• Keeping kiln shell temperatures under control

Jun 01, 2017 Under the assumption that the air blown to the complete kiln can be heated up by 40 C, one can dissipate roughly 2MW of thermal power by using 150,000m 3 /hr of air (Figure 2). The same amount of thermal power can be dissipated with 0.9L/s of water, just 3.2m 3 /hr water for a complete 60m kiln (Figure 3)

May 18, 2017 The velocity pressure is used to calculate air velocity. Total pressure Total pressure is the sum of the static and velocity pressure. Velocity pressure and static pressure can change as the air flows though different size ducts, accelerating and decelerating the velocity. The total pressure stays constant, changing only with friction losses. 43
