• Co-Generation Cogeneration & CHP • Cogeneration through combined heat and power (CHP) is the simultaneous production of electricity with the recovery and utilization heat. Cogeneration is a highly efficient form of energy conversion and it can achieve primary energy savings of approximately 40% by compared to the separate purchase of electricity from the national electricity grid and a gas boiler for onsite heating. Combined heat and power plants are typically embedded close to the end user and therefore help reduce transportation and distribution losses, improving the overall performance of the electricity transmission and distribution network . For power users where security of supply is an important factor for their selection of power production equipment and gas is abundant, gas-based cogeneration systems are ideally suited as captive power plants. 2/19/2014 Engr.

Co-Generation 2/19/2014 Engr. Mohammad Imam Hossain Rubel, rubelduet04@gmail.com

Co-generation System Efficiency • Gas engine combined heat and power systems are measured based upon the efficiency of conversion of the fuel gas to useful outputs. The diagram below illustrates this concept. Firstly the energy in the fuel gas input is converted into mechanical energy via the combustion of the gas in the engine’s cylinders and their resulting action in the turning of the engine’s crankshaft. This mechanical energy is in turn used to turn the engine’s alternator in order to produce electricity. There is a small amount of inherent loss in this process and in this example the electrical efficiency of the engine is 40% Heat Sources from a Gas Engine • • • • • • The heat from the generator is available in from 5 key areas: Engine jacket cooling water Engine lubrication oil cooling First stage air intake intercooler Engine exhaust gases Engine generator radiated heat, second stage intercooler 2/19/2014 Engr.

Tri-generation • Tri-generation or combined heat, power and cooling (CHPC), is the process by which some of the heat produced by a co-generation plant is used to generate chilled water for air conditioning or refrigeration. An absorption chiller is linked to the combined heat and power (CHP) to provide this functionality. Quadgeneration takes this process one step further with the addition of systems to purify carbon dioxide from the engine exhaust. Benefits of tri-generation • • • • • • • • There are a number of benefits to tri-generation including: Onsite, high efficiency production of electricity and heat Reduced fuel and energy costs Lower electrical usage during peak summer demand Engine heat can be used to produce steam of hot water for onsite use Significant reductions in greenhouse gas emissions No harmful chemical pollutants since water is used as the refrigerant Beneficial for improving building’s energy efficiency ratings such as Green Star and NABERS in Australia • 2/19/2014 Engr. Mohammad Imam Hossain Rubel, rubelduet04@gmail.com

Tri-generation Tri-generation systems supply energy in three forms: •Electricity •Heat •Chilled water Absorption chillers provide an economical and environmental alternative to conventional refrigeration. Combining efficiency, low emission power generation equipment with absorption chillers allows for maximum total fuel efficiency, elimination of harmful refrigerants and reduced overall air emissions. There are a number of different configurations of CHP units where refrigeration can be derived 2/19/2014 Engr. Mohammad Imam Hossain Rubel, rubelduet04@gmail.com

Quad generation Quad generation systems are some of the most advanced gas engine driven power plants in the world. Quad generation encompasses the features of a tri generation system, with combined electricity, heat and cooling but in addition includes the recovery of carbon dioxide from the exhaust gas. This carbon dioxide is scrubbed and can be used in industrial process or offers the potential for carbon sequestration. Benefits: • • • • Potential for low or zero carbon emissions Reduced operational costs versus separate purchase of electricity, heat, cooling and carbon dioxide. Uses all potential resources from gas utilization Has a wide range of potential applications Uses: • • • • Carbon dioxide can be used for a number of purposes including: As a growth enhancer in plants Food industry Industrial processes 2/19/2014 Engr.
