Energy Efficiency Enhancement and Pollution Mitigation in Dual-Fuel Fired Industrial Furnaces through Waste Heat Recovery and Robust Design

Abstract

Atmospheric Air Pollution & Global Warming due to the emission of flue gases in the atmosphere is a major issue that is being faced by the world at present. This is due to the incomplete combustion of fuel, producing unwanted components in the flue gases, which are affecting our environment as well as nature badly day by day. It is extremely important to control pollution as well as global warming to preserve nature. This research paper has tried to discuss the cause of the exit of hot flue gases to the atmosphere and recovery of the same by controlling the exit of hot flue gases to the atmosphere. This can be controlled by the complete combustion of fuel as well as by converting the heat into energy. The equipment is installed on the furnace to recover heat losses as well as complete combustion. Ideally, industrial furnace efficiency is considered to be 30 percent for design calculations, which indicates that almost 70 percent of energy is being wasted. The combustion system is designed to achieve the required temperature with better temperature uniformity inside the combustion chamber. Automation by Auto ignition and Auto temperature control system is done for the safety and quality of the final product derived from the system. Hence, it is necessary to enhance the furnace efficiency for energy saving. This will also contribute to pollution control and global warming. An industrial furnace has a major role in the Iron and Steel Industry, Power generation, Ferrous and non-ferrous metals and alloys melting, Heat Treatment, and many more applications that consume maximum energy production globally. Hence, the energy-saving focus is required in this category. Energy-saving will not only enhance efficiency but also contribute to controlling pollution and global warming, too. Optimizing the furnace design by a robust design concept can help the end user achieve complete combustion. This will preserve nature for the next generation.
