主要针对油田注汽锅炉的热损失进行了分析,即(1)排烟热损失;(2)化学不完全燃烧热损失;(3)散热损失。并在此基础上提出了提高热效率的措施:(1)降低锅炉排烟温度;(2)保证锅炉能够充分完全燃烧,调整锅炉过量空气系数在1.05～1.2之间;(3)保温绝热层隔热性能要良好,同时加强辐射段内炉管的吸热能力;(4)提高锅炉进水温度。 Mainly for the oil field steam injection boiler heat loss were analyzed, namely (1) exhaust heat loss; (2) chemical incomplete combustion heat loss; (3) heat loss. On this basis, measures to improve thermal efficiency are put forward: (1) to reduce boiler exhaust temperature; (2) to ensure full and complete combustion of boilers, and to adjust boiler excess air coefficient between 1.05 and 1.2; (3) Thermal performance should be good, while strengthening the heat absorption capacity of the furnace tube; (4) to improve the boiler inlet temperature.
