Connecticut Administrative Code › Title 29 - Public Safety and State Police › 232 - Boiler Design, Construction, Installation, Repair, Use and Operation › Existing Installations - Power Boilers › Section 29-232-54 - Age limit of existing boilers

Current through July 10, 2024
(a) The age limit
				of any boiler of nonstandard construction, installed prior to the date the act
				became effective, shall be 30 years except that, after a thorough internal and
				external inspection, and when required by the inspector, a hydrostatic pressure
				test of one and one-half times the allowable working pressure and held for a
				period of at least 30 minutes, during which no distress or leakage develops,
				any boiler having other than a lap-riveted longitudinal joint may be continued
				in operation at the working pressure determined by Sec.
				29-232-55.
				The age limit of any nonstandard boiler having lap-riveted longitudinal joints
				and operating at a pressure in excess of 50 psi shall be 30 years; this type of
				boiler, when removed from an existing setting, shall not be reinstalled for a
				pressure in excess of 15 psi reasonable time for replacement, not to exceed one
				year, may be given at the discretion of the chief inspector.
(b)
Maximum allowable working pressure
				of standard boilers.
The maximum allowable working pressure of standard
				boilers shall be determined by the applicable section of the code under which
				they were constructed and stamped.
Connecticut Administrative Code › Title 29 - Public Safety and State Police › 232 - Boiler Design, Construction, Installation, Repair, Use and Operation › Existing Installations - Power Boilers › Section 29-232-56 - Age limit of lap joint fire tube boilers

Current through July 10, 2024
The age limit of a tubular, flue or cylinder boiler having a
				  longitudinal lap joint and operating at a pressure in excess of fifty psig
				  shall be thirty years. A reasonable time for replacement shall be given by the
				  commissioner. All lap seam boilers in this state 30 years or older shall have
				  the long seam exposed for annual examination for detection of a possible lap
				  seam crack. A typical lap seam crack extends approximately parallel to the line
				  of the rivet hold of a longitudinal seam, and near the edge of the rivet heads
				  as shown in figure 1.
Figure 1.
Click here to view image.
To determine the existing condition of the riveted lap joint
				  type seam, the seam should be notched and slotted. Figure 2-A illustrates a
				  slot approximately 3/16 inch inside, extending 2/3 of the thickness of the
				  plate in depth and about 1-1/2 inches in length, cut from the outer surface and
				  so located that its center will be on a line with the edges of the rivet heads
				  of the inner row. One quarter inch diameter holes drilled 2/3 through the
				  plate, so a hole will be at each end of a slot, with the material between the
				  holes removed with 3/16 inch cape chisel, forms a satisfactory procedure of
				  cutting the slot, which, it will be noted upon referring to figures 1 and 2
				  will cross the path of a lap seam crack if one exists adjacent to that line of
				  rivet holes. Generally, three slots per course are sufficient. One slot is cut
				  at the center of the course and one on each side, midway between the center and
				  the girth seams.
The application of a hydrostatic test not exceeding one
				  hundred fifty percent (150%) of the safe working pressure will be sufficient to
				  cause leakage at the slot if a lap seam crack has extended through 1/2 of the
				  thickness of the plate. If there is a lap seam crack present, which has not
				  developed through 1/3 the thickness of the plate, leakage will appear when the
				  crack finally reaches the bottom of the slot; Therefore, the slot should not be
				  closed or covered after the test.
The outside surface of the inside plate of the seam should be
				  exposed for examination by cutting a "V" notch, as illustrated in figure 2-B.
				  The removal of the small section of the outer plate at the caulking edge
				  uncovers the plate underneath.
The notch should have an angle of 90°, or as near thereto
				  as possible, while retaining the normal lap between the edge of rivet hole and
				  the caulking edge of the plate. Care should be taken when cutting the V-notch
				  to avoid tool marking the under plate of the seam, as that plate must be clean
				  and polished to some extent for a thorough examination. A magnifying glass
				  should be used for this purpose.
The boiler may be returned to service if no defect is
				  found.
Connecticut Administrative Code › Title 29 - Public Safety and State Police › 232 - Boiler Design, Construction, Installation, Repair, Use and Operation › Existing Installations - Power Boilers › Section 29-232-57 - Pressure on old boilers

Current through July 10, 2024
In no case shall the maximum working pressure of an old
				  boiler be increased to a greater pressure than would be allowed for a new
				  boiler of the same construction.
(a)
				Cast iron headers and mud drums: The maximum allowable working pressure on a
				water tube boiler, the tubes of which are secured to cast iron or malleable
				iron headers, or which have cast iron mud drums, shall not exceed one hundred
				sixty psig.
(b) Pressure on cast
				iron boilers. The maximum allowable working pressure for any cast iron boiler,
				except hot water boilers, shall be fifteen psig.
Connecticut Administrative Code › Title 29 - Public Safety and State Police › 232 - Boiler Design, Construction, Installation, Repair, Use and Operation › Existing Installations - Power Boilers › Section 29-232-59 - Boiler feeding and feed piping

Current through July 10, 2024
All boilers shall have a feed supply which will permit the
				  boilers being fed at any time while under pressure. A boiler having more than
				  five hundred square feet of water heating surface shall have at least two means
				  of feeding, one of which shall be an approved feed pump, injector or
				  inspirator. Where a source of feed directly from pressure mains is available at
				  sufficient pressure to feed the boiler against a pressure three percent greater
				  than the release pressure of the safety valve with the highest release setting,
				  this may be considered one of the means. For boilers that are fired with solid
				  fuel not in suspension, and for boilers whose setting or heat source can
				  continue to supply sufficient heat to cause damage to the boiler if the feed
				  supply is interrupted, one such means of feeding shall be steam operated. A
				  boiler fired by gaseous, liquid or solid fuel in suspension may be equipped
				  with a single means of feeding water provided means are furnished for the
				  shutting off of its heat input prior to the water level reaching the lowest
				  permissible level established by the code. The feed water shall be introduced
				  into the boiler in such manner that it will not be discharged close to riveted
				  joints of shell or furnace sheets or directly against surfaces exposed to gases
				  at high temperatures, or direct radiation from the fire.
The feed piping to the boiler shall be provided with a check
				  valve near the boiler and a valve or cock between the check valve and the
				  boiler. When two or more boilers are fed from a common source, there shall also
				  be a valve on the branch to each boiler between the check valve and course of
				  supply. Whenever a globe valve is used on feed piping, the inlet shall be under
				  the disc of the valve. In all cases where returns are fed back to the boiler by
				  gravity, there shall be a check valve and stop valve on each return line, the
				  stop valve to be placed between the boiler and the check valve and both shall
				  be located as close to the boiler as is practicable. Where deaerating heaters
				  are not employed, it is recommended that the temperature of the feed water be
				  not less than 120°F to avoid the possibility of setting up localized
				  stress. Where deaerating heaters are employed, it is recommended that the
				  minimum feed water temperature be not less than 215°F so that dissolved
				  gases may be thoroughly released.
