Sugar application in Tamil Nadu

Introduction:

Wereceived an order to design and install a bag filter to capture dust from flue gases generated from burning spent wash in the boiler from a sugar distillery client based out of Tamil Nadu. The fuels used in the boiler here are spent wash & bagasse. Clair designed and installed the bag filter to achieve an outlet emission of ≤ 30 mg/Nm³.

Observations:

• The bag filter designed can accommodate gas flows from 19 to 22 m³/sec
• The bag filter can handle inlet dust load capacity from 6 to 38 gm/Nm³
• The flue gas composition varies radically and CEPL’s bag filters are designed to handle these variations comfortably
• The guaranteed differential pressure across the bag filter is 180 mm WC
• Currently the bag filters are operated between 120-140 mm WC and have been able to save on the motor power KW
• The plant is able to generate 2.2 MW power from the incineration process which has enabled the plant to be self-sufficient with regards to power consumption
• The steam generated by the plant is also being used for steam requirement of the distillery plant
