The Efficiency Of Evaluation And Research On Energy Saving Technology Of Tubular-furnace

Furnace plays an important role in the refinery production, as a direct combustion fuel and heating process media equipment. Jinzhou Petrochemical Company in use, with the main heater 25, but has never been a scientific and rational, uniform thermal efficiency test method, Over time, causing excessive fuel consumption, increased production costs also increased greenhouse gas emissions. In order to rationally and effectively measure and calculate the thermal efficiency of furnace, so that calculation has been optimized to avoid the complicated calculation process, to achieve thermal efficiency calculation intelligent, easy management and use of the furnace, and then test and calculated data to guide real-time energy saving , This greenhouse gas emissions with the current environment, analyze the characteristics of Jinzhou Petrochemical Company furnace and carried out evaluation and energy saving heating efficiency study's,the main results are as follows:On SHF0001-99 and GB2588-81 involved in the thermal efficiency calculation method of analysis, clearly a different method from the relationship between efficiency, so that the measured thermal efficiency furnace comparable, thus facilitating the tube furnace thermal efficiency of the calibration, assessment and management. Analysis of the British KANE company KM940 integrated gas analyzer test calculation method, compared with our standards, and on this basis, the completion of the instrument adjustments, the instrument is more suitable for China's national conditions, test results reflect more realistically the furnace of actual energy utilization. Improve all kinds of parameters (material parameters, thermal parameters, etc.) of the algorithm, reducing the Chattooga brought the artificial error, making the results more accurate calculation of thermal efficiency for the realization of the foundation program. Completed the main furnace thermal efficiency of all devices tested, the furnace is running in the operation provides a reliable basis for adjustment.Through experiments and analysis of research, the following was obtained: the efficiency of research and development of the furnace a counter-balance calculation program in this issuse is applications and expansion for SHF001-99 and GB2588-81 standard; SH estimation method can be used as SHF anti-balance method to obtain the thermal efficiency of the simple algorithm, in the daily management quickly and accurately complete the thermal efficiency estimates for the adjustment and assessment of tubular-furnace operating conditions; Furnace during operation to monitor the oxygen content in flue gas, and this amount of combustion air under control while ensuring complete combustion of fuel under the premise of reducing the excess air volume - this is in the production process to improve the thermal efficiency of most furnaces The easiest way the economy; After transformation, the exhaust gas temperature lower than the transformation of the former 20℃, Flame full degree greatly improved fuel burn rate of nearly 7%, has brought considerable economic benefits.
