THERMAL ENERGY EVALUATION OF THE INCINERATOR MEDICAL WASTE

Abstract

The global warming problem and the rising cost of energy has raised the interest in the application of alternative energy for the energy system to increase efficiency and to reduce the emission of pollution. However, the key challenge of the energy systems was to find an appropriate way to decrease energy loss and increase the efficiency of energy transfer. This research aimed to evaluate the thermal energy obtained and heat loss from the incinerator waste installed in Suphan Buri Province, Thailand. The incinerator system composed of 6 sections: the first section was a waste hopper and feeder, the second section was the rotary kiln primary, the third section was a secondary chamber, the fourth section was the ash cooling conveyer, the fifth section was cyclone and the sixth section was a stack. This study applied 200 kilograms of waste and 200 liters of diesel oils as raw materials for the incineration process. The results showed that the total flow rate from overall input materials was 875 kilograms per hour and the total heat rate from overall inputs was 3,503,032.25° Kelvin. In terms of heat losses, total heat losses from the surface were 2,789,424.75 ° Kelvin while overall heat losses were 3,503,032.25 ° Kelvin. The results showed high thermal efficiency and suitable for application in the engineering process.
