In thu early 1900's, the chemical recovery function was achieved in smelters or roasters wherein black liquor was burnt to recover inorganic chemicals and the heat energy was either wasted or partially recovered. The 1930's to 1950's saw the introduction of tangent tube water wall bidrum boilers which put the emphasis on chemical recovery and also on heat recovery to produce steam for ...
Operation. The major difference between a milling machine and a lathe machine is the relationship of the workpiece and the tool.. Lathe Machines. In a lathe, the workpiece that is being machined spins about it's axis, while the cutting tool does not.
milling machine tapping machine . turning: Turning is a lathe operation in which the cutting tool removes metal from the outside diameter of a workpiece. A single point tool is used for turning.

tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure obtainable is limited by their large shells to about 300 psi. Firetube boilers are used for heating systems.
