Design of Pusher Type Continuous Reheating Furnace
Abstract: With the rapid development of China's national economy, especially in recentyears, increasing demand for energy exploitation of our domestic energy depleting,increasingly serious energy crisis, which also had a serious environmental crisis, but China'senergy use is still lagging behind, especially in the industrial furnace, while China is themajor industrial countries and the world of processing plants, industrial furnaces annuallyspent large amounts of fuel, improve the fuel utilization rate of industrial furnaces, hasbecome an important way of saving energy and important task of the industrial furnacedesign improvements have been listed as the 12th five Year Plan a step by step.Energy-saving and low consumption of industrial furnaces will become the futuremainstream of industrial furnaces, this paper describes the 38 tons of pusher type continuousreheating furnace design, including the calculation of fuel and combustion; billet heatingcomputing; furnace size; bottom the design of the water-cooled components; furnacemasonry materials and sizes to determine the steel frame structure; furnace heat balance andthe determination of the amount of fuel; heat exchanger design, the design of piping systems;smoke control system design.
