Boiler Body
1. Place steel profiles (19) which are used
as baseframes of the boiler parallel to each
other as shown in the figure at the l/h side.
The distance from the baseframes vary
from 320 mm to 970 mm as the number of
sections vary from 4 to 9.
2. Start assembly with rear section (1), clean all rope grooves on the section using a wire
brush. Clean nipple ports and nipples using cloth and paraffin. Apply adhesive to the rope
grooves on the front side of the section. Fix continuous lengths of 10 mm rope (5) in each
groove starting with the outer groove as shown in following picture. Tape each end of rope.
Apply jointing compound onto nipples, and place nipples (4) squarely in each nipple port
and, using a wooden mallet, lightly tap nipple into the port to secure.
3. Take an intermediate section (2) and prepare the section as described above. Place
rear section at the end of baseframes. With its unroped side facing towards the rear, fit
the intermediate section squarely onto nipples of the rear section and secure by using
a wooden mallet. Ensure that the rope on the rear section remains in correct position
NOTE: Do not fix rope into the grooves of the side of the intermediate section facing the
rear section. Likewise, apply the same procedure for the following sections applying one
rope between two sections.
4. Continue boiler assembly repeating the same procedures with the other sections.
Apply "Compression Tools" passing them through bottom and top nipples as shown in
following figure, and accordance with the table headed "Usage of Compression Tools",
until the rope between each section is firm. The gap between each section should be
3-4 mm.
