    燃油燃气锅炉燃烧器的布置!

    1.燃油锅炉燃烧器的布置
    1. Arrangement of oil fired boiler burner
    目前生产的快装型燃油锅炉要求体积小,炉膛热负荷高,主要采取措施有两点:一是提高燃烧器雾化质量,二是提高燃烧器出口处的风速,使气流内部混合更强烈。气流的截面减小,燃烧就强烈,故燃烧器的布置与炉膛热负荷密切相关。小型燃油锅炉均为单个燃烧器,布置于立式锅炉炉顶或底部,视烟气行程方向而定,一般卧式快装火管锅炉均配置1~2个燃烧器,水平布置。
    At present, the fast loading oil fired boiler requires small volume and high furnace heat load. There are two main measures: one is to improve the atomization quality of the burner, and the other is to improve the wind speed at the outlet of the burner to make the internal mixing of air flow stronger. When the cross section of the gas flow decreases, the combustion is strong, so the arrangement of the burner is closely related to the furnace heat load. Small oil fired boilers are single burners, which are arranged at the top or bottom of vertical boilers, depending on the flue gas travel direction. Generally, horizontal quick fire tube boilers are equipped with 1 ~ 2 burners, which are arranged horizontally.

    对水管锅炉或燃煤锅炉改成燃油锅炉,燃烧器和侧墙的距离应不小于1~1.2m,下排燃烧器到炉底的距离不应小于1m;如选用两个燃烧器,则其之间的距离也应保持1m左右,且两个燃烧器旋转风的转向应相反,当单只燃烧器的耗油量为500~l000kg/h时,炉膛深度不小于4m;耗油量为200~500kg/h时,炉膛深度不小于3m。
    For water tube boiler or coal-fired boiler to oil-fired boiler, the distance between burner center and side wall shall not be less than 1 ~ 1.2m, and the distance from lower burner to furnace bottom shall not be less than 1m; If two burners are selected, the distance between their centers shall also be kept about 1m, and the rotation direction of the rotating air of the two burners shall be opposite. When the oil consumption of a single burner is 500 ~ l000kg / h, the furnace depth shall not be less than 4m; When the fuel consumption is 200 ~ 500kg / h, the furnace depth shall not be less than 3m.

    2. Layout of gas boiler burner
    锅炉炉膛大小和形状与燃料性质关系很大,燃气锅炉的燃烧过程比燃油简单,燃烧所需的时间较短,因而所需炉膛容积要小,燃烧器的布置应与炉膛形状结合起来考虑,以火焰充满度好,火焰冲刷不到水冷壁为原则,燃气锅炉一般布置一个燃烧器,这样系统简单,运行管理方便,投资省。对较大容量燃气锅炉,可以布置两个燃烧器。通常采用上下布置方式,即使负荷减小时,停用一个燃烧器,也不致造成火焰偏离炉膛,影响水循环的可靠性和过热器温度偏差。
    The size and shape of boiler furnace are closely related to the fuel properties. The combustion process of gas-fired boiler is simpler than that of fuel oil, and the combustion time is shorter, so the required furnace volume is smaller. The layout of burner shall be considered in combination with the furnace shape. On the principle of good flame fullness and flame brushing can not reach the water wall, gas-fired boiler is generally equipped with a burner, so the system is simple, Convenient operation and management and low investment. For large capacity gas-fired boilers, two burners can be arranged. It is usually arranged up and down. Even if one burner is stopped when the load is reduced, it will not cause the flame to deviate from the furnace center and affect the reliability of water circulation and the temperature deviation of superheater.
    锅壳式锅炉由于受结构的限制,均采用双炉胆对称水平布置,每个炉胆各布置一个燃烧器,燃气锅炉燃烧器可以布置在锅炉前墙、底部,若烟气出口处在炉膛底部,燃烧器可以布置在炉顶。
    Due to the limitation of structure, shell boilers are symmetrically and horizontally arranged with double furnace liners. Each furnace liner is equipped with a burner. The burner of gas-fired boiler can be arranged on the front wall and bottom of the boiler. If the flue gas outlet is at the bottom of the furnace, the burner can be arranged on the top of the furnace.
