A more rapid estimation of this heat can be done by using a formula developed by Zur Strassen (1957) which gives good agreement with basic calculations. This formula is: Qth = 2.22A + 7.64C – 5.116S – 0.59F Where Qth = theoretical heat of the formation A, M, C, S and F are the percentage of AW3, MgO, CaO, SiO2, and Fe2Os in the clinker.
Capacity has increased from as low as 50 tpd to as high as 12000 tpd from kiln. Heat consumption reduced from 1400 kcal/kg to 670 kcal/kg of clinker. Specific heat consumption of various kiln systems is tabulated (Table 2) below to assess the progress in the development of clinkerization technology. ... in a reactor like rotary kiln, therefore ...

approximately cylindrical flame. Heat transfer from this flame and the hot combustion gases that flow up the kiln dries, heats, and calcines the counter-flowing lime solids. Rotary lime kilns in the pulp and paper industry range in size from 7 ft (2.1 m) in diameter by 175 ft (53 m) long to 13.5 ft (4 m) in diameter by 400 ft (122 m) long.
Convective heat transfer in a rotary kiln was studied as a function of operating parameters. The experiments were carried out in a steel kiln of 0.19 m in diameter and 2.44 m in length. The operating parameters covered included gas flow rate, solid throughput, rotational speed, degree of solid holdup, inclination angle, particle size and temperature. To minimize radiation effects, air was used ...
Sep 01, 2015 Heat balance shows that total 62.342 Gcal [Eqs. and ] of energy is consumed in kiln from which 35.35 Gcal [Eq. – 8.0] is lost in the form of sensible heat and only 26.992 Gcal is utilized in the process which is 43.3%. The major fraction of total energy is lost to the atmosphere through waste gas exiting from the rotary kiln.
