of the boiler (Picture 5.1, pos. 22). Boiler fume pipes must be cleaned by opening the upper boiler
door and removing smoke spins. The boiler heating surfaces are recommended to clean as often
as possible, since clean heating surfaces increase boiler efficiency. Deposits or soot layer on the
surface cannot be thicker than 3 mm.
When cleaning the 2
nd
stage fume pipes, soot deposits from a boiler flue pipe must be removed
every time upon cleaning the boiler funnels. Ash and soot must be removed through a special
opening, closed with a lid on the side of the flue pipe (Picture 5.1, pos.10).
8. REQUIREMENTS FOR SAFE OPERATION
8.1. The following safety requirements must be applied to water heating boilers UT - 100, UT - 150,
UT-200, UT-250, UT-320 UAB UT boilers, manufactured by CJSC “UT KATILAI“. For the purpose, it is
required to use the below listed organizational and technical measures.
8.2. Organizational Measures
After installation works, an owner of a boiler (boilers) must ensure that:
-
a boiler (boilers) is (are) included to the company's list of potentially dangerous equipment
and specify its number in the boiler certificate;
-
a responsible person for boilers (boilers) maintenance has been assigned, by recording
his/her data in the boiler certificate;
-
the first inspection after the installation has to be performed at the presence of an expert of
any republic (having a relevant permission) public authority. the inspection results must be
recorded in the boiler certificate;
-
the boiler certificate must be completely filled in;
-
boiler servicing must be administered by persons not younger than 18 years old, having
passed the compulsory operational safety briefings, and their knowledge on fire safety,
operational and safety at work has been checked.
-
during operation, an owner of a boiler (boilers) must ensure boiler technical maintenance
inspections in due time (see section 9 of these instructions) to follow technical safety
measures, controls, and timely instrumentation verification listed in clause 3.8;
-
a boiler-station, as a power facility, must be recognised by the State Energy Inspectorate as
suitable for use.
Boilers' operating personnel must ensure an order in boiler-station rooms and around the
outside facilities, that is, not to block passages, not to store unnecessary items in the boiler-
station, not to overload flue pipes with flammable items, not to store combustible or explosive
materials in the boiler-station, to clean the boiler-station and its installations on a regular basis.
By controlling and by using instrumentation, by paying attention to certain external signs
(water leakage outside the piping or fittings; smoking through collars from the boiler or flue pipes;
the emergence of unusual sounds: water bubbling, rattle, squeak of rolling bearings, etc.),
evidencing an abnormal functioning of heating systems, boiler (boilers) operating personnel must
constantly control a boiler’s (boilers’) parameters and sizes and technical condition of the overall
boiler-station equipment. All boiler equipment malfunctions, occurred during a shift, must be
recorded in a logbook. Apart from these malfunctions, the logbook must be used to record
equipment shutdowns, boiler cleansing, performed during the shift, details of the operating
personnel, and if required, work schedules and assignments.
