3 Terminologies and Definitions
For the purposes of this document, the terminologies and definitions defined in GB/T 2900.48 as well as the following ones apply.
3.1
Boiler setting
Outer wall of boiler constructed or laid with refractory material, thermal insulation material, etc.
3.2
Drying-out
Process for drying the boiler setting at certain temperature rise speed and with certain holding time by igniting or other heating methods.
3.3
Boiling-out
Method of heating, deoiling and cleaning for 24h~48h at 0.5MPa~2MPa as well as passivating the internal surface of metal after injecting the mixed solution of sodium hydroxide and trisodium phosphate.
3.4
Service hours, SH
Hours of operation state.
4 Basic Requirements
4.1 The boiler installation organization may carry out boiler installation within the permissible range of the license only after obtaining the corresponding qualification according to those specified in Boiler Installation and Alteration Enterprises Supervision Administration Regulation (TSG G3001).
4.2 Prior to construction, the installation and construction organizations may carry out construction only after informing the special equipment safety supervision department of the boiler equipment installation condition.
4.3 The boiler installation work shall meet those specified in Boiler Safety Technical Supervision Administration Regulation (TSG G0001), and the installation process shall be subjected to the supervision and inspection of national special equipment safety supervision and inspection organization; the boiler failing to pass the supervision and inspection shall not be put into service.
4.4 Qualifications of operating personnel for welding or non-destructive testing shall meet those specified in GB/T 16508.1.
4.5 During the installation of boiler, in case of quality problems (pressure component influences safe application), the installation shall be stopped.
4.6 After the completion of boiler installation, the installation organization shall hand over the relevant technical data to the using organization within 30 days after acceptance.
4.7 Boiler using organization shall establish safety technology file of boiler equipment.
5 Foundation Inspection and Marking Out
5.1 Before boiler and its auxiliary equipment are put in place, the foundation dimension and position shall be inspected, and the permissible deviation shall meet those specified in boiler equipment technical document; if there is no requirement, the permissible deviation shall meet those specified in GB 50273.
5.2 Before shell boiler installation, vertical and transversal installation reference lines as well as elevation reference point shall be marked.
6 Steel Frame Installation
6.1 Before steel frame installation, the quantity of members shall be checked against construction drawing and such primary members as upright column, girder, etc. shall be inspected, and the permissible deviation shall meet those specified in boiler equipment technical document; if there is no requirement, the permissible deviation shall meet those specified in GB 50273.
6.2 The steel frame installation requirements are as follows:
a) As for steel frame installation, the elevation line should be determined first according to upright column;
b) After the upright column is put in place, the column foot shall be fixed on the foundation according to design requirements; in case it is necessary to fix by welding to embedded reinforcement, it shall be welded firmly;
c) Platform, bracket, escalator, railing, rail post and foot baffle shall be installed straightly and welded firmly; the spacing between rail posts shall be uniform; the surface of weld at the joint of railing shall be smooth;
d) The length and inclination of escalator as well as the spacing between upper/lower foot board of escalator and connection platform shall not be modified at will.
e) Hole should not be drilled at will on such members as platform, escalator and bracket; in case it is inevitable, after the hole is drilled, reinforcement measures shall be taken.
6.3 The permissible deviation of steel frame installation shall meet those specified in boiler equipment technical document; if there is no requirement, the permissible deviation shall meet those specified in GB 50273.
