Terms and definitions For the purposes of this document, the terms and definitions given in GB/T 2900.48 and the following apply. 3.1.1 water-tube boiler boiler in which the flue gas flows outside the tube on the heating surface and the working substance flows inside the tube [Source: GB/T 2900.48-2008, definition 3.1.21] 3.1.2 boiler proper whole boiler composed of drum, water (steam-water) separator, water storage tank, heating surface, header and its connecting pipes, furnace, combustion equipment, air preheater, furnace wall, flue (air) duct, framework (including platform and escalator), etc. 3.1.3 connecting pipe unheated steam (water) connecting pipes between headers and between header and drum 3.1.4 pressure element element subjected to pressure of internal or external working substance Note: A pressure element is the basic unit to compose boiler pressure component. 3.1.5 pressure component relatively independent component composed of several pressure elements in a boiler system Note: Pressure components include drum, header, water-cooled wall, superheater, re-heater, economizer, etc. 3.1.6 non-pressure element element not subjected to pressure of working substance Note: Non-pressure elements include load-bearing and non-load-bearing elements, and load-bearing non-pressure elements include supports, hangers and fasteners. 3.1.7 safety appurtenance appliance or device for protecting boiler from operating beyond design conditions 3.1.8 rated pressure pressure of working substance at the boiler outlet that shall be guaranteed during long-term continuous operation within the specified feed water pressure and load range, i.e. the rated working pressure or rated outlet pressure marked on the nameplate of the boiler 3.1.9 working pressure maximum pressure borne by the pressure element under normal design operating conditions 3.1.10 calculation pressure pressure used to determine the required thickness of the pressure element under the calculation temperature 3.1.11 rated temperature temperature of working substance at the boiler outlet that shall be guaranteed during long-term continuous operation under the specified design conditions, i.e. the rated steam temperature or rated outlet water temperature marked on the nameplate of the boiler 3.1.12 calculation temperature metal temperature of pressure elements or load-bearing non-pressure elements (i.e. the arithmetic mean of the internal/external wall temperature) which is set under normal working conditions Note: It is also commonly known as “calculated wall temperature”. 3.2 Symbols For the purposes of this document, the following symbols apply. p——the rated pressure, MPa; Rm——the lower limit of standard tensile strength of material at room temperature, MPa; ReL(Rp0.2)——the standard yield strength of material at room temperature, MPa; ——the yield strength of material at design temperature, MPa; ——the endurance strength of material at design temperature (105h), MPa; ——the creep strength of material at design temperature (1×10-5%/h), MPa; θ——the quality coefficient of cast steel. 4 Responsibilities 4.1 User The user shall determine the
