What is BS EN 12952-7 - Water-tube boilers and auxiliary installations about?
This part of BS EN 12952-7 specifies the essential requirements for equipment and protective devices for a water-tube boiler plant as defined in EN 12952-1, to ensure the boiler operates safely within the allowable limits (pressure, temperature, etc.). BS EN 12952-7 mentions the general requirements for steam boilers and hot water generators, additional requirements for plants without manual intervention, and the final inspection of the water tube boiler plant.
Note 1: Additional requirements especially needed for boilers without manual intervention are specified in Clause 7.
Note 2: Requirements for equipment for chemical recovery boilers are given in Annex A.
Who is BS EN 12952-7 - Water-tube boilers and auxiliary installations for?
BS EN 12952-7 on water-tube boilers and auxiliary installations is useful for:
- Equipment safety
- Water-tube boilers
- Heating equipment
- Flow and pressure control
- Quality control management
Why should you use BS EN 12952-7 - Water-tube boilers and auxiliary installations?
Water-tube boilers are mostly used to generate high-temperature, high-pressure steam. This boiler's internal structure features a small steam drum and narrow tubes. This boiler's components produce high-volume vapour for high-capacity applications. BS EN 12952-7 is a part of the EN 12952 series concerning water-tube boilers and auxiliary installations consisting of the following parts:
- Part 1: General
- Part 2: Materials for pressure parts of boilers and accessories
- Part 3: Design and calculation for pressure parts of the boiler
- Part 4: In-service boiler life expectancy calculations
- Part 5: Workmanship and construction of pressure parts of the boiler
- Part 6: Inspection during construction, documentation and marking of pressure parts of the boiler
- Part 7: Requirements for equipment for the boiler
- Part 8: Requirements for firing systems for liquid and gaseous fuels for the boiler
- Part 9: Requirements for firing systems for pulverized solid fuels for the boiler
- Part 10: Requirements for safeguards against excessive pressure
- Part 11: Requirements for limiting devices of the boiler and accessories
- Part 12: Requirements for boiler feedwater and boiler water quality
- Part 13: Requirements for flue gas cleaning systems
- Part 14: Requirements for flue gas DENOX-systems using liquified pressurized ammonia and ammonia water solution
- Part 15: Acceptance tests
- Part 16: Requirements for grate and fluidized-bed firing systems for solid fuels for the boiler
- CR 12952 Part 17: Guideline for the involvement of an inspection body independent of the manufacturer
- Part 18: Operating instructions
Although these parts may be obtained separately, it should be recognized that the parts are interdependent. As such, the design and manufacture of water-tube boilers require the application of more than one part in order for the requirements of BS EN 12952-7 to be satisfactorily fulfilled.
