9F-class combined cycle waste heat boiler design features and manufacturing supervisory inspection

. 4) before welding steel materials should base metal, wire fighting spectrum, welding seam after playing spectrum. 5) mounted fin tube finned tube before the deal to pass by the root ball cleaning sponge, the purpose of management is no residue and clean. Welded pipe end at the same time clear the grinding wheel with the wind (including the header pore). 6) the basic header pipe with fillet weld connections are used, it is noteworthy that the fillet weld process requirements should be strictly in accordance with welding welding to ensure special equipment safety in China 6 Volume 25 No. 12 can not occur leakage Because the module is assembled after the basic problem can not be repaired. Fillet weld to be made of 100% surface inspection, where possible, as far as using magnetic particle testing. 7) after passing the pressure test module with special vehicles to transport the module to the drainage sites, the overall pour, requiring water to drain inside the module, and purging with compressed air clean. 7 pipe (tube) manufacturing 1) Each tube butt weld, should be non-destructive testing inspection drawings qualified. Pipe joint weld pipe should be 100% magnetic particle inspection examination. 2) P91 welding materials and welding technology should be strictly in accordance with heat treatment, preheating before welding,[link widoczny dla zalogowanych], welding, argon, after the heat after welding and heat treatment should be. Materials for the P91 weld heat treatment and rehabilitation in the post-exploration should be asked to do hardness tests. 3), low-alloy steel pipes and pipe accessories, piece by piece before use and to make material for spectrum check mark. For high-pressure pipeline, the low-alloy tubes should be not less than three sections of the thickness testing. Medium and low alloy steel pipes and fittings should be done spectra weld inspection. 4) Pipeline Welding should control the deformation, if found excessive deformation,[link widoczny dla zalogowanych], to be calibrated in place. 8 desuperheater design in the actual operation due to various reasons, the steam temperature is always fluctuating, when more than superheater material allowable temperature will also bring serious consequences. In order to control the steam temperature, respectively, in primary, secondary, and between the main steam superheater outlet set a superheater and desuperheater Final Superheater desuperheater in the first, second and between the reheater reheater is also set up an export pipeline reheater desuperheater and the last stage reheater desuperheater. Superheater warm water exports from the high pressure water pump, and then reduce heat to pump warm water from the middle tap (in the pressure water supply.) By warm water through the nozzle spray sprayed into the steam flow in the strong turbulence, the rate of steam and atomized water droplets size is to determine the effect of reduced temperature and the 2 most important factors, therefore, the number of nozzle diameter and the hole is designed desuperheater One of the important parameters. 9, the design of the deaerator extraction-type non-heat boiler deaerator, which is used to HRSG low-pressure steam drum to reduce the dissolved oxygen content of condensate. So bear turbine waste heat boiler heating system, water and oxygen task. The maximum design flow Deaerator 180t / h, design pressure of 0.8MPa, the design temperature of 176 ℃. 10 Conclusion 9F-level waste heat boiler pressure parts mainly by the high, medium, low drum and large composite modules, sophisticated design, layout reasonable, performance art, energy efficient. But the 9F class at run time if the waste heat boiler pressure components in the module when a problem or failure is difficult to repair, so they requested in the manufacture of waste heat boiler must be in strict accordance with the requirements of design and technology,[link widoczny dla zalogowanych], in strict accordance with relevant standards and regulations for the Inspection pot to quality assurance to ensure safe operation.

AQSIQ Song Jihong Special Equipment Safety Supervision Bureau deputy director, Wang Lei Director Lenghao comrades, president of the Chinese special examination homes Lin Shuqing,[link widoczny dla zalogowanych], Liu Shanghua, deputy director of Quality and Technical Supervision, Hebei Province, from the country's 31 provinces special equipment safety supervision departments attended the meeting. Meeting chaired by the Director Wang Lei, Song Jihong made an important speech, Deputy Secretary. Meetings to exchange, summed up the boiler energy regulatory experience using the links to discuss the deployment of next higher energy saving supervision of special equipment. During the meeting,[link widoczny dla zalogowanych], all representatives of the Economic and Technical Development Zone Langfang, Hebei, center of the second heat supply station boiler room of the security and energy management conducted a site observation, was briefed on the application of new technologies for energy saving, energy-saving projects by National Development and Reform Commission of experience, the boiler Housing security and energy management standards activities, such as acceptance of the situation described.
