Calcined limestone kiln formed within the natural cycle

Kiln Products : calcined limestone kiln to form a natural internal circulation inside the kiln calcination of limestone to form a natural cycle , lime kiln enable natural circulation strengths and weaknesses in the calcination process , the use of lime kiln working fluid circulating their differences is a natural cycle , it consists of body composition loop heat pipes and water vapor is heated to produce steam , the pressure difference caused by the formation of water impetus kiln formed inside the water circulation loop . Using natural circulation has certain advantages: lime kiln can reduce operating costs , to a certain extent, reduce investment. Calcined to form a stable system, water capacity , good stability, low operating costs. Lime Kiln enable natural circulation , increasing the consumption of steel , and start and stop the process is slow, in the practical application of cement plants , power plants , using natural circulation occupy absolute market share. Lime kiln dust to clean inside and outside , the general vibration method . For high temperature heat transfer surface , dust different nature , sticky dust ones, in the low-temperature , vibration cleaning , laser cleaning method can quickly clean up projects in some lime calcining lime kiln on the use of membrane structure control, and high overall performance , the use of vibration cleaning , better, at high temperature , because the heat and the use of the suspension structure requires using a laser and steam cleaning . In addition, lime kiln dust , high temperature , the hopper is easy to form at high temperature ash , although the use of water-cooled ash bucket , but the greater the amount of ash , a waste of resources and more heat , automatic cleaning device is also the initial design failure, address this issue, in the early kiln smoke into the wind , adding a dust chamber , allowing the return of large particles of ash lime rotary kiln smoke chamber , much of this investment , but the effect is excellent , dust to clean up more than before 10% , high temperature ash has also been solved. Leading to the kiln flue gas from below into the body , after the kiln body circulation, from the upper discharge , which do not form water vapor and smoke reverse flow of wind , little effect on the heat , so the kiln into the outlet wear becomes particularly important. Kaolin kiln inlet pipe caused erosion under motivated wind lighter than the maximum operating conditions reach 13m / s, which because of the larger amount of dust , so the wear problem without delay. Studded tube kiln air duct replaced , upwind to avoid smearing wear castable . In the windward side of kaolin kiln were preventive treatment .
