1. Arrangement of Burners for Oil-fired Boilers
目前，快装式燃油锅炉要求炉子体积小，热负荷高。 主要措施有两点：是提高燃烧器的雾化质量，第二是提高燃烧器出口的风速，使内部气流更加混合。 强大。 气流的横截面减小并且燃烧很强，因此燃烧器的布置与炉子的热负荷密切相关。 小型燃油锅炉都是单燃烧器，根据烟气冲程的方向排列在立式锅炉的顶部或底部。 通常，卧式快速安装的火管锅炉配备有1?2个燃烧器，并水平放置。
At present, fast-loading oil-fired boilers require small furnace volume and high heat load. There are two main measures: the first is to improve the atomization quality of the burner, and the second is to increase the air speed at the burner outlet to make the internal air flow more mixed. Powerful. The cross section of the air flow decreases and the combustion is very strong, so the arrangement of the burner is closely related to the heat load of the furnace. Small oil-fired boilers are single burners, arranged at the top or bottom of vertical boilers according to the direction of flue gas stroke. Usually, the horizontal fast-installed fire tube boilers are equipped with 1 or 2 burners and are placed horizontally.
将水管锅炉或燃煤锅炉改为燃油锅炉。 燃烧器中心与侧壁的距离应不小于1?1.2m，下部燃烧器至炉底的距离应不小于1m； 如果使用两个燃烧器，则中心之间的距离也应保持约1m，并且两个燃烧器的转向应相反。 当单个燃烧器的油耗为500?1000kg / h时，炉深不少于4m； 燃油消耗当温度为200?500kg / h时，炉深不小于3m。
Change water-pipe or coal-fired boilers into oil-fired boilers. The distance between the center and the side wall of the burner should be no less than 1 1.2 m, and the distance between the lower burner and the bottom of the furnace should be no less than 1 m. If two burners are used, the distance between the center should be kept about 1 m, and the steering of the two burners should be opposite. When the oil consumption of a single burner is 500-1000KG / h, the furnace depth shall not be less than 4m; when the oil consumption is 200-500kg / h, the furnace depth shall not be less than 3m.
2. Arrangement of Gas-fired Boiler Burners
锅炉炉的大小和形状与燃料特性密切相关。 燃气锅炉的燃烧过程比燃料简单，燃烧所需的时间较短，所需的炉膛体积较小。 燃烧器的布置应与炉子的形状结合起来考虑。 火焰已满，火焰未被水冷壁冲洗。 燃气锅炉通常装有燃烧器，系统简单，操作管理方便，节省投资。 对于大容量的燃气锅炉，可以布置两个燃烧器。 通常，采用上下布置，即使减轻负载，停用一个燃烧器也不会导致火焰偏离炉膛中心，从而影响水循环的可靠性和过热器的温度偏差。
The size and shape of the boiler are closely related to the fuel characteristics. The combustion process of gas fired boilers is simpler than that of fuels. The combustion time is shorter and the furnace volume is smaller. The arrangement of burners should be considered in conjunction with the shape of the furnace. The flame was full and the flame was not washed by the water wall. Gas-fired boilers are usually equipped with burners. The system is simple, easy to operate and manage, and saves investment. For large capacity gas-fired boilers, two burners can be arranged. Usually, if the upper and lower arrangement is adopted, even if the load is reduced, the shutdown of a burner will not cause the flame to deviate from the center of the furnace, thus affecting the reliability of the water cycle and the temperature deviation of the superheater.
由于结构上的限制，壳式锅炉以对称的水平排列的双炉布置。 每个燃烧器都配有一个燃烧器。 燃气锅炉燃烧器可以安装在锅炉的前壁和底部。 如果烟气出口在炉子的底部，则可以将燃烧器放在炉子的顶部。
Due to structural constraints, shell boilers are arranged in a symmetrical horizontal arrangement with two furnaces. Each burner is equipped with a burner. Gas-fired boiler burners can be installed 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 placed at the top of the furnace.
