针对常规方箱式加热炉炉墙漏风 ,炉管易结焦及能耗大等问题 ,用QX系列热媒炉加热技术对胜利采油厂 6座集输泵站加热系统实施改造。热媒炉与方箱炉使用情况的对比分析表明 ,热媒炉平均热效率提高了 2 4 15% ,耗油量降低了 2 4 18%。热媒炉的温度和压力控制、检测、保护系统完善 ,运行安全 ,燃料燃烧完全 ,烟囱排烟量少 ,减少了对大气层的污染。针对热媒炉加热系统运行中出现的问题 ,建议 :( 1)燃烧器油泵压力应控制在 2 0～ 3 0MPa ,加热泵加热温度控制在 10 0～ 12 0℃ ,燃料油压力控制在 0 3～ 0 5MPa ;( 2 )热油循环泵额定参数应与实际生产参数相匹配 ,以避免循环泵功率过大造成无功损耗 ;( 3 )确保燃油质量 ,采取措施降低燃油的含砂量。
Aiming at the problems such as air leakage in furnace walls, easy coking and high energy consumption of furnace tubes, the heating system of 6 gathering pump stations in Shengli Oil Production Plant was retrofitted with QX series heat medium furnace heating technology. The comparative analysis of the utilization of the heat medium furnace and the square box furnace shows that the average thermal efficiency of the heat medium furnace is increased by 2 4 15% and the fuel consumption is reduced by 2 4 18%. Heat medium furnace temperature and pressure control, detection, protection system is perfect, safe operation, fuel combustion is complete, smokestacks less, reducing the pollution of the atmosphere. In view of the problems occurred in the operation of the heating medium heating system, it is suggested that: (1) the pressure of the burner oil pump should be controlled at 20 ~ 30MPa, the heating temperature of the heating pump controlled at 10 ~ 12 0 ℃, the fuel oil pressure controlled at 0 3 ~ 0 5MPa; (2) hot oil circulating pump rated parameters should be matched with the actual production parameters to avoid circulating pump power caused by reactive power loss; (3) to ensure fuel quality, to take measures to reduce the amount of oil sand.
