- Abstract:
- Thermal efficiency,as an important indicator to measure the heating furnace advanced and the op-eration, is directly related to a level of energy consumption of the workshop production.Based on a combustionstatus of the wax oil hydrogenation unit heating furnace for Luoyang petrochemical company,some factors ofinfluence on the thermal efficiency of heating furnace were analyzed,and some improvement measures wereput forward to achieve the goal of energy saving. Furnace thermal efficieney is mainly affected by the excess airratio,exhaust gas temperature,carbon monoxide content of factors. the results show that the excess air coeff-cient increased about 6.3%, thermal efficiency reduced about 0.4% when the oxygen content is increased by1 % ; amount of carbon monoxide is increased by 100 mg/L,thermal efficiency is reduced by about 0.05% ;and the exhaust gas temperature is increased by 5 ℃,the thermal efficiency of about 0.25% is lower. In or-der to improve the efficiency of the heating furnace,it is necessary that oxygen content is with in 2% ~4%, exhaust temperature is with in 125 ~ 135 ℃ and as low as possible for the content of carbon monoxide.
