sector. Sustainable CO 2 refrigerant The use of the natural refrigerant R744 (CO 2 ) renders the thermeco 2 systems absolutely environmentally friendly. CO 2 is climate neutral (GWP = 1) and does not contribute to ozone depletion (ODP = 0). The currently widely used fluorinated refrigerants contribute to the greenhouse effect and so to the acceleration of climate change. Therefore, HCFC refrigerants such as R22, which causes ozone depletion, are only authorized for use until the end of 2014. Other widely used HFC refrigerants are also the subject of controversy and are once again being tested with the coming tightening of the F-Gas Regulation. thermeco 2 systems that work with harmless CO 2, are therefore a long-term reliable alternative. 10

thermeco 2 high-temperature heat pumps and refrigerant units The thermeco 2 HHR / HHS series serves a heat output range from 45 to 1000 kw. The refrigerant version can ensure temperatures down to -10 C.
