Riassunto

Bridging the gap between theory and application, this reference demonstrates the operational mechanisms, modeling, and simulation of equipment for the combustion and gasification of solid fuels. Solid Fuels Combustion and Gasification: Modeling, Simulation, and Equipment Operation clearly illustrates procedures to improve and optimize the design of future units and the operation of existing industrial systems with recommendations and guidelines from a seasoned professional in the field.

Supplies an abundance of examples, models, and exercises for step-by-step instruction on the modeling and simulation of combustion and gasification machinery

Of critical importance to the industrial and design engineer, Solid Fuels Combustion and Gasification…

Clearly displays methods to build computer simulation programs that will effectively predict equipment performance

Offers methods to formulate sound mathematical models for boilers, gasifiers, furnaces, and incinerators

Shows how to interpret simulation results for the best design and operation of combustion and gasification equipment

Describes key aspects of solid and gas combustion phenomena

Provides detailed discussions of the basic and auxiliary equations used in specific projection models

Includes applications of moving and fluidized beds
