南京炼油厂HG-120/39-11燃油锅炉原采用机械雾化。旋流式调风器,炉膛出口最大含氧达3.8％。过剩空气系数α=1.19,影响炉效及尾部受热面的运行周期。 1990年我厂与西安热工所合作采用了平流式调风器,油枪分蒸汽雾化和机械雾化两种,接头采用高压波形管活络接头。油嘴采用改良“Y型蒸汽雾化油嘴”。其特点,利用高速蒸汽作动力使重油雾化,由于油孔、气孔、混合孔呈直角相交内混状,蒸汽从油枪中间进入,与通过套环形空间来的油相碰撞而雾化,雾化了的燃料油由喷孔喷出,喷孔直径dp=3mm,共
Nanjing Refinery HG-120 / 39-11 oil-fired boiler used mechanical atomization. Swirl flow regulator, the maximum furnace outlet oxygen content of 3.8%. Excess air coefficient α = 1.19, affecting the furnace efficiency and the heating surface of the tail cycle. In 1990, our factory cooperated with Xi’an Thermotechnics Co., Ltd. Adopting the advection type air conditioner, the oil gun was divided into steam atomization and mechanical atomization, and the joint was made of high-pressure corrugated pipe active joint. Oil nozzle with improved “Y-type steam atomizer nozzle.” Its characteristics, the use of high-speed steam as the motive power of heavy oil atomization, due to oil holes, pores, mixing holes at right angles intersect within the mixing, steam from the middle into the oil gun, and through the annular space to the oil collision and atomization, atomization The fuel oil from the jet hole, jet diameter dp = 3mm, a total of
