If you want to learn about our products , please call or write mail consultation.

Oct 29, 2014 · As the protecting layer is then damaged and its thickness reduced, hot spots are formed inside the shell, which results in loss of energy and disturbed kiln operation. To protect the steel shell from damage, its temperature should remain below 350 °C. This can of course easily be monitored with thermal imaging cameras

The “hot spot temperature” can be set individually for every nozzle. Cooling down a hot spot With the application of KILNCOOLER, a hot spot can be cooled down rap­idly but care­fully, a­void­ing any shrink­age of the kiln shell—cool­ing rate is up to 2 Kelvin per minute

advanced kiln shell temperature monitoring in cement plant

Prevent any interruption in cement plant due to hot spots Tasek cement plant in Malaysia aims to monitor the overall temperature of their 500 tpd rotary kiln no 3 to prevent any interruption in production due to hot spots. The cement plant shows a complex layout including many posts and pillars masking the shell

continuous kiln monitoring – cement americas

Feb 15, 2021 · This enhanced kiln shell scanning system enables cement manufacturers to avoid costly damage and unscheduled downtime by continuously monitoring rotary kilns to detect hot spots due to refractory loss, damage and wear. Using the CS210 infrared (IR) linescanning solution, which now supports up to four scanners, cement plant operators can

temperature control during clinker cooling process | visiontir

This hot air is used almost entirely as secondary air for combustion in the rotary kiln, or as tertiary air to the tertiary air duct. Clinker temperature control It is critical to monitor the temperature of the clinker searching for those hot spots in the material with a temperature above a set threshold before it reaches the conveyor causing

Tasek cement plant in Malaysia aims to monitor the overall temperature of their 500 tpd rotary kiln no 3 to prevent any interruption in production due to hot spots.The cement plant shows a complex layout including many posts and pillars masking the shell. A portion of the kiln is also located under a building. These obstructions prevent the IR scanner from seeing the entire kiln shell and

raytek® cs210 cement kiln process imaging system | fluke

Product Overview. The CS210 is an integrated kiln camera system that monitors rotary kilns to detect hot spots and avoid costly damage and unscheduled downtime. Optional, yet fully integrated, accessories extend the capabilities of this thermal imaging system to include shadow sensing, burning zone monitoring, tire slip, fan control, refractory

rotary kilns - williamson ir

If the refractory material lining the Rotary Kiln overheats or is damaged in any way, then hot spots appear on the kiln’s outer shell. Detecting these hot spots is crucial in maintaining the kiln’s structural integrity, protecting human health & safety, and preventing costly downtime

mechanical maintenance-of-cement-rotary-kiln

Jun 22, 2018 · Figure5: Hot spot and heat damage 2.7 HEAT DAMAGE Refractory-lined shells are prone to heat damage. When refractory fails, an area of the shell is superheated and a hotspot occurs. A hot spot is seen as a bright red or yellow area whose size can be as small as one brick or a much larger area

regular kiln maintenance & care guide | kiln frog

Sand any rough spots on the bottom or shelves and recoat with kiln wash. It is not necessary to kiln wash between each firing but a sufficient coating should be maintained. Power Up! Turn the power switch back on and make sure your kiln registers an appropriate room temperature for the inside of the kiln

keeping kiln shell temperatures under control

Jun 01, 2017 · The kiln shell temperatures nowadays seem to tend to vary faster and more unpredictable than this was the case several years ago. Beside hot spots and typical areas on the kiln shell where

kiln cooling using water based kilncooler - kima germany

Sep 06, 2017 · Control your kiln shell temperature with a water based kiln cooling system. Reliable and effective cooler for kiln shell. Due to the increasing usage of secondary fuels, which are relatively in-homogeneous, there are more fluctuations in the burning process. This leads to increased burden for the refractory and the kiln shell hot-spots may occur

kima sells five kilncooler - cemax

Sep 06, 2017 · The system monitors kiln shell temperature and cools only the specific spots that show temperatures above a setpoint. This helps to avoid a kiln shutdown and helps to prolong refractory life. Hotspots in the kiln are a growing problem for cement plants

temperature measurement for cement lime kilns

Temperature Measurement for Cement Lime Kilns. Most modern kilns have a 4 to 5 inch inside diameter by 4 to 5 foot long target tube in the sidewall of the kiln where monitoring mid-kiln temperature is critical to ensure kiln integrity. A PSC Non-Contact Infrared (IR) Pyrometer is recommended for measurement reading during each rotation of the

continuous surveillance of kiln shell temperature - cement

Continuous surveillance of kiln shell temperature. 1 Kilnscan allows thermal warp computation. 2 Thermal warp before the event. 3 Thermal warp during the event. 4 Thermal warp after the event. The maxim “health is wealth” is applicable to the cement kiln, too. As long as the shell is rotating, the level of profitability is high

thermo-elastic behavior study of rotary kilns for cement

Dec 01, 2020 · The kiln rotation in red spots presence can permanently damage the metal structure. The main purpose of this research is to find out distortions due to the ovality phenomena using a numerical method (finite element stresses analysis) by Patran/Nastran softwares and to compare the results with measurements obtained in Moroccan cement plant [2]
