Development of a system for burning different kinds of waste and scrap in a fluidized bed

Abstract

Incineration is one of the thermal processes that can be applied in the treatment of municipal solid waste to reduce the quantity and build energy. The heterogeneity of materials to try and emission levels imposed by the legislation has forced them to develop and/or adapt technologies specific to this process. One of these technologies is the use of fluidized bed. The fluidized bed teams are used to carry out processes of combustion of any fuel, these teams offer great advantages over conventional combustors. These advantages include; great flexibility for fuels, improvements in environmental design, easy to use energy generated and smaller. The aim of this study is to evaluate the operation of a fluidized bed, identifying variables greatest impact on the burning of a variety of waste and scrap, which were used for testing various fuels, including coke, wood, sawdust, ground rubber and oil automotive, during operation of the fluidized bed was determined the minimum speed of fluidization, the amount of sand to be used for good fluidization bed, quantity and air pressure required, the mass flow of optimum fuel fed, the temperature of ignition, bed, discharge of gases, as well as the concentration of the flue gas generated, including CO, CO2, O2 and H2O and efficient combustion process. Of the tests conducted were the parameters that have a greater influence on the operation and fluidized bed combustion process, which provides information for better operation of such equipment.
