Equipped with one of the best electric arc furnace waste heat recovery boiler brands, JSDJ Heavy Industry Co.,Ltd is one of the professional quality eaf off gas heat recovery system, waste heat recovery for eaf, eaf waste heat recovery system manufacturers in China.
Electric Arc Furnace Waste Heat Recovery Boiler
Steel & iron making accounts for 12% ~ 15% of the entire domestic energy consumption annually, and around 10% of this huge production comes from EAF (2009). The dust-laden flue gas temperature is approximately 1000℃ ~ 1450℃ which has been traditionally treated by series of water-spraying to lower its temperature down to 130℃. This traditional method requires extra energy input and leads to a tremendous water wastage, for which a quality waste heat recovery system is a responsible choice to make.
Both flue gas quantity and temperature emanating from the EAF fluctuate along with the smelting cycle. Moreover, gas contains a large portion of dust particles, rendering heat surface (heat exchange surface) susceptible to fraction. Our heat surface area employs a unique multi-free-end-surface design, meaning that the heat surface is able to stretch flexibly within a safe interval as the heat expansion frequently takes its place. Our boiler is also designed with optimal flue gas velocity to ensure the long lifespan of the entire heat surface. The average investment recovery period is 3 to 4 years.
