Abstract: Objective: This paper examines strategies for waste heat recovery, focusing on high-temperature waste gases produced by boilers, kilns, ovens, and furnaces. Methods: The design and operation of waste heat recovery boilers (WHRB) are explored including fume condition, technical parameters and water supply quality with an example of a system that recovers heat from off-gases to generate steam. Results: WHRB system is highly efficient, generating 12 tons of heat per hour in the form of steam by recovering waste heat from off-gases. The efficiency of such a system typically depends on the temperature and volume of the waste gas, the quality of the heat exchanger, and the design of the WHRB. Conclusion: By capturing waste heat, industries can save substantial amounts of primary fuel, reduce energy consumption, and lower operational costs. Additionally, the paper demonstrates the positive environmental impacts of such systems, including reduced energy usage and lower emissions, contributing to enhanced sustainability and energy efficiency in industrial operations.
