影响锅炉炉膛燃烧的因素很多,如:风量、喷油压力、油温、喷油嘴孔径等。经分析,其中起主要作用的是喷油嘴孔径的大小。所以将喷油燃烧的其它条件固定在原情况下,改变喷嘴孔径进行优选。去年我厂改燃煤为燃油后,用的是孔径1.2毫米的喷嘴,结果火焰不能充满炉膛, Affect the combustion of the boiler hearth many factors, such as: air volume, injection pressure, oil temperature, nozzle diameter and so on. After analysis, which plays a major role is the size of the nozzle aperture. Therefore, the fuel injection and combustion of other conditions fixed in the original case, to change the nozzle aperture is preferred. Last year, I plant to change the fuel for the coal, the aperture is 1.2 mm nozzle, the result of the flame can not be filled with the hearth,
