2 CHPsolutions Combined heat and power (CHP) systems from SIEMENS reduce on-site energy costs and greenhouse gas emissions. A standard CHP unit producing lowtemperature hot water at 90 ºC. WHY CHOOSE CHP? With more than 50 years experience in the global CHP (also known as cogeneration) marketplace, SIEMENS has developed a strong reputation for delivering energy cost savings and emissions reductions through the design and application of systems for CHP, as well as combined cooling, heat and power (CCHP, also called trigeneration). As a partner to commercial, industrial and municipal energy users worldwide, we are committed to delivering energy savings through cost-effective energyefficiency investments with predesigned, factorytested, fully packaged CHP systems. CHP is ideal for building applications such as: Hospitals Colleges and universities Data centers Commercial complexes R&D laboratories Municipal facilities It is also ideal for industrial sectors including: Pharmaceutical and medical manufacturing Chemical manufacturing Textiles manufacturing Food processing Rubber and plastics manufacturing Waste treatment Agriculture/horticulture Drying processes such as ceramics or automotive paint shops ENVIRONMENTAL FRIENDLINESS Based on the total energy generated, cogeneration plants typically cut NO x and CO 2 emissions by almost 50 percent compared to thermal power plant/boiler systems, while complying with the strictest emissions regulations. PROFITABILITY Cogeneration makes sense for processes where the electricity and most of the heat energy produced by the cogeneration module can be used efficiently. To maximize profitability and to reduce fuel and electric power costs, the performance of the cogeneration module and the availability and quality of maintenance and repair services should all be considered. Governments of most developed countries recognize that cogeneration is the most efficient and least-polluting way to extract as much of a fuel s energy as possible, so regulations for these systems are generally favorable. The SIEMENS engine and CHP manufacturing facility in Zumaia, Spain. 1 Energy Efficiency SIEMENS offers cogeneration or trigeneration energy recovery systems which save up to one third of the primary energy coming from natural gas, biogas or diesel. 2 Power Generation Distributed energy is an effective solution to bring energy where it is most needed and most difficult to obtain. Distributed energy centers located in isolated areas have autonomous systems and do not require services of a traditional power plant. They use diesel, biogas or natural gas as the primary source of fuel. 3 Bioenergy SIEMENS creates solutions for energy recovery from gases generated in water treatment plants, landfills, food industry, forest and agricultural waste, and animal waste on farms. 4 Marine We develop propulsion systems, propulsors, engines, auxiliary engines and reduction gearboxes for different types of ships, to the satisfaction of both skippers and owners, while maintaining strict emission levels. 2

3 PERFORMANCE Our cogeneration plants are built to perform. The SIEMENS engine s combustion chamber extracts the maximum energy from the fuel, while the latest electronic ignition and carburetion control technology continuously fine tunes the operation to maintain efficiency as the gas quality changes. On the electrical side, heavy-duty alternators further contribute to the efficiency. CHP OPERATION AND MAINTENANCE Continuous monitoring and appropriate maintenance are essential for the reliable and efficient operation of a CHP system, so SIEMENS offers comprehensive support, including: Remote 24-hour monitoring Monthly reports detailing system availability and performance Aftermarket support customized to client requirements Comprehensive maintenance contracts are available that provide full service for both scheduled and unscheduled outages. All necessary engineering and consumable spare parts are included, and the SIEMENS operating and reporting process ensures minimum cost for all maintenance activities. Availability guarantees with penalty and bonus provisions can also be included. CHP REFURBISHMENT Have an older CHP system? Site operations could have changed since it was designed and implemented, which means the system is not operating at its full potential. To ensure you re still getting the maximum possible energy savings from your CHP assets, consider our three-step update service: 1. INVESTIGATION REPORT For a nominal consultation fee, SIEMENS performs a detailed investigation of your CHP system, its current effectiveness and its potential for improvement. 2. REHABILITATION PROPOSAL If the potential improvements look promising, SIEMENS can complete a more detailed cost and design analysis and provide a fixed price for system upgrades and improvements. There is no charge for this service if the recommendations are implemented. 3. PROJECT IMPLEMENTATION Our engineering team will upgrade your CHP system and hand over a fully commissioned and performance- tested plant, complete with options for ongoing service and maintenance. SIEMENS engines offer reliability, high efficiency and easy maintenance, making them a perfect fit for your CHP installation. SIEMENS CHP solutions are tailor made to meet a wide range of client needs and applications. A CHP system from SIEMENS can produce more heat energy and power while reducing losses. 3

