标题：ANALYSIS OF THE INFLUENCE OF HEATING FURNACEINLET TEMPERATURE ON HEATING EFFICIENCY BASEDON THE PRINCIPLE OF OILFIELD ENVIRONMENTAL ANDECONOMICAL PROCESSING
摘要：The heating furnace is one of the important components in the surface engineering of o il and gas gathering and transportation. Its heating efficiency directly affects the final economic benefits of the entire process and the decreasing of environmental pollution. I f the inlet temperature of the heating fUrnace is different, it w ill lead to differences in the temperature of the w all surface, the heat radiation loss, and the smoke exhaust loss of the heating fUrnace, which w ill directly affect the heating e fficiency of the heating furnace. Regarding the effect of the inlet temperature of the heating furnace on the heating efficiency, we use the FLUENT software to construct a model of a naturally ventilated coil heating furnace. Combined w ith the relevant heating efficiency calculation formulas, the heat loss, exhaust smoke loss and anti-equilibrium heat effect of different inlet temperatures are simulated separately. We set the relevant parameters of the heating furnace according to the on-site working conditions. The research shows that when the inlet temperature of the heating furnace is between 1 050 °C-1 250 °C, the heating furnace is in a normal working state, and its thermal efficiency is higher than 90%. When the inlet temperature of the heating furnace is 1 150 °C, the heating furnace can reach the best state, and its thermal efficiency can reach 90.23%. When the inlet temperature of the heating furnace is less than 1 050 °C or higher than 1 250 °C, the heating furnace is in an under-load and over-load state, and its thermal efficiency w ill be less than 90%. In order to improve the efficiency of the heating furnace, no matter what kind of heating furnace, the inlet temperature should not be excessively increased. The optimal inlet temperature should be determined through simulation or experiment to ensure that the heating furnace is in the state of optimal heating efficiency.
