ABSTRACT

The experimental system of waste heat utilization exchanger, installed in the tank calcined furnace, was built. The heat transfer coefficient of heat exchanger, temperature distribution of calcined petroleum coke and utilization ratio of waste heat were systematically studied. The results showed that with the increase of calcined petroleum coke velocity, the heat transfer coefficient of heat exchanger increases. The utilization ratio of waste heat increases first and then decreases. With the increase of water velocity, the heat transfer coefficient of heat exchanger increases. Compared with light-andtube heat exchanger, the heat transfer performances of fin-and-tube heat exchanger increase. The average steam producing rate and the average utilization ratio of waste heat increase. The average temperature of calcined petroleum coke in heat exchanger outlet decreases. The uniformity degree of temperature in heat exchanger outlet increases.
