Design of Combustion Air Inlet
Following Tran and White (1992), the burning rate, , of a typical fuel wood based on mass loss rate is between 2.92 gm-2s-1 and 9.80 gm-2s-1. "m&
Assuming up to six layers of wood pieces each having a rectangular cross-section of dimensions 15 x 15 mm, the actual surface area of the wood pieces exposed to burning may be approximated to fourteen times the cross-sectional area of the combustion chamber.
The mass of wood burned per second may then be expressed as,
amm"14&&=. (1)
Based on the maximum burning rate of the fuel wood then, 48.9142dmƒÎ~~=&= 3.4913 gs-1.
