“…The possibility of using the heat to supply DHNs is mentioned but not analysed in detail. Fang, et al [8] compared the amount of heat rejected by energy-intensive industry and demanded for DHNs in China while [3] conducted a similar study at a greater level of detail for the city of Hamburg, Germany. In both of these studies, it is suggested that the overall ratio won't capture the situations in which the heat cannot be practically used and the need for spatial and temporal considerations is identified.…”

“…So, efficient energy management and data collection mode will make the advantages and benefits of waste heat recovery more visible and convincing for others. However, in Germany, the rules of data protection are so strict for the sake of trade secrets that most industrial waste heat data are not available directly from industries, so reliable estimation methods could be an effective alternative for calculating the amount of available waste heat indirectly [65]. For EU 27, the new heat roadmap was proposed by considering the recovery of surplus heat from power plants, industries, and waste incineration and re-injecting it into a network of DH, which will increase the proportion of reused waste heat in the total amount of energy consumption in Europe [2].…”

“…This sets a good example for other countries. However, it is also a fact that the total amount of energy consumption in developed countries is high which makes the contribution of industrial waste heat for saving primary energy rare especially in the case that the industrial waste heat is considered for the supply of heating or hot water to residential users [65]. Generally, the traditional energy system needs to be supplemented to fulfill the energy demand.…”

Low-temperature industrial waste heat is an important heat source for industrial processes and utility services to reduce the consumption of fossil energy as well as lower the risk of global warming. In this article, a review of waste heat recovery e a critical solution of waste energy disposal is made in order to show the current status of heat recovery potentials and the possible technologies used industries. The concept of industrial waste heat is defined, potential sources of waste heat from industries are identified and conclusions are drawn. Then, the technologies available for waste heat recovery are illustrated in terms of heat pumps, heat exchangers, heat pipes, boilers, refrigeration cycles, power cycles and heat storage according to the transfer mode of waste heat within the recovery process. The waste heat opportunities both in developed and developing countries are discussed in order to determine the possible benefits of heat recovery as well as to make a general survey of the development of heat recovery technologies globally. Research of typical applications of industrial waste heat recovery in Asian countries and especially in China is overviewed to show the performance of this engineering in practice.

“…The potential of this new technology (fourth generation DES) to utilize low-grade waste heat (<100 • C) in DES has been demonstrated to be technically and economically feasible (Connolly et al 2014, Brückner et al 2014. European national studies indicate that 31% of total European building heating demand can be technically supplied by waste heat .…”

Utilizing low-grade waste heat from industries to heat and cool homes and businesses through fourth generation district energy systems (DES) is a novel strategy to reduce energy use. This paper develops a generalizable methodology to estimate the energy saving potential for heating/cooling in 20 cities in two Chinese provinces, representing cold winter and hot summer regions respectively. We also conduct a life-cycle analysis of the new infrastructure required for energy exchange in DES. Results show that heating and cooling energy use reduction from this waste heat exchange strategy varies widely based on the mix of industrial, residential and commercial activities, and climate conditions in cities. Low-grade heat is found to be the dominant component of waste heat released by industries, which can be reused for both district heating and cooling in fourth generation DES, yielding energy use reductions from 12%-91% (average of 58%) for heating and 24%-100% (average of 73%) for cooling energy use in the different cities based on annual exchange potential. Incorporating seasonality and multiple energy exchange pathways resulted in energy savings reductions from 0%-87%. The life-cycle impact of added infrastructure was small (<3% for heating) and 1.9% ∼ 6.5% (cooling) of the carbon emissions from fuel use in current heating or cooling systems, indicating net carbon savings. This generalizable approach to delineate waste heat potential can help determine suitable cities for the widespread application of industrial waste heat re-utilization.
