Engineering Development of a Clean Burning Residential Wood Stove

摘要

Results are presented of a survey undertaken to assess the basic problems of residential wood stoves and the design approaches for the development of a clean wood-burning stove. It is determined that mean combustion temperatures approaching 1000C are needed, and that well-mixed, well-aerated flames are essential for low emissions. Also, controlled pyrolysis hot char-volatiles interaction, and controlled air flow are important considerations for clean burning of sticks and logs. The development of a mathematical and computational model of the residential wood stove based upon gasification, pyrolysis, combustion, fluid dynamic, and heat transfer processes in the stove is discussed. It is determined that a modular stove for laboratory testing and prototype design is feasible.
