NOTE: The pressure element is the basic unit that constitutes the pressure part of the boiler.
3.1.5 pressure component
A relatively independent component composed of several pressure elements in a boiler
system.
NOTE: Pressure components include drum, header, water wall, superheater, reheater and
economizer.
3.1.6 non-pressure element
An element that does not bear the pressure of the working fluid.
NOTE: Non-compression elements include load-bearing and non-load-bearing elements. Non-
pressure elements that carry loads include hangers and fasteners.
3.1.7 safety appurtenance
A part or device that is used to protect boiler equipment and prevent boilers from
operating beyond design conditions.
3.1.8 rated pressure
The working fluid pressure at the outlet of the boiler that shall be guaranteed during
long-term continuous operation within the specified water supply pressure and load
range. That is, the rated working pressure or rated outlet pressure marked on the boiler
nameplate.
3.1.9 working pressure
Under normal design operating conditions, the highest pressure that the pressure
element bears.
3.1.10 calculation pressure
The pressure that is used to determine the calculated thickness of the pressure element
at the calculation temperature.
3.1.11 rated temperature
The working fluid temperature at the outlet of the boiler that shall be guaranteed for
long-term continuous operation under the specified design conditions. That is, the rated
steam temperature or rated outlet water temperature marked on the boiler nameplate.
3.1.12 calculation temperature
Under normal working conditions, the metal temperature (arithmetic mean of inner and
outer wall temperatures) of the set pressure element or non-pressure element under load.
the following requirements:
a) According to the principles of safety, reliability and energy saving, design
according to the requirements and needs of the user. Ensure that the energy
efficiency and environmental protection of the boiler meet the requirements of
regulations and users during normal use;
b) A quality system shall be established and run effectively. Be responsible for the
quality of the designed and manufactured boiler products;
c) The correctness and completeness of the design documents shall be guaranteed.
Changes to design documents shall be traceable.
4.3 Installer
The responsibilities of the installer are as follows:
a) Boiler installation shall comply with the provisions of GB/T 16507.8 and the
relevant technical requirements of the installation manual provided by the boiler
manufacturer;
b) The installer shall be responsible for the construction quality of its installation.
