    • A nozzle for a circulating fluidized bed (CFB) boiler of the present disclosure relates to the field of mechanical engineering. The nozzle creates resistance to ingress of fine solid particles and maintains uniform air distribution therethrough. The nozzle has a body having a predetermined thickness and at least one passage configured along the thickness of the body such that, the passage extends from an inner surface of the body and terminates at an outer surface of the body. The passage facilitates the flow of a fluid from a lumen formed within the body to the outer surface of the body and vice versa. The passage has at least one bend. The bend restricts the backflow of fine solid particles through the nozzle to avoid the disturbance to the air flow pattern by the fine solid particles within the windbox.
    • 用于本公开的循环流化床(CFB)锅炉的喷嘴涉及机械工程领域。 喷嘴可以阻止细小固体颗粒的进入并保持均匀的空气分布。 该喷嘴具有一个具有预定厚度的主体和至少一个沿着主体的厚度构造的通道,使得该通道从主体的内表面延伸并终止于主体的外表面。 该通道有助于流体从形成在身体内的内腔流到身体的外表面,反之亦然。 该通道至少有一个弯曲。 弯头限制细小固体颗粒通过喷嘴的回流,以避免风箱内细小固体颗粒干扰气流模式。

    • Die Erfindung betrifft eine Wirbelschichtfeuerung (1) mit einem ersten stationären Wirbelbett (6), welchem zu verfeuernde Brennstoffe zufuhrbar sind. Dem ersten Wirbelbett (6) ist ein zweites stationäres Wirbelbett (6') mit Tauchheizflächen zugeordnet. Ein Wärmeaustrag aus dem ersten Wirbelbett (6) wird dadurch erhalten, indem überschüssiges Bettmaterial (10) selbsttätig vom ersten Wirbelbett (6) auf das zweite Wirbelbett (6') geführt ist. Gekühltes Bettmaterial (21) aus dem zweiten Wirbelbett (6') ist zu dem ersten Wirbelbett (6) rückführbar.
