Evaluation of the combustion system, in a laboratory scale, for the energy use of the solid from activated sludge treatments of urban wastewater

Abstract

The combustion of solid fuel has a complexity different to the liquid and gaseous fuels. It is of interest to know the possibilities of recovery of numerous urban solid waste and the different configurations which affect to the combustion process. In order to take an advantage of the energy use of the urban solid waste from activated sludge waste water plants in particular, a pilot system has been implemented in a laboratory scale, to evaluate the main variables affecting to the combustion. The objective of this article is to show the experiences and to define these variables which affect to the correct combustion for a better evaluation of the solid from activated sludge treatments of urban wastewater.
