Recently, market supervision bureau issued the Notice on Strengthening the National Energy Board within the scope of the power station boiler piping material quality safety risk prevention and control (the "Notice"), to further enhance the quality and safety supervision and management of boiler tubes, effectively preventing security risks, protect the power production safety , as follows.

First, carry out the verification of boiler tubes

The electricity business, special equipment manufacturers to immediately organize boiler tube inspections, to verify whether the focus of the pipe to meet the technical conditions stipulated orders, including the source, size, quantity, quality certificates, raw material procurement contracts, procurement contracts and other piping components. For imported pipe material, but also the verification of the customs declaration, commodity inspection report (proof of entry inspection and quarantine of goods), combined with the production, inspection and testing during use and operation of the situation, in-depth investigation pipe quality boiler safety issues and risks.

Second, effectively prevent security risks

Boiler pipe quality and safety hazards or other problems threatening the security and stability of power station boilers, power companies, special equipment manufacturers to take practical measures immediately, the complete elimination of quality and safety problems; there are significant quality and safety problems, it should stop running generator sets , boiler or stop production and sales of the pipe elements, and replace the boiler pipe complying with relevant standards.

The actual boiler pipe manufacturing unit is unknown or if there are doubts, the relevant information or data can not be traced authenticity, power enterprises, special equipment manufacturers to immediately in accordance with industry standards, inspection and testing institutions have entrusted the appropriate qualifications for boiler tubes were identified test. Test results show that failed boiler or pipe quality does not meet the technical requirements stipulated in the order, power companies, special equipment manufacturers to eliminate hidden dangers in a timely manner or be replaced.

Third, strengthen the source of control boiler pipe

Special equipment manufacturing enterprises, power enterprises should strengthen boiler pipe source control, in strict accordance with the standard provisions of China's relevant laws and regulations and orders technical conditions agreed to carry out boiler pipe design and manufacturing, procurement orders, admission acceptance, inspection and testing, installation and commissioning work, resolutely eliminate substandard or counterfeit boiler pipes enter the field of electricity production; to strictly implement the special equipment safety supervision and management regulations, establish and improve the technical archives and long-term care, to ensure that relevant information can be traced back.

Special equipment manufacturing enterprises, power companies are finding there are significant quality and safety risks of boiler tubes, to report to the local market regulators, power management departments and the National Energy Board sent energy regulators, and to take effective measures to thoroughly rectification to ensure the safe operation of generators . Provinces, autonomous regions and municipalities and Xinjiang Production and Construction Corps Market Authority (Hall Commission) should work together with the same level of power management departments, the National Energy Bureau sent energy regulatory agencies and other units, the organization of supervision and inspection, supervision and hidden rectification, effectively preventing security risks.

Commissioning of Boiler gas boiler commissioning must be carried out after the hydrostatic test. Before commissioning, should be a comprehensive inspection of each furnace parts, electronic control devices, wiring, etc. are normal, water supply, oil furnace if opened, electrical contacts are in the set position. 1, depending on the size of the fuel consumption, the initial damper, the hydraulic pressure. 2, the power is turned on, the power switch to open the cabinet, the water pump starts furnace, (if the pump is rotated into the anhydrous, pump purge valve is opened, the air exhaust pump). 3, control checks whether the normal water level electrode. 4, check the burner operation is normal. Starter burner starts combustion when the water level rose to a predetermined level, the start of combustion is normal to observe: Start no vibration noise, stable combustion, no smoke, orange yellow flame, burning bright clear. Otherwise, to make the appropriate adjustment (refer to burner instructions). Note: The oil pressure between 0.8 ~ 1.0Mpa, after a good tune, do not easily change, oil pressure is too high or too low have an effect on burner performance life. 5, check the pressure gauge pointer swing is smooth, with or without loosening stuck. 6, whether the discharge check valve is set at the set pressure steam: Pressure controller first maximum working pressure, a safety valve is adjusted to the set pressure higher than 0.05MPa, when the furnace pressure was raised to whether the exhaust pressure setting, if exhaust , pulling the safety valve a few times, and try again, if not enough to deal with safety valve to adjust. Pressure relief valve setting: boiler rated pressure + 0.03MPa. 7, check the electrical contacts of the operation: When the pressure is raised to the maximum working pressure (not exceed the rated working pressure), should stop burning, open the safety valve blowing off steam, the pressure to a minimum operating pressure (maximum operating pressure is generally lowest set to 0.10MPa), combustion burner should be restarted. Note: When the adjustment screw should slow, especially when the pointer approaches the end, otherwise, damage the screw off the wire.

