Forced primary and forced secondary air biomass internal combustion top-lid updraft cook stove

Abstract

The invention is a novel Top-Lit-Updraft cook stove with internal forced primary and secondary air, designed to burn biomass. The cook stove is specifically designed to cleanly burn biomass. The stoves design innovations include a cylinder-within-cylinder design to provide heated, forced secondary to the burner area right below the burner. The burner design addresses limitations in previous cookstove burner design by implementing a bluff body design to direct syngas to the secondary air jets, improving mixing and combustion of volatile gases.

What is claimed: 
     
         1 . A forced primary and forced secondary air Top-Lit updraft internal combustion biomass cook stove. 
     
     
         2 . A cylinder-within-cylinder stove design to allow for one air source supplying both primary and secondary air by pressurizing a contained volume. 
     
     
         3 . A bluff body burner to facilitate mixing of syngas and secondary air. 
     
     
         4 . A design to facilitate internal secondary air and syngas mixing and combustion.
