Recently, Wuhan City, introduced in 2019 to embrace the blue sky action plan for speeding up the optimization and upgrading of industrial structure, promote the optimization of energy structure adjustment, implementation of transportation restructuring, deepen industrial pollution control and other tasks proposed solution.
Among them, in terms of optimization and upgrading of industrial structure, we will study and formulate more stringent industry access threshold, no new heavy chemical and paper industry projects within 1 km of the Yangtze River and Hanjiang River shoreline. Strict implementation of ecological protection red line, the bottom line of environmental quality, resource utilization on the line, environmental access a list of constraints.
In optimizing the energy structure, the city's ban on new coal-fired generating units, supporting the construction of new projects is prohibited owned coal-fired power stations, will not be new coal-fired boilers. Increase efforts to promote green buildings, new buildings full implementation of green building standards. In deepening the industrial pollution control, referring to Beijing and Xi'an subsidies, launched a comprehensive transformation of low nitrogen gas boiler. Before the end of 2019, the district completed at least 50% of the area within the low-nitrogen transformation tasks 10 steam tons / hour or more gas-fired boiler.
Inspection 6 tons of steam electricity boiler for sale 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.
