flue gas for coal dryer
Coal Dryer Kilburn
The exhaust gas from the dryer is passed through a bag filter for removing the fines carried over before releasing it to the atmosphere It is also possible to recirculate part of the flue gas from bag filter outlet to dryer This minimizes chances of explosion by reducing oxygen content in flue gasJun 30, 2007· With the fullscale coaldrying system operating at the target moisture reduction level, the flue gas flow rate to the spray towers will be reduced by about 4%, further lowering SO 2 emissionsLignite Drying: New CoalDrying Technology Promises Higher
Coal Drying Improves Performance and Reduces Emissions
The flow rate of flue gas leaving the furnace firing drier coal is lower compared to the wet fuel Also, the specific heat of the flue gas is lower due to the lower moisture content The result is reduced thermal energy of the flue gas Lower flue gas flow rate also results in lower rates of convective heat transferThe coal dryer works on the principle of agitated fluid bed coal drying The coal dryer removes the moisture from the unsized coal available at power stations as well as for process boilers The hot air required for coal dryer is generated from burning the coal fines dried in the coal dryer Superior Features Handles coal lumps of 40 to 200 mmCoal Dryer Manufacturer, India TTPL
