the lime kilm plant converts calcium carbonate to calcium oxide lime reburning is part of the chemical circuit called lime cycle lime is a recirculating auxiliary chemical used to convert green liquor coming from the recovery boiler to white liquor this is accomplished in the recosticizing plant， the recosticizing equipment and the lime reburning equipment together form the lime cycle the processes in the lime kiln plant happens as follows it starts with lime mud dry washed and mechanically dewatered lime mud is fed from the lime mud filter by a conveyor into the screw feeder and further into the lime mud dryer of the lime kiln the lime mud dryer is a vertical duck starting directly from the lime kiln feed end and is tangentially connected to the cyclone lime mud is fed into the flu gas flow it is carried with the flu gas to the cyclone and flash dry to about one hundred percent dryness the cyclone separates the dry lime mud from the flu gas then flue gas enters to the flu gas handling system glue gases from the line kiln contain variable amounts of dust normally five to fifteen percent of the kiln production the lime dust is separated from the flu gas in the electrostatic precipitator and returns to the lime kiln an id fan transfers flu gases from the kiln through the flu gas duck to the electrostatic precipitator and further to the stack the dry lime mud from the cyclone proceeds to the lime reburning process the main equipment in the lime reburning is the lime kiln it is a horizontal cylindrical brick lined steel drum installed on a slight slow so that the lime is conveyed from the feet end to the firing end as the kiln rotates lime regeneration is called reburning because the reaction requires a relatively high temperature and thus needs a lot of heat in the kiln dissociation of lime mud to calcium oxide and carbon dioxide commences at a temperature over eight hundred fifty degrees celsius， the reaction is greatly accelerated when the temperature rises to obtain proper reaction speed reburning is carried out at approximately eleven hundred degrees celsius the objective of the lime reburning is to obtain homogeneous and porous lime with low residual carbonate， which will slake easily and the resulted lime mud can be easily separated from the white liquor， a steady and trouble free kilm operation is a vital precondition for successful burning in the lime kilm， the retention time is three to five hours during which lime mud is preheated and lime particles are formed slow heating towards the burning temperature and the right burning temperature result in a homogenous product next the line goes through the lime handling process the lime leaving the kiln contains a significant amount of heat the heat is required covered in a sector cooler the lime cool is used to transfer heat from the product to the secondary combustion air entering the kiln the lime cool is installed around the kiln shell over the burning zone and rotates with the kiln from the sector cooler the fine lime falls through the diverter gate directly to the burnt lime conveyor bigger lime particles dropped to another diverter gate and then via crusher onto the burnt lime conveyor from the conveyor the lime falls onto the burnt lime elevator which will lift it further into the burnt lime bin to make all this possible it is necessary to have a burning system a burner is located at the firing end of the lime kiln and provides the heat for calcining the lime mud there are various different fuels which can be used for burning the burning system consists of burners for selected fuels fuel handling， ignition gas， handling compressed air and steam handling as well as blame control and safety systems。

the recosticizing plant is designed to produce strong and clean white liquor containing a minimum amount of unreactive chemicals for the cooking process green liquor which is produced as a byproduct of burning black liquor and burnt lime from the line kiln are used as raw materials the processes in a recosticizing plant are the following it starts with green liquor handling the basic purpose of the green liquor handling is to filter green liquor coming from the recovery boiler dissolving tank so it can be suitable for recosticizing green liquor is pumped from the recovery boiler dissolving tank to a raw green liquor tank the purpose of the raw green liquor tank is to stabilize the concentration temperature and flow fluctuations in incoming green liquor the raw green liquor tank also acts as a storage tank between the recovery boiler and the green liquor filter the line green filter is a pressurized filter which separates drags from the raw green liquor by cross flow filtration the pressure difference across the filtering surface horses part of the liquid through the element a circulation pump sends the green liquor to the top of the filtering elements and the large downflow prevents the drags from forming a cake the capacity of the line green filter is controlled by the pressure difference across the filtering surface clean filtrated green liquor is sent to the green liquor tank concentrated drags are discharged periodically from the filter green liquor temperature must be reduced in most mills prior to the recosticized this is done in the green liquor cooler， which is a combination of an expansion vessel and a heat exchanger both operating under slight vacuum， the next process and the recosticizing plant is green liquor drags handling which means drags washing de watering and removal from the process this happens in the lime free drags centrifuges the purpose of the green liquor drags washing and drawing is to replace the liquor in the dreg's suspension with alkali free liquid water， the original liquor which is slightly diluted returns to the process the washed drags are discharged as dry waste from the process， the following processes in the recosticizing plant are lime slaking and costicizing green liquor and lime are mixed together in a predetermined proportion in the slaker classifier， the first reaction is lime slaking and it takes place in the lime slake， the costicizing reaction starts immediately after slaking grits， which may remain from lime are removed as waste from the process in the classifier， the rest of the costicizing reaction takes place in the costicizer text， the costicizing line consists of three costicizers connected in series， their purpose is to give lime milt sufficient retention time to complete the reaction to obtain white liquor filtration then white liquor and lime mud resulting from the recosticizing reactions follow to the white liquor filtration they are separated from each other in the lime white filter the most important goal of separation is to produce clear white liquor without any residual lime mud the white liquor separation is based on pressurized disc filtration filtrated white liquor is pumped from the lime white filter to the white liquor storage tank lime mud is pumped to the lime mud storage tank the final process in the recosticizing plant is the lime mud filtration lime mud from the lime mud storage tank is pumped into a vacuum type disc filter the purpose of the lime dry filter is to wash alkali away from lime mud and raise dry solids content to a suitable level before it is fed into the lime kiln the quantity in the density of the lime mud pumped into the lime dry filter are precisely controlled as these values determine the lime kiln production alkaline liquids in filtrates produced in the process are called weak wash they are collected and stored in the weak washed storage tank and from there pumped to the recovery boiler dissolving tank to control the green liquor density。
