These groups of tubes offour each can be readily removed through the stationary boilers of this make have, instead of a groupof tubes, a single tube of a somewhat larger sectional area. Over this nest of tubes, and like unto the outer shell of aboiler, there lie two cylindrical steam chambers, of which theupper one contains steam only when the boiler is in service,while the lower one is half filled with water and steam. All of the front tubes open with free communication intothe lower st
