FULTON VSRT Series Installation, Operation And Maintenance Manual page 67

SECTION 3
VSRT-IOM-2022-0728
In addition to commissioning the boiler, the service technician will also familiarize
boiler room personnel with the operation of all Fulton equipment. Personnel
must be qualified to understand the basic operation and function of controls.
Prepare for Initial Start-Up
These instructions are for use when the unit is being started up for the first
time, or after prolonged shutdown. They are to be used in conjunction with the
information in Daily Start-Up section of this manual.
Perform Boil Out
Fulton recommends boil out is accomplished prior to boiler system operation.
This procedure ensures that all oils, sealants and other organic compounds that
may cause erratic water level control are removed from the boiler and piping.
Consequently, if boil out is not accomplished prior to system operation, erratic
water level control and surging may occur. Fulton strongly recommends that a
boiler chemical specialist be consulted for the purchase of chemicals for boiler
cleaning.
ƒ Boil Out Procedure
Fulton recommends pressure vessel cleaning prior to system operation or after
major maintenance. This boil-out procedure removes oils, greases and other
organic compounds that may cause erratic water level control and surging. There
are many chemicals on the market that may be used and our recommendations
are as follows:
ƒ
Fulton recommends the use of washing soda (sodium carbonate) to wash
out boilers. Sodium carbonate (also known as washing soda or soda
ash), Na2CO3 is a sodium salt of carbonic acid. Called washing soda, soda
crystals, or sal soda in the detergent section of stores, it effectively removes
oil and grease.
ƒ
Trisodium phosphate (TSP, E339) is an excellent degreaser and alternative
to washing soda. It is a white, granular or crystalline solid, highly soluble in
water producing an alkaline solution. The item of concern is often partially
hydrated and may range from anhydrous trisodium phosphate, Na3PO4,
to the dodecahydrate, Na3PO4·12H2O. Most often found in white powder
form, it can also be called trisodium orthophosphate or just plain sodium
phosphate.
Adhere to the following when performing boil-out:
1. The boil-out shall include "over-the-top" wasting of water. A temporary
2" pipe shall be run from the relief valve tapping to a suitable point of
discharge as required by local jurisdiction(s) to assure that grease and oils
are floated to the top and out of the unit. Minimum time for the procedure
shall be four (4) hours of constant water discharge alternating between
bottom and top blowdown. At least two (2) complete bottom blowdown
and complete refills shall be done. A suitable manner of chemical waste
handling shall be employed to meet local jurisdictional requirements.