Boiler fire phenomenon, how to do 1, furnace pressure fluctuations or to limit and alarm. 2, no flame detector flame, flame flameless television display. 3, flue gas oxygen abnormal fluctuations. 4, steam pressure steam temperature dropped drastically. 5, furnace black, black smoke chimney. 6, the flue gas temperature is reduced. 7, MFT action, turbine trip, splitting the unit. Cause 1, the furnace combustion conditions organizations unreasonable, improper wind coal proportion. 2, the load is too low, unstable combustion conditions without oil combustion vote, or vote, although oil but not good combustion results. 3, cast oil, poor quality oil, oil spray gun is bad, low oil pressure, oil system failure. 4, poor coal quality, coal is too rough, the water is too large pulverized coal combustion adjustment is not timely. 5, the primary air temperature, air pressure is too low. 6, boiler MFT protection action. 7, a large area of ​​the furnace coke collapse, smashing off the flame. 8, severe water wall pipe explosion will blow out the flame. 9, all coal-fired condition, mill pulverizing system failure caused most or all trips. 10, a part of auxiliary machinery such as a fan, blower, fan, air preheater tripped, causing unstable furnace combustion conditions. 11, sootblowing properly, resulting in a large number of normal operation of the furnace ash effects of fire inspection of the boiler. 12, bottom seal damage. Treatment 1, the boiler fire, MFT should be action, otherwise manual MFT. 2, normal inspection device linkage linkage MFT, confirm that all fuel cut. 3. quickly identify the cause, try to eliminate the boiler can be re-ignition, the recovery unit operation. 4, when the mill started again after the trip, the trip must be the primary air tube mill full purge. 5, the MFT operation, checks, Fan normal operation, automatic furnace vent. 6, the MFT movement, check all the secondary purge air damper position is set, the total air volume is automatically adjusted to 30 ~ 40% BMCR sufficiently purged air volume. 7, the MFT operation, when the turbine is in a state disk drive, the disk drive must continue until the normal turbine eccentricity, before re turn red. 8, if temporarily unable to identify or eliminate the cause, restart and could threaten personal safety equipment, non-start. 9, processing according to the corresponding predetermined remaining MFT.

Gas-fired fired steam boiler price in chandrapurs and coal-fired steam boiler which is more energy-efficient? General business in the procurement of steam boilers were more often or consider production efficiency problem, we need to know what kind of fuel steam boilers more energy-efficient choice is clear, and that is the most common gas and coal-fired steam boiler steam boiler comparison which is more energy efficient? Following on from me give you an analysis. Clear answers to the same model or coal-fired steam boiler energy saving compared to steam boilers, we can roughly be calculated next-ton per hour boiler work at full capacity to 150-160Kg according to the market value of coal fuel, and gas to around 80m3 of gas. A further additional energy means 'gas' is higher than the calorific value of 'coal' fuel value, and then under the same conditions, producing one ton of steam, of course, fast burning gas. Also a ton of water to generate a tonne of steam, in theory, as much heat energy is required, the low single coal market price, it is cheaper than burning gas. But better to burn coal gas and environmental protection in environmental protection. If a large amount of production if the proposed biomass boiler, coal processing than such low investment, but also more environmentally friendly.
