| Fish morphormetric parameters namely; length, thickness, width at several points and weight were determined as a prelude and were used to design the furnace-dryer for investigating the effects of hardwood-charcoal particle size on five of its combustion properties under natural convection. The tests were in a dryer at zero load. One-factor experiment at five levels of the charcoal sizes of 10, 20, 28, 37 and 50 mm were used to study four of the properties namely, burn-out time (BOT), burning rate (BR), peak temperature (PT) and the time it takes for the temperature to peak (TTP). For the fifth property which is temperature gradient (TG), a 5×14, two-factor experiment was used. The above charcoal particle sizes form one factor while time after igniting... |
