  • temperature measurement for cement & lime kilns

    The burning zone is the last stage before the material exits the kiln. A single burner fires toward the approaching material, and precise temperature measurement is important to control the firing of the burner. A PSC 2-color pyrometer is effective for monitoring the burner zone as they compensate for dust that can obscure the sight path

  • temperature measurements in cement manufacture

    Dec 14, 2018 · The Burning Zone Also known as the firing zone, the burning zone is at the lower end of the rotary kiln, where the cement components are heated to about 1,300° C to 1,450° C, forming clinker. Accurate temperature measurements are critical for product quality, environmental performance and kiln lifetime. Temperature Solutions in the Burning Zone

  • the cement kiln

    Basically, this is a long cylinder rotating about its axis once every minute or two. The axis is inclined at a slight angle, the end with the burner being lower. The rotation causes the raw meal to gradually pass along from where it enters at the cool end, to the hot end where it eventually drops out and cools

  • kiln zone! - page 1 of 1 - international cement review

    Aug 09, 2008 · The burning zone of a cement kiln is the hottest part of the kiln, under the flame where the final combination into the clinker minerals takes place. Behind that burning zone is the upper transition zone where the temperatures is rising to that in the burning zone. In front of that burning zone where the clinker has been formed and is about to enter the cooler is the lower transition zone

  • cementkilns: design features ofrotary kilns

    The early commercially successful rotary kilns in Britain were nearly all "straight" cylinders, the exceptions being those at Norman (1904). Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends. Among new installations from 1909 to 1914, only 15 out of 44 were "straight", the rest having enlarged …

  • factors affecting calcination quality ofrotary kiln

    When we burn the kiln, we will find that the calcination of the kiln is affected by some aspects. So, let's look at the factors that affect the calcination quality. 1. One of the factors that affect the calcination quality of electric rotary kiln is temperature. Generally, the temperature of calcination zone should be controlled at 1250-1300

  • burning zone temperature estimation of rotary kiln using

    Burning Zone Temperature Estimation of Rotary Kiln Using Flame Image Analysis in Cement Plants Abstract: In a cement plant, the most important and critical part is the rotary kiln which is a large cylinder with a length of about 60-65 meters and a diameter of around 4.5 meters. The kiln is rotated by a powerful electrical motor

  • dalmia - rotary kiln

    The physical transition zone is that portion of the kiln that lies between the calcining zone and the burning (or) the clinkering zone of the kiln. Temperature of this zone varies from 1200℃ to 1400℃. This is a critical zone of the kiln since liquid formation starts here causing high level of chemical attack on refractory. Very often second tuyere of the kiln is located in this area causing additional mechanical …

  • lime recovery kiln| refractory products - resco products

    The burning zone is the hottest location in a lime recovery kiln. Here dissociation of calcium carbonate occurs at high temperatures, producing the lime product. Depending on the process, the burning temperature can vary from below 2000°F (1100°C) to nearly 2500°F (1370°C), and this will dictate refractory selection for the burning zone

  • rotary lime kiln| select refractory products | resco products

    Rotary lime kilns typically have four refractory zones with varying types of refractory. Long process kilns require abrasion resistant, high strength alumina brick for the charging zone. The charging zone is where the abrasion of the stone can be particularly severe. Short preheater kilns normally do not have a charging zone that sees high abrasion as the preheated stone is partially softened
