|Title:||TO STUDY THE PERFORMANCE CHARACTERISTICS OF WET SCRUBBERS FOR BAGASSE FIRED BOILER|
|Keywords:||CHEMICAL ENGINEERING;WET SCRUBBERS;BAGASSE FIRED BOILER;AIR POLLUTION|
|Abstract:||In countries producing sugar from sugarcane, Bagasse, a by-product of milling cane is a captive fuel for the boilers of the sugar factories. Most of these boilers are with capacities ranging from 5-50 TPH of steam. Generally these boilers employ Step Grate/ Horse Shoe/ Spreader Stoker type of furnaces either with Natural/ Induced or Balanced Draft. These boilers are not efficiently designed (efficiency 60-65%) and are thus one of the most serious contributing source of AIR POLLUTION as far as particulate matter is concerned. The SO2 and NOx emissions from BAGASSE FIRED BOILERS are quite low and well within the norms of the Pollution Control Boards. In the present work, the characteristic properties of the bagasse affecting the particulate emissions - have been investigated. A comprehensive study of various types of boilers and furnaces used for the combustion of the bagasse has also been made. The available particulate control equipments and their suitability for the bagasse fired boilers is then discussed. After making a comparative assessment of all the available technologies, on the basis of the available data, it was decided to study the performance characteristics of the U-Bend Cyclone . Scrubber, as this appears to be one of the best available dedusting equipment for bagasse fired boilers that can meet the standards set by the Pollution Control Board. An account of the various parameters affecting the design and performance characteristics of this scrubber is also presented. Finally, all the available DEDUSTING EQUIPMENTS for bagasse fired boilers are compared on the basis of the performance studies and the literature available.|
