“…The heat extraction from RTO is unable to provide sufficient heat energy in the winter at weather temperature average 16°C at Taiwan, which needs compensate with steam from boiler. However, the heat can be reduced in summer, at average weather temperature 29°C, which result in higher exhaust temperature . To estimation, the heat energy required for each tank, the heat equilibrium analysis is performed as shown in Figure .…”

The painting operation is an important process in automobile manufacturing process, which not only consumes considerable amount of energy but also affects the environment through the flue gases emitted during the process. A case study in Taiwan was conducted on developing an innovative low‐temperature recovery technology of waste heat automobile industry. The high frequency welding segment technology was built on the site to extract heat close to an acid dew point. When the ambient temperature is changed substantially, the fins and heat pipes are solidly connected to maintain the performance of the heat exchanger. Moreover, the hot water obtained from the waste heat recovery is delivered to pretreatment heating tank the painting shop directly. By improving the energy efficiency on heat transfer, the proposed recovery technology of waste heat in automobile factory has been justified with having the performance 69% higher than conventional design. In order to reduce the effect of CO2 emission on the environmental impact, the temperature at the end of the flue gases is further decreased from 160°C to 110°C. The cost benefit analysis reveals that the payback year is 2.8 years. The innovative heat recovery technology contributes to energy conservation and environmental sustainability.

“…Yang et al [18] proposed physical and chemical methods to recover waste heat for processing aluminium dross. Pocola et al [19] evaluated the heat recovery system in an aluminium foundry based on a thermal power balance. The proposed heat recovery from waste heat was able to supply more than 25% of the total thermal power of the burners.…”

The purpose of this study is to technically design an aluminium scrap processing machine by utilizing the direct exhaust hot air using a conveyor drying system. The automotive parts manufacturing industries use aluminium, a material that requires large amounts of energy for processing. As a result waste heat energy and scrap aluminium are produced -both could be used for savings and efficiencies. One option is utilizing exhaust hot air for the drying process of scrap material for reprocessing. The technical design of the machine follows four steps: analysing the production flow; calculating the potential energy of utilizing the exhaust hot air; designing the exhaust air utilization system for the washing and drying system; analysing the energy savings and the additional techno-economic value added from the system to reprocess the scrap aluminium chips and powder. Our analysis suggests the core melting process still uses 50% of raw material from ingot, but the other 50% from scrap (20% dry scrap briquettes and 30% dry scrap solids). The added value of the design is the material cost savings from the difference between the selling price of unprocessed scrap material and the price of the raw material purchased.
