THERMAL IMAGE TECHNIQUE AND THERMAL EFFICIENCY COMPARISON OF FIRED OVEN CHICKEN

Abstract

This research aims to investigate comparing the thermal efficiency of fired oven chicken consists of the fired oven chicken without insulation, insulation and the earthen jar to modify for the oven. The temperature results were confirmed by thermal image. The oven diameter of 50 cm. and height of 100 cm. Eucalyptus charcoal was used as a fuel for heating. The chicken weight about 1 kilogram and baking of 5 chickens per time. The results showed that the maximum thermal efficiency occurs as fire oven with insulate was 0.365. The baking time was 34 minutes, 300 grams of eucalyptus charcoal at the temperature of 280 ^oC. The thermal image was demonstrated the surface temperature of fire oven with insulate lower than fire oven without insulate and earthen jar to modified when the thermal diffuse around both oven with high temperature conduce to high heat loss, long period of time and high energy consumption.
