Inspection 6 tons of china manufacture 2 ton rice husk fired steam boiler pressure parts of introduction 1, the steam boiler Safety Supervision boiler if the following conditions to deal with various internal and external inspection and pressure parts overpressure test. (L) disassembly, after conversion and shifting means; (2) stops running and resume operation requires more than one year; (3) pressure-receiving element after major repairs; (4) according to the boiler operation, the state of the device must doubt when tested. 2, the boiler before the test is completed stopped, the elimination of the internal scale external boiler ash, soot, yet necessary to dismantle the furnace wall and the insulation cover, the following check Key: (l) when the drum welds, holes and the like are normal , for leakage; (2) presence or absence of corrosion of the boiler plate, where the groove from deformation and the like; (3) waterwall tubes are not bent, deformation, etching, etc. inflated; (4) a pyrotechnic tubes are not bent, the tube plate out and gusset weld cracks; (5) to the water pipes, sewage pipes and the welding drum presence of a defect. 3, severe corrosion do accounting should be done before the super strength test. 4, before the hydrostatic test should do the following tasks (l) portion of the test, the internal management and Pu inspection surface; (2) to check the clogging of pipes; gauge (3) is mounted in the modified inspection (no less to 2); (4) change means drains and purge valve. 5, in a hydrostatic test shall meet the following requirements: (l) hydrostatic test shall be carried out when the ambient temperature is higher than 5 ℃, measures should be adopted or against the cold. (2) filled with water boiler, if the metal surface condensation, should be removed, a preliminary check for leaks and then slowly open the booster, when raised to 3kg / CM, a check should be carried out, can be tightened if necessary manholes , hand holes and flange bolts; (3) when the water pressure up to operating pressure, the opening pressure should be temporarily stopped to check for any leakage of each portion, and then increased to the test pressure for 5 minutes and then back down to the operating pressure checks, meet the following requirements is eligible. ① In the test pressure was raised, the pump stops, the pressure drop must not; no leakage in the outer weld ②; ③ watermark (traces of water) may or tears (not downflow drops) not being replenished weld; ④ Water after the pressure test, visual observation found no residual deformation.

Boiler superheater and reheater difference and a secondary air ratio explanation: the boiler, because it is the site of the main and important product, so its knowledge and understanding, is necessary to achieve a comprehensive and specific, and, on its knowledge of the content, you can not have a shred of omission. So, in order to let everyone compliance as soon as possible, and at the same time, can also be the proper use of the boiler, below, followed by a wish to learn of its work, beating let us benefit from it. 1. On the boiler manufacture and installation, for manufacturers, what are the requirements? In addition, the boiler water, which generally have several situations? Boiler manufacture and installation of the manufacturer, the provisions of its requirements, is: has made manufacturing unit boiler manufacturing license, boiler units for benzene product transformation and installation is no need to obtain a permit of another. Boiler water, generally speaking, is there are two cases, one is a slight lack of water, the second is a serious water shortage.

Acid cleaning method by using an appropriate amount of hydrochloric acid or nitric acid liquid corrosion inhibitor formulated and injected into the boiler descaling. Effect scale pickling solution is the role of dissolution, peeling and loose, so as to achieve the purpose of cleaning.

Continue to promote the comprehensive management of dust pollution, coal-fired pollution control to strengthen and deepen the industrial pollution control and related fields, etc., which are from governance "Xining City 2018 air pollution comprehensive management action plan." Xining City, the official launch of construction on the "Xining blue" and maintain the action. Aspects of dust, industrial pollution, coal pollution will increase management and control, to develop specific control measures for building a better Xining efforts.

Since the launching of "Xining blue" action in the coal-fired pollution control, Xining City has accumulated more than 3,000 tons of steam "coal to gas," the task of governance, the main city of the city "coal to gas" campaign to take the lead. With the further implementation of the Blue Sky Project, Xining substantial increase in utilization of clean energy, significantly improve air quality of the environment, it has been among the five northwestern provinces in the forefront of the capital city.

Taking into account the special Xining City, Qinghai-Tibet Plateau is located in the geographical location, the winter heating season is longer, coal dust is an important source of winter air pollution, while heating pipeline dredge more difficult, the implementation of the transformation plan will face difficulties pipeline reconstruction. To effectively improve urban air quality since 2013, Xining City, carry out a comprehensive "coal to gas" governance by supporting comprehensive measures upgrading natural gas pipeline network, such as the yellow car out of standard co-ordinate the promotion of winter clean, safe and efficient heating, achieved within the natural gas pipeline network coverage coal to gas works full coverage.

To promote the implementation of clean energy projects, Xining City, expand the scope of the ban on coal to 166 square kilometers, and implementation of the "coal to gas" in the natural gas pipeline network range, achieved in the area of ​​coal-fired boiler "cleared." Increase coal trading market will be rectified, completed a five coal market and coal two 49 business outlets, effectively reducing the use of inferior coal pollution on the surrounding environment.
