Shell Boilers -- Part 1: General Requirements
1 Scope
1.1 This Part of GB/T 16508 specifies the general technical requirements for the
material, design, fabrication, inspection, safety accessories, combustion system,
installation, operation, energy-saving and environment protection of stationary shell
boilers.
1.2 This Part is applicable to the stationary pressure shell boilers with water as
medium, evaporating heating surface mainly arranged on shell OR boiler furnace
arranged in shell which meet the following conditions:
a) Steam boiler of which the water volume at the design normal water level is
greater than or equal to 30L, and the rated steam pressure is greater than or
equal to 0.1MPa (gauge pressure; the same below);
b) Hot-water boiler of which the rated outflow pressure is greater than or equal to
0.1Mpa, or the rated power is greater than or equal to 0.1MW.
1.3 This Part is not applicable to the following equipment:
a) Portable boiler (e.g. marine boiler, railway locomotive traction boiler);
b) Cooling devices required for equipment and process flow cooling;
c) Boiler for military use.

Safety release pressure
The pressure of safety valve upon releasing, also referred to as set pressure of safety
valve.
3.6
Hydrostatic test pressure
The pressure applied when conducting hydrostatic test for boiler system or pressure
component (part) as required.
3.7
Rated temperature
The working fluid temperature at the outlet which shall be ensured for long-term
continuous operation under specified design conditions.
3.8
Calculating temperature

temperature along the metal section of part).
3.9
Test temperature
The metal temperature of pressure part in pressure test.
3.10
Required thickness
