AS 2593 pdf download.Boilers — Safety management and supervision systems
1.1 Scope
This Standard specifies the requirements for the operation of boilers and other devices including any connected economizer or superheater or deaerator. It includes the special features within the control, management and supervision systems, associated valves and fittings, housing, access and installation for those boilers and other devices operating in the unattended or attended modes. It also details . the checking, testing, supervision and maintenance requirements for each category of attendance to support continued safety.
1.2 Application
This Standard is intended to be used in the design, manufacture, use (with and without attendance) and modification of new and existing boilers as follows: Boilers for fixed land installations. (b) Boilers having a design pressure as shown in Table 1. [c) Boilers having a power output within the capacities specified in Table 1 for the boiler type and category. (d) Boilers in accordance with the checking, testing, supervision and maintenance requirements specified in Table 1 for the boiler type and category. [e) Boilers for the generation of steam, or other vapour, for which the types of boilers permitted are [i) water-tube type or fire-tube type or combination of water-tube and fire-tube types or electric type or all boiler types up to 500 kW (see Table 1) for unattended operation; and (i) any type of boiler for attended operation (see Table 1). [f) Boilers for the heating of water or other liquids at a pressure above that of the atmosphere and to a temperature not less than the normal atmospheric boiling temperature of the liquid, for which application any type of boiler conforming to AS/NZS 1200 is permitted. (g) Boilers having any of the following sources of energy input: (i) Gas fuel (mains or other gases). (i) Oil fuel with a closed flashpoint greater than 23 °C. (ii) Solid fuels, including solid-fuel-in-suspension. (iv) Waste heat fluids. (V) Electric power. (vi) Solar energy. NOTE 1 This Standard may also be applied to boilers outside the limits specified in Items [a) to (g) where equivalent safety and reliability are required by the owner. NOTE 2 This Standard is not intended to apply to miniature boilers in accordance with AMBSC Code Parts 1,2,3and 4. NOTE 3 Except for definitions in Clause 1.4, other clauses in the Standard refer to steam and water only. The Standard may be applied to other fluids with attention by the owner to the owner’s duty care to the operational personnel and the general public. This Standard may be applied at any time determined by the boiler owner or applicable regulatory authority. Regulatory authorities may impose additional requirements, such as design registration, boiler gas supply arrangements, water and sewerage arrangements, electrical arrangements, attendance and supervision by operators and training of operators.
1.4 Terms and definitions
For the purpose of this Standard, the definitions given in AS 4942 and those below apply. 1.4.1 acceptable acceptance accepted equipment or procedure conforms to the Australian Standard applicable to the equipment or procedure, or it can be shown to fulfil the performance requirements of this Standard if no such Standard exists 1.4.2 boilers 1.4.2.1 boiler arrangement of vessels and interconnecting parts wherein steam, or other vapour is generated, or water or other liquid is heated at a pressure above that of the atmosphere by the application of fire or the products of combustion or process, or by electrical or solar means. It also includes valves, gauges, fittings and controls directly associated with the boiler and, where consistent with the requirements of this Standard, includes the boiler setting and associated equipment and other devices Note 1 to entry: It does not include fully flooded systems or pressurized systems where the water or other liquid is heated to a temperature lower than the normal atmospheric boiling temperature of the liquid. 1.4.2.2 attended boiler boiler which requires supervision by a licensed boiler operator (1.4.12) who has effective control of the boiler at all times while it is in use and is in a position to hear the alarms and to respond to them at the boiler immediately 1.4.2.3 unattended boiler boiler intended to operate unattended that includes the addition of special features within the control, management and supervision systems, associated valves and fittings, housing and installation for those boilers together with other devices including the connection of an economizer or superheater or deaerator
