price gas boiler vertical

Recently, market supervision bureau issued the Notice on Strengthening the National Energy Board within the scope of the power station price boiler vertical 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.

Chemical prevent high temperature corrosion of price boiler vertical waterwall boiler chemical improvements to prevent high temperature corrosion improvements waterwall 1, using an anti-art windshear main principle is offset by a spray angle of air flow injection port, and the original jet forming a motion , the opposite direction of rotation, in tangentially running smaller diameter, due to the opposite running direction of the initial movement of the main gas flow direction of the gas flow in the furnace after the anti-wind shear, the pulverized coal injected hindered high-temperature air upstream of the primary air flow and the time, the pulverized coal injection speed is reduced rapidly, enhancing coal dead time in high temperature zone, to enhance the combustion efficiency of pulverized coal. By using an anti-wind shear can effectively prevent high temperature corrosion phenomena, and can enhance the ability to stabilize combustion in the boiler furnace, reduced coke boiler case, as shown in FIG. 2, using the technology of Side by side wind technology is mainly on the high temperature zone waterwall corrosion or high temperature corrosion installed upstream of the injection port area, and ejecting the air in the furnace boiler. Technology is mainly employed side air can be controlled in the high-temperature reducing gas corrosion area, enhanced oxygen content in a local range. 3, to improve the control operation to take excess air coefficient increases, a plurality of coal mills is not put into operation at the same time, reduce the coal particle size, increase the air preheater ash fouling preventing plugging of equipment and operation control systems such as high temperature measures to prevent High temperature corrosion phenomena.

Since 1945, ZG has built a world-wide reputation as a producer of performance dual fuel oil gas fired steam price boiler verticals, combining high-quality manufacturing processes with a passion for exploring new ideas and technologies largely ignored by longer established competitors.

Four coal-fired price boiler verticals precautions to meet a variety of fossil fuels and natural gas sectors of production, often require boiler, the general common is to transform into a coal-fired furnace gas-fired boiler, to change the high fuel costs of coal on the environment cause serious pollution problems, specific issues unique boiler is not a small project, you need to pay attention to a good close links with each transformation in order to avoid failure of transformation, on boiler should be noted that we have to understand the following description. 1, the original boiler demolition work; boiler before carrying out the original host and auxiliary boilers need to be demolished, concrete demolition work carried out by professional staff, in order to more quickly complete the demolition work with but also to prevent the demolition process in the event of any accident; 2, note that pressure capacity of the boiler; small boiler into the gas by the coal-fired, also changed the original negative and positive pressure combustion burner, the process you need to pay special attention throughout the furnace wall the structure and sealing, the sealing function, it might cause the boiler after the transformation could not withstand the pressure and accidents; 3, furnace renovation precautions; when in many cases will change the gas burner, because the fuel mist of poor or incomplete combustion of the fuel gas remaining in the furnace a little mistake will cause fire or explosion, it is carried out after completion of the transformation for an explosion vent installed in an appropriate position to prevent the explosion, while additional ignition flame protection means after the boiler guarantee safe operation; 4, after the transformation of the test; after the completion of high-quality boiler transformation, but also the need for reuse Sophisticated testing to confirm their safety, commonly used test method is boiler pressure after the transformation of high-pressure test, and finally pass a test meet the standard may be considered completed after the entire transformation boilers. Caution visible through major transformation over the course of gas boilers, boiler reconstruction requires not only technical but also need to meet the relevant standards in order to ensure more successful boiler and can be smoothly carried out using, of course, in the transformation of the former users need to analyze the structure of the entire boiler study, confirming boiler renovation project can be re-introduced in order to avoid unnecessary waste.
