Industrial applications that require steam for their end-use generally utilize boilers are typically oversized, citing operations flexibility. Similarly, gas turbine-based power plants corroborate a turbine system may eventually relieve the usable exhaust into atmosphere. This study explores economic and technical feasibility of topping cycle combined heat (CHP) system. It does so by leveraging...

Urban systems account for about two-thirds of global primary energy consumption and energy-related greenhouse gas emissions, with a projected increasing trend. Deep geothermal energy and woody biomass can be used for the production of heat, electricity and biofuels, thus constituting a renewable alternative to fossil fuels for all end-uses in cities: heating, cooling, electricity and mobility. ...

The simultaneous generation of steam and power, which is commonly referred to as cogeneration, has been adopted by many sugar mills in India to overcome the power shortage. It becomes an increasingly important source of income for sugar factories. The problems faced by the sugar mill industry arise mainly due to failures of either the complete system or some specific components during the cogen...

The absolute necessity of a stable and uninterrupted power supply within hospitals makes many of these facilities uniquely suited to cogeneration plants. Hamilton Health Sciences recently completed the largest hospital cogeneration project ever undertaken in the country. Spanning three acute care hospitals and generating a combined total of 22.75 megawatts of electricity, Hamilton Health Scienc...

The purpose of the paper is to analyze the transient stability of an industrial cogeneration system in Hsin-Chu Science-Based Industrial Park using ETAP software. The cogeneration system is installed two 161kV/161kV high-impendence transformers with tap-changer to connect with TPC for decreasing the short-circuit fault current and increasing the fault critical clearing time. The transient stabi...

In the case of cogeneration, allocation operation costs has a particularity specific to joint production heat and electricity from same primary energy source. The cost is also influenced by demand conditions faced products, prices must be sufficient for both products remain profitable competitive with other power generation alternatives in respective markets. Therefore, choice methodology marke...

In the first part of this work, combined heat and power (CHP) criteria pertaining to energy, exergy, environmental (pollutant emission) and economic aspects, have been investigated and compared. Although the constraints in legislation usually refer to energy efficiency, primary energy savings and greenhouse gas savings, other criteria should also be taken into account in order to obtain a bette...

The paper deals with the design problem of natural gas cogeneration systems. Despite its complexity, this design problem subjected to several constraints is properly solved by humans, which suggests the use of artificial intelligence (AI). Moreover, the design process is strongly based on knowledge that experts have in a domain, so that the AI techniques known as knowledge-based systems (KBS) a...

Alcoholic fermentations were performed adapting the technology to exploit the residual thermal energy (hot water at 83-85°C) of a cogeneration plant and to valorize agricultural wastes. Substrates were apple, kiwifruit and peaches wastes and Corn Threshing Residue (CTR). Saccharomyces bayanus was chosen as biocatalyst. The fruits, fresh or blanched, were mashed; CTR was gelatinized and liquefie...

Process utility systems consume fuel, generate power and distribute steam. The heating and cooling requirements of the site dictate the site-wide fuel demand and cogeneration of the utility system. New tools have been developed for the design of cogeneration and total site utility systems. In addition, utility systems are always designed with significant spare capacity to allow for the constant...
