Flame shape and quality International Cement Review
CemNet » Magazine Articles » Flame shape and quality Flame shape and quality. By Arthur Harrisson In the cement manufacturing industry, people still tend to refer to the burner at the front-end of the kiln as the 'main' burner, even though in a precalciner some 60-70 per cent of the fuel may in fact be introduced to the feed before the rotary kiln is reached. Historically, we

Rotary Kiln Erratic Flame, Distorted Flame Shape
In continuation of our article 15 most common rotary kiln emergency conditions here we have discussed another rotary kiln problem and emergency situation which is related to burner flame. Sometimes the flame would go erratic or flame shows distorted shape. Such a situation could be dangerous especially, if allowed to prolong, as it may damage rotary kiln refractory lining, kiln shell, kiln
CEMENT AND LIME ROTARY KILN REFRACTORIES
Lining in the Cement & Lime kiln The current rotary kiln environment is becoming more chemically aggressive with the increasing use of secondary or waste fuels. The refractory bricks: › Must have good volume stability at the operating temperature and exhibit low permanent linear change and low expansion or shrinkage. › Must be cost effective. The objective of the
Rotary Kiln an overview | ScienceDirect Topics
Rotary kilns used in the cement industry are much larger in diameter and longer in length than the previously discussed incinerator. The manufacture of cement from limestone requires high kiln temperatures (1,400°C) and long residence times, creating an excellent opportunity for hazardous waste destruction. Further, the lime can neutralize the hydrogen chloride generated
How should the refractory brick of rotary kiln be
It is easy to burn out the nozzle, making it out of shape or broken, producing a disordered flame shape and damaging the kiln lining before it is replaced.If the volatile content of coal is too low and the ash content is too high (over 28%), the incomplete combustion of a large amount of pulverized coal will settle into the material for combustion and release a large amount of heat,

Cement kiln refractories
Cement kiln refractories. Refractories play a critical, if unseen, role in both the rotary kiln lining, and the lining of the high volume static equipment areas that comprise a modern pre-calciner kiln system. The durability of the rotary kiln brick lining generally determines the duration of a kiln operating campaign. Whilst great efforts are made to ensure appropriate refractory brick
