Burning unit enhancement using multiple heat exchanger configurations

الملخص EN

Incineration is a thermal treatment process which mainly used to treat the waste material and convert it to ashes, flus gases and thermal energy.

This technique has a positive impact on the environment as it successfully addresses the dangerous waste materials.

Incorporating a heat exchanger with the incinerator was proved to have a high positive impact on the overall performance.

Numerical and/or experimental investigation of incorporating heat exchanger with incinerator could be used to study the system performance.

The commercial software, Ansys 2020, was used in the current workto analyze the various parameter of the heat exchanger such as heat transfer, pressure drop, quantity of heat, velocity, and temperature.

The present paper mainly focusses on the temperature distribution and the efficiency of the heat exchanger and improving the exhaust gases' conditions in the incineration.

The current work shows the validity of the outlet cooling water to be used as a source of heat.

The proposed design shows an excellent cooling for the exhaust gases compared to that of current design.

The results of the current work show that the outlet temperature of the cooling water for the proposed heat exchanger is dramatically higher than that of the current heat exchanger.

For instance, at the flow rate of 0.4 kg/s, the outlet cooling water temperatures were found to be 70 ºC and 30 ºC, for the proposed and the old heat exchanger, respectively.
