小型卧式快装锅炉燃煤改成燃油时,主要是改造燃烧装置和炉膛部分。1 燃烧器的选用和布置燃烧器是由油嘴(雾化器)和调风装置两部分构成。目前,大多数燃油锅炉采用机械雾化方式,其中压力雾化式最为常见,少数用转杯雾化式。压力雾化式主要利用高压油通过切向槽和旋流室经喷孔喷出,雾化角70°~120°,其燃烧特性是火炬形状可随负荷变化,火焰短粗,适用于小型快装锅炉及
Small horizontal fast boiler into coal-fired fuel, mainly to transform the combustion device and the furnace part. 1 burner selection and layout Burner is the nozzle (atomizer) and the wind device is composed of two parts. At present, most oil-fired boilers use mechanical atomization method, of which pressure atomization is the most common, a few with rotor cup atomization. The pressure atomization type mainly uses high-pressure oil through the tangential grooves and swirl chamber through the spray holes, the atomization angle of 70 ° ~ 120 °, the combustion characteristics of the torch shape can vary with load, short stubby flame, suitable for small fast Boiler and installed
