Reform Practice of Waste Heat Utilization Device for Catalyst Roasting Furnace
Firstly,the current situation and existing problems of waste heat recovery and utilization in catalyst calcination furnaces were intro-duced.By opening a waste heat suction port at the lower part of the cooling unit,a square tube was introduced into the heating unit.After the ren-ovation,the product's furnace temperature was reduced by50℃from80℃,the furnace chamber temperature of the cooling unit was reduced from 220～240℃to120～150℃,and the temperature of the waste heat insulation pipe was increased from90～120℃before the technical renovation to 180～220℃.The energy consumption per ton of catalyst product was reduced by 50 kW·h,saving energy of 15000 kW·h annually.After the technical transformation,the maintenance of the waste heat relationship in the catalyst calciner has become more convenient,the insulation performance of the waste heat pipe has been greatly improved,and the efficiency of waste heat utilization has been effectively improved.
