Turboden announces its 100th plant
The 100th ORC turbo generator of Turboden is based on the biomass cogeneration and is part of the municipal energy supplier of Hennigsdorf, in Germany. This is a case of district heating from biomass for the municipal energy supplier with an electric power of 2,2MW and a thermal output of 10MW. Hennigsdorf is a small town of 26,000 inhabitants, which is situated 20 kilometres far away from Berlin. The heat demand of the community is covered trough different sources, which consist of renewal resources as well as fossil gas. This is the 50th plant of Turboden in Germany: it is a 22 CHP plant. "We are really proud to have succeeded in installing a hundred plants Europe wide", says Paolo Bertuzzi, Managing Director of Turboden. "Hennigsdorf shows the versatility of our turbo generators as well as the perfect integration of our ORC plant based on biomass cogeneration into a pre-existing district heating net, which is particularly big and fed from non renewable resources. Moreover, Hennigsdorf shows our growing expertise in the production of co-generation plants for always more complex district heating nets".
HRS - high electrical efficiency units
Turboden has developed new models of turbogenerators "HRS", capable of ensuring high performance in terms of electrical efficiency in contexts with a strong presence of agricultural and forest biomass, but with limited ability to allocate the heat. HRS models can operate both in dissipative regime, maximizing the electrical output, and in cogeneration, with the opportunity to provide heat to any seasonal thermal load and making the most of the biomass.
RHI and ITALCEMENTI choose TURBODEN
Turboden was recently awarded two new contracts for ORC modules that will generate electricity by recovering heat from industrial processes. The first refers to an agreement with RHI for a 1 MW ORC module to produce electricity recovering heat from a calcining furnace at the Radenthein sintered magnesite production plant in Austria. RHI is the world leading supplier of heat-resistant refractory products for the metal, cement, lime, glass, non-ferrous, energy, environment and process industries throughout the world. The plant start up is expected for the first half of 2009. The second refers to the important agreement for a process heat recovery ORC plant of about 2 MW signed in August 2008. The client is Ciments du Maroc, a company belonging to ITALCEMENTI Group through Ciments Franšais. The ORC will recover heat from exhaust gas of the clinker furnace at the new production plant in Ait Baha, Morocco. The plant start up is expected for the second half of 2009. The use of ORC technology for recovering waste heat represents one of the most attractive applications of Turboden modules. Potential clients include process industries such as cement, glass, steel and non ferrous industries. Turbogenerators used for heat recovery applications have a power range of 500 kWel to 5 MWel. Heat recovery application from industrial process, as well as from gas turbines and reciprocating engines, have a great potential especially in the current energy and fuel costs scenario.
Advantages of Turboden ORC technology applied to the pellet industries
Turboden has installed 10 ORC plants in the pellet sector all over Europe. At the 16th European Biomass Conference & Exhibition (Valencia, 2-6 June 2008), Turboden presented a paper detailing the market opportunities for installing Combined Heat and Power (CHP) plants based on ORC technology to the pellet industry. The market opportunities focus on the use of ORC technology to supply the heat needed for drying sawdust to produce pellet. The article presents, among other things, the results of an economic feasibility study, comparing CHP plants (ORC units of different sizes coupled with a belt dryer) and traditional heat-only plants (based on belt and rotary dryers) and their suitability to the pellet production process. The article clearly demonstrates that the installation of cogeneration biomass units, based on thermal oil boilers and Turboden ORC units, coupled with indirect belt dryers as heat suppliers for pellets plants, is an economically viable - and indeed preferable option - for the pellet industry. These conclusions are based on the evidence that: plants ranging from 4 t/h pellet production capacity (about 900 kWel from ORC) guarantee a good economic return with an electric energy value of greater than 0.16 Euro/kWh; plants ranging from 8 t/h pellet production capacity (about 1600 kWel from ORC) guarantee profitability for covering the consumption of the pellet-making process with an electric energy value of 0.11-0.12 Euro/kWh. Because additional revenues can be gained from the generation of electrical energy, installing an ORC-based CHP solution within a pellet production plant can reduce the risk connected with increased biomass costs, and means that profit can be generated more easily than using a heat-only solution, even taking into account higher fuel costs. Finally the paper presents a real experience of the 1 MWel Turboden ORC unit installed in Mudau pellet plant (Germany), in operation since October 2006.
