Current through Register Vol. 46, No. 28, July 10, 2024
(a)
						Except as provided for in subdivisions (b) and (d) below, boilers having more
						than 500 square feet of water-heating surface shall have at least two means of
						feeding water. Except as provided for in subdivisions (c), (d) and (e) of this
						section, each source of feeding shall be capable of supplying water to the
						boiler at a pressure of three percent higher than the highest setting of any
						safety valve on the boiler. 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 not be susceptible to the same
						interruption as the other and shall provide sufficient water to prevent damage
						to the boiler.
(b) Except as
						provided for in subdivision (a) of this section, 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 ASME.
(c) For
						boilers having a water-heating surface of not more than 100 square feet, the
						feed connection to the boiler shall not be smaller than 1/2 inch pipe size. For
						boilers having a water heating surface of more than 100 square feet, the feed
						connection to the boiler shall not be smaller than 3/4 inch pipe
						size.
(d) High-temperature water
						boilers shall be provided with means of adding water to the boiler or system
						while under pressure.
(e) A
						forced-flow steam generator with no fixed steam and waterline shall be provided
						with a source of feeding capable of supplying water to the boiler at a pressure
						not less than the expected maximum sustained pressure at the boiler inlet, as
						determined by the boiler manufacturer, corresponding to operating at maximum
						designed steaming capacity with maximum allowable working pressure at the
						superheater outlet.

						design and material of a water column shall comply with the requirements of the
						ASME Code. Water columns made of cast iron in accordance with specification
						SA-278 may be used for maximum boiler pressures not exceeding 250 psi. Water
						columns made of malleable iron in accordance with specification SA-395 may be
						used for maximum boiler pressures not exceeding 350 psi. For higher pressures,
						steel construction shall be used.
(2) The steam and water connections to a
						water column or a water gage glass, including all pipe, fittings, valves, and
						drains, shall comply with the requirements of ASME and section
						14-9.23 
						of this Subpart. These connections shall be such that they are readily
						accessible for internal inspection and cleaning. Some acceptable methods of
						meeting this requirement would be by providing a cross or fitting with a back
						outlet at each right angle turn to permit inspection and cleaning in both
						directions, or by using pipe bends or fittings of a type which does not leave
						an internal shoulder or pocket in the pipe connection and with a radius of
						curvature which will permit the passage of a rotary cleaner. The water column
						shall be fitted with a drain cock or drain valve with a suitable connection to
						the ashpit, or other safe point of waste, and if the water connection thereto
						has a rising bend or pocket which cannot be drained by means of the
						water-column drain, an additional drain shall be placed on this connection in
						order that it may be blown off to clear any sediment from the pipe. The
						water-column blowoff pipe shall be at least three-quarters inch pipe

Current through Register Vol. 46, No. 28, July 10, 2024
Safety valve or valves shall be placed as close to the
						  boiler as possible. No valve of any description shall be placed between the
						  safety valve and the boiler, nor on the discharge pipe between the safety valve
						  and the atmosphere. When a discharge pipe is used, it shall be not less than
						  the full size of the valve, and the discharge pipe shall be fitted with an open
						  drain to prevent water lodging in the upper part of the safety valve or in the
						  pipe. If a muffler is used on a safety valve it shall have sufficient outlet
						  area to prevent back pressure from interfering with the proper operation and
						  discharge capacity of the valve. The muffler plates or other devices shall be
						  so constructed as to avoid any possibility of restriction of the steam passages
						  due to deposit. When an elbow is placed on a safety-valve discharge pipe, it
						  shall be located close to the safety-valve outlet or the pipe shall be securely
						  anchored and supported. All safety-valve discharges shall be so located or
						  piped as to be carried clear from running boards or working platforms used in
						  controlling the main stop valves of boilers or steam headers.

						glasses with independent connections to the boiler, located on the same
						horizontal line and not less than two feet apart. This shall not apply to
						boilers of the locomotive fire-tube type less than 36 inches in diameter, which
						boilers shall have at least two try cocks.

						water and so arranged that the gage cannot be shut off from the boiler except
						by a cock placed near the gage and provided with a tee or lever handle arranged
						to be parallel to the pipe in which it is located when the cock is open.
						Connections to gages shall be of brass, copper, or bronze
						composition.
(b) Where a pipe
						exceeding 10 feet in length becomes necessary, an exception may be made to the
						rule that the gage must be arranged so that it cannot be shut off except by a
						cock placed near the gage and a shutoff valve or cock arranged so that it can
						be locked or sealed open may be used near the boiler. Such a pipe shall be of
						ample size and arranged so that it may be cleared by blowing out.
(c) Each boiler shall be provided with
						one-quarter inch pipe-sized valve connection for attaching a test gage when the
