本文阐述了“上海”号主锅炉的燃烧调整与测试,给出了燃烧的调整方法与测试数据。试验证明,由于采用了较合理的风油配比及适当的燃油预热温度,改善了燃烧,因此可节约燃油3％,另外,从燃烧理论上分析了恶化燃烧的机理,并针对目前的倾向,全面地讨论了燃油预热温度过低的弊病,指出所选择的预热温度必须确保在此温度下的恩氏粘度为3～5°E,才能满足完全燃烧。最后提出了改善燃烧、防止冒黑烟、节约燃油的重要措施如下: (1)选择适当的燃油预热温度,渣油一般在120～140℃之间; (2)提高预热空气温度,一般在125℃以上; (3)保持雾化片最佳技术状态; (4)合理调整调风机构的风门角度和扩散器的位置; (5)调整合理的风压。
This paper describes the “Shanghai” main boiler combustion adjustment and testing, given the combustion adjustment methods and test data. Experiments show that due to the use of a reasonable ratio of oil to oil and the appropriate temperature of the fuel preheat, improve combustion, it can save 3% of fuel, In addition, from the combustion theory to analyze the mechanism of deterioration of combustion, and for the current tendency , Comprehensively discussed the shortcomings of the fuel preheating temperature is too low, pointed out that the selected preheating temperature must ensure that the temperature at this temperature Engler viscosity of 3 ~ 5 ° E, in order to meet the complete combustion. Lastly, some important measures to improve combustion, prevent black smoke and save fuel are as follows: (1) Select proper fuel preheating temperature, residual oil is generally between 120 and 140 ℃; (2) to increase preheating air temperature, generally At 125 ℃ above; (3) to maintain the best technical state of the atomizer; (4) reasonable adjustment of the wind institutions throttle angle and diffuser position; (5) adjust the reasonable wind pressure.
