摘要：
An air passage in the wall of a refuse burning furnace is cleaned by means of a sleeve, which normally is used for governing the air flow by axial displacement of one of its ends within the passage proper. This sleeve is mounted so it can be occasionally pushed right through the passage and furthermore in such a manner that air is prevented, in use, from passing into the sleeve, whereby the latter may be used for inspection purposes.