By matching your energy requirements with the most efficient, flexible and effective CHP systems, SIEMENS is able to deliver total energy solutions that optimize operating efficiency and lower total lifecycle costs. From the selection of the basic approach to the design of the application interface, SIEMENS consistently helps clients gain additional value from their energy assets. Individual CHP systems range from approximately 150 kwe to 2.5 MWe (larger capacities available with the Multiple CHP units offer a solution capable of matching a site s varying thermal and electrical demands. installation of multiple systems). COGENERATION WITH HOT WATER PRODUCTION A cogeneration system produces hot water by recovering heat from the engines cooling circuits and exhaust gas systems. Hot water produced by cogeneration can be used for washing and heating in service sector applications (e.g., hospitals, hotels, sports centers, swimming pools, etc.) as well as many industrial processes. 4

5 TRIGENERATION FOR AIR CONDITIONING OR PROCESS COOLING With seasonal temperature variations and the possibility of process cooling requirements, the heat produced from cogeneration systems may not always be required by a host facility. With the addition of an absorption refrigeration device, it is possible for the cogeneration system to deliver a third output in the form of chilled water or conditioned air. A system with electricity, heating and cooling outputs is known as a trigeneration system. SIEMENS has extensive experience in the design and implementation of customized trigeneration equipment. AIRCOGEN PRODUCTS COGENERATION WITH HEATED AIR PRODUCTION A unique form of small-scale CHP directly heats air by using the latent and generated heat from the power generation CHP package. The technology used is similar to that of a modular packaged CHP plant, but the equipment package includes the heated air stream as well as integral heat exchangers and air-handling equipment. At peak performance, this system can achieve 95 percent efficiency. Suitable applications include distribution warehouses, process drying applications, space heating, and other applications where hot air is required on a continuous basis. COGENERATION IN GREENHOUSES Cogeneration reaches its maximum potential when applied to greenhouses, since all of the CHP outputs (heat, CO 2, electricity) can be fully used. SIEMENS has installed more than 300 greenhouse systems throughout the U.S. and Europe, including Spain, The Netherlands, Belgium, Italy, Germany, and many other countries. Natural gas-operated cogeneration modules are a very profitable investment for greenhouses. The electric energy they generate can be sold to power utilities at a reasonable price, and the heat and carbon dioxide from the exhaust promote plant growth. Not only that, but new cogeneration laws have made the conditions even more favorable. Our wide range of modules can meet the specific requirements of every greenhouse. 5

6 COGENERATION AT LANDFILLS Biogas produced from the anaerobic fermentation of organic matter in landfill sites is an ideal fuel for power generation. SIEMENS can help you to maximize the revenue-earning poten- tial of your landfill, turning waste gas into electricity and producing heat that could be piped to nearby facilities. COGENERATION FROM DIGESTER GAS Cogeneration systems can be operated on the gas produced from anaerobic digestion facilities such as sewage treatment plants or agricultural waste digesters. Anaerobic digestion produces methane-rich biogas that can be treated and used as fuel in special-purpose cogeneration modules to produce electric energy for the facility and hot water for the digesters. In warm climates where the process demand for hot water is lower, the gensets exhaust gases can be used for sludge drying. Biogas-fueled engines are also frequently used to directly drive pumps and agitators. The electricity generated from digester gas will often attract government subsidy or electricity tariff benefits in recognition of its significant environmental contribution.
