The ceramics industry is renowned for using a lot of energy, particularly heat energy to produce ceramic goods because the roller hearth kiln plays a major role in making ceramic products. but it’s difficult cooling process generates significant waste heat, often releasing it into the environment, so there is a lot of excess heat energy loss. Several industries use heat exchanger systems to recover excess heat energy. In this paper, a double pipe heat exchanger (DPHE) is used to recover excess waste heat from the ceramic industry and also improve that energy in an effective way. This paper provides a theoretical analysis of a double-pipe heat exchanger as well as an experimental setup, methodology, results, and analysis of a heat exchanger designed for a kiln. DPHE technology plays a great role in the ceramic industry by lowering operational costs and energy consumption. In future research, further optimization of the DPHE system could lead to even greater energy efficiency and cost savings for ceramic manufacturers. This novel system of DPHE results that the first test condition achieves greater heat transfer rate than other DPHE condition i.e., approximately 1.33 times higher than others. In comparison, the first DPHE condition 5.69 % superior than third condition whereas 3.33 % than second DPHE condition respectively.
