    • An improved support is disclosed for furnace shield tubes, which are located between the radiant and convection sections of industrial furnaces, and which, since they are exposed to radiant heat, are subject to significant weakening. In the preferred embodiment, a hollow pipe serves as a beam support for the shield tubes, the support being extensively insulated to minimize radiant heat input and being cooled by air passing inside it as induced by natural draft available from the furnace. Air from outside the furnace is drawn into the hollow support, cools it and passes out into the furnace stack above the convection section. The support beam is cooled by air while the supports on which the shield tubes rest are cooled by conduction, either into the air cooled support or into the shield tubes. Contact of the supports with radiant energy is avoided.
    • 公开了一种改进的支架,用于炉屏蔽管,其位于工业炉的辐射和对流部分之间,并且由于它们暴露于辐射热,所以其受到显着的弱化。 在优选实施例中,中空管用作屏蔽管的梁支撑件,该支撑件被广泛地绝缘,以使辐射热输入最小化,并且由从炉中获得的自然通风引起的通过其中的空气被冷却。 从炉外的空气被吸入中空支撑件中,冷却并排出到对流段上方的炉垛中。 支撑梁由空气冷却,而屏蔽管所搁置的支撑件通过导电冷却,或者进入空气冷却的支撑件或屏蔽管中。 避免支撑与辐射能的接触。
