| Abstract | ||||
| In this study, energy and exergy analysis are studied to examine and understand the performance of the combustion chamber (furnace) of the heating unit in Nag Hammadi fiber board Company (NFB) with a capacity of 22 MW, utilizing natural gas and biofuel together where the combustion chamber is designed to burn natural gas and wood dust at the same time to decrease the operating cost of the heating unit. The main purpose of combustion chamber is to burn natural gas and biofuel to supply the heating unit by high temperature combustion products. There is no heat transfer inside the combustion chamber except heat losses through the wall of the combustion chamber. The purpose of the heating unit in the factory is to supply the manufacturing processes by hot flue gases for dryer unit, hot thermal oil for hot press system and saturated steam for the digester. The energy and exergy efficiencies are found to be 69 % and 28 %, respectively. This study is carried out to identify and quantify the energy and exergy losses in the combustion chamber. | ||||
