Abstract:

The aim of this paper is to take full advantage of the waste heat which is being dissipated into the surrounding atmosphere from a diesel engine in which 25.5% by the exhaust gases, 14.1% and 6.3% by air cooler and jacket water correspondingly. A waste heat recovery system is used to recover exhaust energy, waste heat from the coolant system, and released heat from turbocharged air in the intercooler of a diesel engine. By using waste heat from the engines, the efficiency of the combustion process can be significantly improved, manufacturers claim that savings in fuel consumption and fuel cost

Abstract:

In northern China, many thermal power plants use absorption heat pump to recover low-grade heat from turbine exhaust steam due to the irreplaceable advantages of the absorption heat pump in waste heat recovery. In the process of designing a waste heat recovery system, few researchers have considered the relationship between the design power of the heat pump and the actual heating load of the heating network. Based on the heating load characteristics, this paper puts forward a design idea which uses an absorption heat pump to recover waste heat from a steam turbine exhaust for heating supply. T

Abstract:

Flue gas condensation heat recovery technology has a good technical and economic performance in industrial exhaust gas waste heat recovery. Thermal efficiency analysis is the traditional analysis method for the flue gas condensation heat recovery system but it cannot reflect the recovered heat degree. Exergy analysis, which can reflect the recovered energy heat degree, was first applied to the evaluation of a flue gas condensation waste heat recovery system in this paper. The calculation method of wet flue gas exergy is more complex as both a heat and mass transfer is presented. Flue gas waste

Abstract:

During compression, a gas heats up, almost in all cases this heat being wasted, either by cooling the gas because it is too hot for the application, or by storing the gas and letting the compressed gas cool naturally in the storage tank. This paper presents a waste-energy (heat) recovery system from the gases compressed by an oil-free screw compressor. The gases compressed by this compressor have a very high temperature compared to an oil injected screw compressor, due to the fact that the oil used to lubricate the rotors also acts as a heat sink, the oil free variant which is used when you wa

The objective of this study was to determine the best method for waste thermal energy recovery from internal combustion engine (ICE). There are several technologies that can be used to accomplish this objective such as turbocharger, combined turbines, Stirling engine, Seebeck effect and Rankine cycle. Two elements that need to be taken into consideration in order to choose the best technology for waste heat recovery system are the complexity of the system and the method to utilize waste heat energy from engine.

Abstract:

Remote communities that have limited or no access to the power grid commonly employ diesel generators for communal electricity provision. Nearly 65% of the overall thermal energy input of diesel generators is wasted through exhaust and other mechanical components such as water-jackets, intercoolers, aftercoolers, and friction. If recovered, this waste heat could help address the energy demands of such communities. A viable solution would be to recover this heat and use it for direct heating applications, as conversion to mechanical power comes with significant efficiency losses. Despite a few

Modern data centers are playing a pivotal role in the global economic situation. Unlike high-quality source of waste heat, it is challenging to recover the decentralized and low-quality waste heat sourced from data centers due to numerous technological and economic hurdles. As such, it is of the utmost importance to explore possible pathways to maximize the energy efficiency of the data centers and to utilize their heat recovery. Absorption chiller systems are a promising technology for the recovery of waste heat at ultra-low temperatures. In fact, the low temperature heat discharged from data

Organic rankine cycle (ORC) system application on smart agriculture is rather energy efficient in terms of waste heat recovery supplied by ORC. The recovered waste heat, such as from agricultural wastes, changes into the electrical energy produced by the generator of ORC cycle. This energy efficiency supplied by ORC system is crucial for smart agriculture as being not only efficient but also environment friendly which is good for green world and nature. In this study, biogas based regenerative ORC system design is explained as more efficient than simple ORC design due to its better regenerator
