摘要：Lo w grade, high ash and low calorific value of fuels can be effectively used in fluidized bed combustion; o therwise these lo w grade fuels are difficult to handle due to high moisture and fines content. In the present work the possibility of using Kutch lignite in the fluidized comb ustor to improve the combustion efficiencies are discussed. Increase in fluidized velocity along the vertical height above the distributor plate indicate that considerable burning of fuel particles is taking place in the freeboard zone rather than complete burning within the bed. Therefore, an enlarged disengagement section is provided to improve the combustion of fines. In the present work, a design of 50 TPH Coal based atmospheric fluidised bed comb ustion boiler in enlarge the free board zone.
