5.1-11 Third and Forth Stage Heater Breech Lock and Partition Plate Gasket
(Do not start unless specifically directed by Port Engineer)
The intent of this item is to open the steam side of the third and forth stage heater to
permit access to the heater partition cover for possible change out or repair of same.
Third Stage Heater Data:
Mfr Aqua Chem
Type HP Feedwater Heater
Model 4V - 136C
S/N SP70-10404
The breechlock design makes use of the high pressure feedwater to form a leak proof seal.
The incoming feedwater forces the cover up against an annealed copper gasket. The
copper gasket, similar to a piston ring, is expanded radial between the channel barrel and
the cover to form a seal. The pressure differential between the inlet and outlet water seals
the pass partition cover to seal the pass partitions.
Prior to disassembly of the breech lock, the heater shall be secured from service and
completely drained and vented. All work on the cover and breechlock will be from below
the unit, therefore it is imperative that suitable rigging is provided, that will hold the
cover and keep it from falling. Make necessary removals for access to heater, cover and
breechlock
Remove the channel bar. Carefully pry the Positioning ring loose form the cover. Loosen
all capscrews on the Split Retaining Ring and remove all but two from each of the four
sections. These remaining capscrews will hold the split ring in place as the cover is
jacked to relieve the pressure.

05/04/10 CJ
Set up suitable staging for fitting a jack beneath the heater cover plate. The jack is to be
used to press the cover up into the heater to release the pressure holding the split rings in
place. When the cover has been backed off sufficiently to gain allow for the removal of
the split ring, remove split retaining ring sections.
Remove channel ring. If copper gasket is free remove it and remove cover as follows:
Rig cover to prevent it from falling (est. weight - 400lbs). Carefully, pull cover straight
out ensuring that the cover is square at all times and does not get cocked or else it will
jam.
If the copper gasket is not free, the four sections of the retaining ring must be set up to be
used as strong backs to allow for the careful pulling of the cover.
NOTE: It is extremely important to keep the cover square and even as it is
removed. The tolerances between the cover and the heater shell are extremely tight. Any
deviation will cause the cover to jam. A jammed cover will make disassembly and
assembly IMPOSSIBLE!
With the cover removed only the inlet pass of the tubes are revealed. Remove the bolts
from the pass partition plate. Remove partition plate and gasket.
Take possession of owner furnished spare gaskets and renew. Assemble partition plate
and breechlock in reverse of above. Use Molycoat G Lubricant or a similar lubricant on
the cover and inside of the channel to assist with assembly. Hi Temp Anti-seize to be
applied to all bolting.
Upon completion hydrostatically test heater to prove that the breechlock is leak-free.
Restore all removals to original.
