nature gas fired boiler applied in school in tunisia
Recently, market supervision bureau issued the Notice on Strengthening the National Energy Board within the scope of the power station nature fired boiler applied in school in tunisia 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.
Startup nature fired boiler applied in school in tunisia steam temperature does not mention how high do? A: In the unit to start the process, often encounter steam pressure has reached the requirements, and the steam temperature was too much difference, especially in front of the turbine and the blast furnace or red switch occurs. Should take the following measures: appropriate to increase the amount of coal to improve the furnace heat load; adjust the secondary air ratio, increase the amount of lower secondary air; improve wind, air pressure, increased gas velocity; hydrophobic and full of air and exhaust mother pipe in front of the main steam isolation all hydrophobic.
8 ton condensing fuel gas-fired nature fired boiler applied in school in tunisias in Russia
ZG boiler re-export project—a full set of 8 tons of condensing fuel gas-fired boilers was exported to St. Petersburg, Russia. As the economic power of Russia, St. Petersburg takes industry as the main development point, and is a highly developed international city of science, technology and industry. Therefore, the selection requirements for production equipment are very high. The ZG boiler oil and gas boilers feature the internationally popular classic “all-wet-back three-return” design structure, FRG flue gas recirculation, condensation prevention and control, and other special technical advantages to enable Russian customers to successfully sign a complete set of 8 tons of WNS with ZG boiler within a week. Type saturated steam boiler contract, the fuel is natural gas and diesel. In addition, based on Europe's strict boiler emission standards, ZG boiler has configured pure Italian imported burners for customers.
The difference between ordinary and low nitrogen nature fired boiler applied in school in tunisia boiler:? With vigorously promote environmental protection department of China's low-nitrogen boiler being applied more and more common. In the eyes of many low nitrogen boiler just meet environmental protection to reduce emissions, but in reality not. The following describes a low nitrogen boiler manufacturers to distinguish the conventional type boiler and low boiler nitrogen for everyone? A difference in emissions due to the different combustion grate firing, combustion chamber, circulating fluidized bed boiler, the furnace of different structure, but also its original NOx emissions when large differences, in general, not specifically for low NOX combustion furnace using technology, circulating fluidized bed original low NOx emissions, NOx raw emission Stoker furnace represented by a chain slightly lower, industrial pulverized coal boiler as burning boiler room, the higher the NOx emissions original, well-known domestic boilers have low nitrogen emissions is greatly reduced. Second, different boiler technology, layer combustion, combustion chamber, circulating fluidized bed boiler may be different with different low NOx combustion technique in accordance with the combustion mode, the combustion boiler for the air distribution layers using an air classifier, and more often to achieve low flue gas recirculation nitrogen combustion; under the influence of a typical flue gas recirculation combustion boiler combustion zone layer, in conjunction with the air fractionation techniques for reducing NOx by catalytic char; super reduction furnace denitration technology in recent years, new furnace denitration techniques, by position reasonable combustion flame spray region ammonia, direct denitration at a high temperature flame. Low Nitrogen mainly the secondary air boiler, the coal to the location and distribution of optimal adjustment of the mouth, or the like to increase the flue gas recirculation system. Third, different security, the center layer after combustion, combustion chamber, low-NOx combustion furnace circulating fluidized bed boiler technology a large number of tests performed, it has been verified in engineering applications, in general, a low nitrogen boiler, security to be higher, the reason for its sales in recent years more and more, there are many users because of its high security, a threat to the space environment small purchase, which is one of its important differences with ordinary boilers.
