Fluidized Bed Combustion and Identification

The disposal of municipal solid waste (MWS) is a growing problem worldwide because of the increasing volume of the waste and the negative impact on the environment, health and safety. Among the combustion and incineration technologies, fluidized bed combustion is becoming more popular because of its ability to handle a variety of waste and advantages in controlling emission. However, in the high moisture content wastes with low calorific value, co-firing wastes with a supplementary fuel such as coal is being tried in many industrial and utility boilers. In order to ensure that these co-firing facilities are properly designed and operated, a fundamental understanding of the co-combustion phenomena including its dynamical characteristics must be established. It is for this reason a basic study on the co- combustion of MSW and lignite in a fluidized bed is proposed. The objectives of this book are to investigate the effect of main operating parameters on combustion characteristics, to quantify the fluctuating characteristics during steady-state operation using statistical analysis and to create a linear model obtained from input-output analysis.
