    • A retractable sootblower (100), having a movable carriage and lance tube assembly (110, 115) for cleaning inside surfaces of a boiler, includes a stationary starter switch (37) for initiating operation of the sootblower (100) and a cable (40) disposed between the movable assembly (110, 115) and the starter switch (37) for transmitting electrical current from the starter switch (37) to the moveable assembly (110, 115). A limit switch (130) is mounted to and moveable with the moveable assembly (110, 115). A stationary switch control device (140) is disposed proximate the boiler and configured to cooperate with the limit switch (130) so as to reverse the direction of movement of the moveable assembly (110, 115) during sootblower (100) operation by reversing the direction of the current to the moveable assembly (110, 115).
    • 一种具有用于清洁锅炉内表面的活动托架和喷枪管组件(110,115)的伸缩式吹灰器(100)包括用于启动吹灰器(100)和电缆(40)的操作的固定起动开关(37) )设置在可移动组件(110,115)和起动开关(37)之间,用于将电流从起动开关(37)传递到可移动组件(110,115)。 限位开关(130)安装到可移动组件(110,115)上并与可移动组件(110,115)一起移动。 固定式开关控制装置(140)设置在锅炉附近并且被配置成与限位开关(130)配合,以便在吹灰器(100)操作期间通过反转来反转可移动组件(110,115)的移动方向 电流到可移动组件(110,115)的方向。

    • A thermal gasification installation comprising a gasifier for producing a gas from a biofuel and a heat exchanger (11) having at least one heat transferring wall (21, 22) separating two heat exchanger sides (23, 24, 25) with opposite flow directions. The two heat exchanger sides (23, 24, 25) are during operation serving for the flowing through of a heated gas flow (x) from the gasifier and a cold airflow (y, z) from the airflow generator, respectively. The installation is arranged to periodically make the gas flow (x) and the airflow (y) change heat exchanger side (23, 24, 25) whereby the heating surfaces of the heat exchanger (11) is cleaned of encrustations. Thereby the thermal gasification installation will always be operating with an optimum good energy economy and produce a pure producer gas which is suitable as fuel for a gas engine. The gas is purified dryly without the disadvantages involved with a conventional liquid purification.
    • 一种热气化装置,包括用于从生物燃料生产气体的气化器和具有至少一个以相反流动方向分离两个热交换器侧面(23,24,25)的传热壁(21,22)的热交换器(11)。 两个热交换器侧面(23,24,25)分别在来自气化器的加热气流(x)和来自气流发生器的冷气流(y,z)中流动。 该安装被设置成周期性地使气体流(x)和气流(y)改变换热器侧(23,24,25),由此热交换器(11)的加热表面被清洁。 因此,热气化装置将始终以最佳的良好的能量经济运行并产生适合作为燃气发动机的燃料的纯生产气体。 气体被干净地纯化,而没有常规液体纯化所涉及的缺点。
