Burner fault recognition and Remedy: Start the burner is a prerequisite for the normal operation of the boiler, one supporting auxiliary burner gas boiler is the most important equipment. If burner fails, it may result in severe cases whole boiler can not be used. So, how to identify and exclude burner fault it? Fast boiler small series to answer your questions. First, if the boiler burner ignition failure to start three times in a row failed to ignite, it is determined that the ignition failure. Troubleshooting as follows: 1, the gas pressure can not be maintained if the phenomenon of misfiring in 3-5kpa, too high or too low will. 2, too much throttle burner ignition vain many times can easily lead to the phenomenon. 3, when using the burner, the ignition voltage if the ignition is not, or when the ignition electrode dirty or wrong position, there will be ignition failure. 4, valve block will promptly turned on the ignition when the normal, open and could hear the sound, no open flame, so if the boiler valve group fails, it will not fire. 5, there may be ignition failure caused by the ignition controller, if the ignition controller fails, it will not lead to the normal ignition.

In mid-June, Yingtan City, Jiangxi Province issued a "Yingtan City People's Government Office on the issuance of three-year action plan to win Yingtan City Blue Sky Battle (2018-2020 years)", Yingtan City Market Supervisory Authority proposed by file stringent targets execution, to carry out a three-year coal-fired boiler special work within the city.

The special rectification, on the basis of thorough investigations within the jurisdiction of coal-fired boilers, the high standard, high-efficiency coal-fired boilers to complete the rectification work to ensure that by the end of 2018 as required successfully completed. 10 out of 21 local stations steam tons / hour and coal-fired boilers and started to build the city and out of the city of 35 tons of steam coal-fired boilers of work; involving the transformation of coal-fired boilers, technical testing organizations should strictly follow the relevant safety technical specifications strict technical clearance, and the overdue completion of the rectification of the enterprise be severely punished according to relevant laws and regulations. Coal-fired boilers by special campaigns, effectively reduce pollutant emissions, improve air quality, help Yingtan beautiful building.

Up to now, the council investigation of coal-fired boiler unit 16, a total of 21 Mopai boiler units, 12 units have been removed, and the rest are in the boiler rectification. Next, the council will further strengthen the regulation of coal-fired boiler follow-up supervision, to ensure that regulation effect.

Inspection 6 tons of steam boiler optimization papers 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.

The primary failure is due to corrosion associated with varied biomass materials fuel.This failure mechanism is the result of alkali-related chemical attack which creates compounds that be easily eroded.A secondary concern is the inappropriate use and application of the refractory material.This is less of a concern in CFB boiler that are not used to co-fire biomass.
