in this paper, the amount of wasted heat from different parts of a 12 liter compression ignition engine and their potential for waste heat recovery were investigated. then, two-stage configuration of organic rankine cycle was introduced for simultaneous heat recovery from exhaust gases and coolant. finally, parameters like hybrid generated power, engine thermal efficiency and brake specific fue...

This two-part paper assesses four strategies for energy recovery from municipal solid waste (MSW) by dedicated waste-to-energy (WTE) plants generating electricity through a steam cycle. The feedstock is the residue after materials recovery (MR), assumed to be 35% by weight of the collected MSW. In strategy 1, the MR residue is fed directly to a grate combustor. In strategy 2, the MR residue is ...

In this paper, the method of rationally determining the system structure and operational strategies is proposed for the energy supply system for a hospital based on the optimization approach. First, energy demands are estimated hourly, daily, and seasonally through one year for the hospital with total floor area of 25,000 m. Second, miscellaneous kinds of equipment are listed up such as refrige...

An industrial plant consists of an input of energy, raw materials and labor and an output of products, waste energy and waste materials. If raw material and labor costs are relatively fixed, a reduction in the plant’s energy costs and waste materials are the two best means of improving profitability. This project specifically evaluates cogeneration opportunities as a means of substantially redu...

This paper presents a study of the national electric power, showing the Brazil consumes electricity in a year and how much you could save if thermoelectric modules were used in some industries and new cars and planes to capture and transformation of residual thermal energy into electrical energy. The conclusion appears really attractive economically, given the fact that many processes generate ...

The design of new dual-purpose thermal desalination plants is a combinatory problem because the optimal process configuration strongly depends on desired targets electricity and freshwater. This paper proposes mathematical model for selecting structure, operating conditions, sizes all system components plants. Electricity supposed to be generated by combined-cycle heat power plant (CCHPP) with ...
