complete and tight

2. Make sure the pressure controls are

adjusted properly.

Cleaning The Pressure
Vessel

1. After the boiler has been installed and

before it is placed in service, it is advisable
to clean the pressure vessel to eliminate
any oil film, dirt, or other impurities. Clean
the pressure vessel as follows:

a) Isolate the boiler from the system by

shutting off the main steam valve.

b) Remove the steam safety valve.

c) Mix washing soda or other boilout

chemical with water in a one-gallon
container and pour it into the boiler
through the steam safety valve
opening.

The mixture of washing soda is as follows:

Boiler Size

Soda

12 Kw to 36 Kw

1/4 lb. (114g)

50 Kw to 75 Kw

1/2 lb. (227g)

100 Kw to 150 Kw

1 lbs. (454g)

200 Kw to 300 Kw

1.5 lbs. (681g)

500 Kw

3 lbs. (1362g)

d) If Oxy-Clean is used, then use 1 lb. of

Oxy-Clean per 50 BHP.

e) Replace the steam safety valve.

f) Fill the boiler with water. Water level

is about center in the water gauge
glass.

g) Generate 15 PSI (1 Kg/cm2) of

steam and shut off the boiler. Allow
this hot solution to remain in the boiler
for ten minutes.

h) Drain and flush the boiler twice with

fresh water.

i) To remove all the oil and dirt from the

main steam and condensate return
lines, allow the returns to go into a
floor drain or a safe discharge point
for a few hours of operation.

Alternate method of boiler / feedwater
system cleaning

1. Add Oxy-Clean chemical to feedwater

return tank and allow feedwater pumps
to pump feedwater/chemical into boiler.
Allow boiler to discharge steam enough
to pump 2 complete tankfuls of
feedwater into the boiler.

2. Drain feedwater and boiler, refill, reheat

to steaming and redrain.

3. Refill system and use as required.
