“…As previously mentioned, despite the large availability of solutions for heat recovery applications, the intrinsic features of industrial processes impose serious technical challenges that either prevent the application of WHR units or constrain economic feasibility. Vance et al [12] summarized the pros and cons of existing WHR equipment. However, it must be mentioned here that for heat recovery applications in harsh environments, such as corrosive exhausts or high-temperature heat sources, the availability of technological solutions is limited.…”

“…These concerns have led to limited harvesting of the waste heat potential in industrial sectors, especially at HT. To tackle these limitations, the following research drivers were identified by Vance et al [12]: (i) use of advanced materials to improve heat transfer performance; (ii) increase performance life and/or reduce maintenance cost; (iii) design changes to enable endurance in harsh conditions for different, and possibly previously untested applications; (iv) design changes to provide higher thermal efficiency with a smaller physical footprint or size; (v) cost reduction over better design and manufacturing techniques; and (vi) improved seals to decrease maintenance and/or extend seal life.…”

Industrial processes are characterized by energy losses, such as heat streams rejected to the environment in the form of exhaust gases or effluents occurring at different temperature levels. Hence, waste heat recovery (WHR) has been a challenge for industries, as it can lead to energy savings, higher energy efficiency, and sustainability. As a consequence, WHR methods and technologies have been used extensively in the European Union (EU) (and worldwide for that matter). The current paper revisits and reviews conventional WHR technologies, their use in all types of industry, and their limitations. Special attention is given to alternative “new” technologies, which are discussed for parameters such as projected energy and cost savings. Finally, an extended review of case studies regarding applications of WHR technologies is presented. The information presented here can also be used to determine target energy performance, as well as capital and installation costs, for increasing the attractiveness of WHR technologies, leading to the widespread adoption by industry.

“…Waste heat is available in significant quantities in process industries and this can be harvested using a recuperator. 42 The waste heat is available at 200-870 � C depending on the industry. Convective and radiation type recuperator could be used to harness the waste heat from the process equipment and could be supplied to desiccant wheel for continuous regeneration.…”

The paper presents experimental data and results from a prediction tool for the performance of a desiccant loop cooling system. The experiments are performed under a variety of high humidity and hot ambient conditions and the system performance is described. One of the experimental conditions is typical of many Indian cities and the systems appropriate for those cities are established. A simulation program that can predict the performance of the desiccant loop is developed. The simulation results show that this system can work as effectively as vapor compression air-conditioning for certain ambient conditions whereas it can function as a pre-cooler to a vapor compression system under more severe conditions, resulting in a reduced power consumption. The results presented in the paper give a guideline to practicing engineers as to when a desiccant loop cooling system would be useful. A simple payback analysis and a lifecycle cost analysis shows that a desiccant cooling system with a waste heat recovery recuperator is an economically viable investment.

“…Additional WHR technologies and their application can be found in [21]. Vance et al [22] reported that barriers to the WHR technologies cannot only be seen in the LGH streams, but also in harsh environments (with undesirable chemicals or exhaust gases with temperatures above 650 °C) in industrial processes. The authors presented the potential of WHR in harsh environments as well as the advantages and disadvantages of the WHR systems and concluded that WHR from these streams can lead to excessive maintenance, short equipment life, and safety risks.…”

Adoption of Waste Heat Recovery Technologies: Reviewing the Relevant Barriers and Recommendations on How to Overcome Them

et al. 2022

The wide adoption of heat recovery technologies in industry is hampered by specific “barriers” related to both technical and non-technical issues. This paper attempts to determine these barriers and make recommendations on how to address them. First, a literature review of related material is presented. Among numerous barriers, the main ones identified are (i) lack of information, (ii) lack of technology knowledge, (iii) technology risks, (iv) high initial and running and maintenance costs, (v) lack of financial support and lack of governmental incentives, (vi) size and available space limitations, (vii) lack of available infrastructure, (viii) production constraints and risk of production disruptions, (x) risk of the system negative impact on the company operations, and (xi) policy and regulations restrictions. Then, based on the above, a structured questionnaire on barriers to the adoption of waste heat recovery (WHR) technologies was prepared and issued to a number of industries throughout the European Union. Upon analyzing the questionnaire, an assessment of the importance and negative impact of each of the above-mentioned barriers is made. Subsequently, strategies and recommendations on how to overcome the barriers is reported. These recommendations are hoped to be adopted as far as possible in the packaging, installation, commissioning, and demonstration of new and old WHR technologies.
