“…Heat pipes (Figure 10) can be used to recover waste heat from sources at up to 600 • C [120] or, according to some sources [12], even 1000 • C, but the selection of the working fluid inside the heat pipe as well as the material of the pipe must reflect the actual operating conditions [121]. For example, liquid metals must be used when operation under high temperatures is required [122].…”

“…The main weakness of heat pipes-primarily in cases when the working medium is solid at ambient temperaturesis their "frozen" startup [122]. The application of heat pipes is common not only in thermal management (typically in the IT sector or the automotive or power generation industries) [120], but also in glass production or solar concentrators [48]. Major benefits of heat pipe application in terms of CO2 emission savings have been observed in the iron and steel and (petro)chemical industries and in cement production [12].…”

The efficient utilization of waste heat from industrial processes can provide a significant source of energy savings for production plants, as well as be a driver of sustainable operations and the abatement of emissions. Industrial waste heat usually is contained in liquid or gaseous outlet streams. Although the possible ways to utilize waste heat are discussed in a wide variety of papers, these either provide only a general overview of utilization options and opportunities or focus on a narrow range of industrial processes. The aim of the present paper is to discuss the practical aspects of waste heat utilization in the European Union so that the reader can gain perspective on (i) the thermal classification of waste heat, (ii) liquid and gaseous waste streams and their typical temperatures for industrial use cases, (iii) the technical, economic, physical, and environmental aspects barring full utilization of the available waste heat, (iv) waste heat sources in various industries, and (v) standardized equipment and technologies applicable to industrial waste heat utilization, including their advantages, disadvantages, and weak points.
