UNSW Cogeneration A small cogeneration system has been installed in the Unigym building on lower campus to principally serve the heating needs of the indoor swimming pool. What is cogeneration? Most of UNSW's electricity supply comes from power stations around the state, and is ultimately brought to us through Energy Australia's high voltage network. Cogeneration involves the joint production (locally) of two forms of energy from the same source. In our case, the two forms will be hot water and electricity from a natural gas supply. This arrangement significantly increases the standard efficiency of energy transfer, leading to long-term financial savings and greenhouse gas reduction. The system comprises a 185kWe gas fuelled, spark ignition electrical generator set, located in the existing plantroom, in conjunction with a 400kW gas fired hot water generator. The Electrical Generator set is provided with heat recovery from both jacket water and exhaust flue gasses. The heat recovery system is then connected to the existing Pool Heating Water, Space Heating Water and Domestic Hot Water Systems.

INVESTOR INFORMATION Energy Conservation During the next 24 hours, the world will consume the equivalent of 122 million barrels of oil. That energy drives the economic progress that improves the quality of life for people around the world. Energy Efficiency at ExxonMobil Because we consume $5 billion worth of energy each year running our global operations, ExxonMobil takes energy efficiency seriously. A key tool in improving the energy efficiency of our operations is our Global Energy Management System (GEMS). This system helps us understand the efficiency and subsequent emissions impacts of new projects for consideration during the project design stage. Since 1990 our refineries have improved their energy efficiency by nearly 10%. The greenhouse gas emissions saved over this time are equivalent to removing a milion cars from the world's roads. GEMS has helped us achieve these efficiencies as well as identify opportunities to improve by an additional 10%. In 2003, we achieved record performance in energy efficiency across our worldwide refining business and, over the past four years, our U.S. refineries alone have improved at a rate three times higher than industry. Another major source of energy savings has been through the use of cogeneration (often referred to as

Home TME Research Energy ... Topics Cogeneration of heat and power The impact of the implementation of cogeneration in a given energetic context District heating with cogeneration Experimental work on micro-cogeneration The impact of the implementation of cogeneration in a given energetic context In order to evaluate the value of cogeneration, usually static simplified criteria are used, neglecting the entire energetic context and the dynamic interaction between cogeneration and the centralized electric system. Therefore, a dynamic method, based on simulation of scenarios, is proposed. For a given demand for heat and electricity, two scenarios are worked out: a scenario where no additional cogeneration is installed and a scenario where cogeneration is added. To correctly portray the dynamic response of the central power system, simulations are performend with the model PROMIX For cogeneration with high annual use, the static simplified method seems valid. For cogeneration with lower annual use or with strongly fluctuating output, the static method is not valid and the environmentally friendly nature of this kind of cogeneration is less obvious. As a general conclusion, it can be stated that every specific possibility for cogeneration has to be evaluated separately in its own overall energetic context, including the entire electricity generation system.

CHP Technologies Why Does EPA Support CHP? ... Benefits of CHP What Is CHP? Combined heat and power, (CHP) also known as cogeneration, is an efficient, clean, and reliable approach to generating power and thermal energy from a single fuel source. That is, CHP uses heat that is otherwise discarded from conventional power generation to produce thermal energy. This energy is used to provide cooling or heating for industrial facilities, district energy systems, and commercial buildings. By recycling this waste heat, CHP systems achieve typical effective electric efficiencies CHP Technologies CHP technologies are conventional power generation systems with the means to make use of the energy remaining in exhaust gases, cooling systems, or other energy waste stream. Typical CHP prime movers include: Combustion turbines Reciprocating engines Boilers with steam turbines Microturbines Fuel cells For information on the operational characteristics, performance, and environmental impacts of these technologies, please review the

Energy and Central Utilities Cogeneration Plant Cogeneration Plant TCNJ Home Page Last Updated: Cogeneration Plant The Cogeneration Plant consists of one 5.2 MW Solar Turbine dual fuel turbine (natural gas and #2 low sulfur oil); one 6 MW Ideal generator; one Davis duct burner; one ERI heat recovery steam generator (HRSG) with a capacity of 28,000 PPH unfired and 40,000 PPH fired; and two Gardner Denver natural gas reciprocating compressors with lead/lag controls. The cogeneration plant utilizes a Wonder Ware data highway with Allen-Bradley programmable logic controls (PLCs) platform. Turbine The turbine converts chemical energy from the fuel source into mechanical energy. Unlike four-stroke car engines with reciprocating pistons, which use the four combustion processes, combustion; expansion; compression; and exhaust separately, a turbine operates on the Brayton Cycle, which accomplishes the four combustion processes simultaneously. The Brayton Cycle Combustion In the Brayton cycle, a turbine is injected with fuel through fuel injectors. The fuel is combusted, resulting in high temperature in the combustion chamber.

Table of Contents Previous Section Next Section SECTION 10: DISTRICT ENERGY AND COGENERATION: INCREASING THE EFFICIENCY OF ENERGY SERVICES Introduction Cogeneration is a way to provide energy services much more efficiently. This technology can play a key role in the transition to a sustainable energy future for British Columbia. What is cogeneration? Cogeneration is the simultaneous production of electricity and useful heat from one fuel source. It is also called c ombined heat and power . An on-site cogeneration facility could be used, for example, by an industrial plant that requires both electricity and steam for its industrial processes. By combining the production of heat and electricity in one process, the plant can achieve greater efficiency than by separately buying power from an electric utility and heat from natural gas supplied by a natural gas utility. Who cogenerates? In North America, industry operates most existing cogeneration facilities. But interest is also growing in technology to serve residential, commercial and institutional buildings. What is district energy?
