Optimization of a stairmand cyclone adapted with water sprayers

Sugarcane bagasse is a lignocellulosic material commonly used as fuel in the cogeneration process, which a general way, aims to supply the demands of thermal energy and electric power plant. As a consequence, the burning biomass generates gaseous pollutant and significant quantities of particulate material, whose the particle granulometry varies according to the sugarcane species, the type of preparation, the type of milling and combustion. However, considering that these particulate materials when suspended in the atmosphere are environment harmful and noxious to human health, since the smaller the particle size, the greater its capacity to penetrate the respiratory duct, there are specific government laws that regulate their emissions. Thus, an alternative to the emission control of gaseous effluent will be given through the equipment installation at the boiler outflow, which the most used are: the cyclones, the bag filters, the electrostatic precipitators, and the scrubbers.
In view of the options available, the most appropriate equipment is based on the study of feasibility economic, technical, efficiency, and framework to the demands of the current legislation. Among the mentioned equipment, cyclones are the most simple, low cost of installation and maintenance...

Therefore, the aim of this study is to obtain the maximum collection efficiency of respirable particulates present in the gaseous outflow from a cyclone adapted with water sprayers on the sides of the equipment...
