22) The Boiler is now ready to put into service or on standby.
In stubborn cases, another boil-out may be necessary by repeating steps (1) to
(22) above, or, by conducting a seventeen-step procedure for Boil-out with Surface
Blow-off in GAMA-HI Operation and Maintenance Manual for Steel Boilers (Including
Water Treatment).
4.9.3 If not to be used, the Boiler shall be drained, flushed, and inspected. The
surfaces are then thoroughly dried by means of hot air. If the boiler room is dry and well
ventilated, the Boiler may be left open to-the atmosphere. An alternate procedure is to
use suitable moisture absorbent, such as quicklime or silica gel, which is placed, in the
Boiler in a suitable location. The Boiler is then tightly closed. Every two or three months
the Boiler should be checked and the lime gel replaced or regenerated, if necessary.
4.9.4 The outside surface of the Boiler should be insulated and jacketed to prevent
unnecessary heat loss from the shell. By reducing the heat loss from the Boiler,
excessive boiler room temperatures are avoided and better operation economy can
be obtained. Packaged Boilers are jacketed at Easco factory. If done on the job, this
is usually not accomplished until the Boiler has been in operation for a week or so to
ensure joint tightness.
4.9.5 The Boiler must be fired at a low rate for at least one day to dry out the refractory
linings. Adjust the firing apparatus for a low firing rate and operate intermittently to keep
combustion chamber warm. Drying procedure should be carried out together with the
boil out.
4.10 Cleaning a New Steam Boiler
Oils, greases and sediments that accumulate in a new Boiler and piping must be
removed from the system in order to prevent an unsteady water line and carry over
of the water supply main above Boiler. Operate the Boiler with steam in the entire
system for a few days allowing the condensate to return to the Boiler. If the condensate
temporarily be wasted, operate the Boiler only for the length of time it takes for
condensate to run clear. If the latter cannot be achieved or if the condensate is returned
to the Boiler, boil out the Boiler using the Surface Blow-off connection.
The Boiler then can be cleaned by the following steps:
1) Drain Boiler until water is just visible in gauge glass. Run a temporary pipeline from
the Surface Blow-off connection to an open drain or some other location where hot
water may be discharged safely. Do not install valve in this line.
NOTE:
Certain State and Local Codes may restrict the use of some of the chemicals
listed for cleaning and maintaining the Boiler. Check with local authorities before
proceeding to use any chemicals.
2) Drain about 5 gallons of hot water from Boiler into a container and dissolve into it
tri-sodium phosphate at the rate of 1 lb of tri-sodium phosphate per 50 gallons of boiler
water. Refer to boiler specification sheet for boiler water content in pounds and divide
