fbc boiler bed coil duty calculation design

What checks low nitrogen fbc boiler bed cduty calculation design to do on a regular basis? A guarantee accident does not occur during the low nitrogen boiler, enterprises not only need good quality and low price from the procurement of low nitrogen boiler manufacturers boiler equipment, but also for fireman training, so that it could operate the boiler in accordance with safety rules, Moreover, you should regularly check boiler equipment. So low nitrogen boiler needs to be how regularly it? 1, external to the inspection process in the boiler low nitrogen periodically check the state of the external boiler, the boiler housing to ensure that no traces of rust corrosion occurs, and the connection between the various parts of the loose without loosing phenomenon, the appearance of the boiler deformation does not appear. In addition, welds and heat affected zone of the boiler also check there is no defects such as cracks, where necessary, be checked using the surface inspection or other testing methods. 2, a low nitrogen boiler internal inspection requires a lot of internal inspection of the site, wherein for the previous test of the defective parts, the same test methods to be employed, or increasing the appropriate inspection method of flawed or has been subjected to defect repair site focus review retest; head low nitrogen boiler tube plate, furnace combustion chamber and a return header and also must undergo periodic inspection; combustion apparatus in addition also check whether there is a boiler burning, deformation phenomenon. 3, the test needs to be tested to a predetermined pressure boiler pressure tightness and strength member is performed when checking for a low pressure nitrogen pressure boiler inspection, making the hydraulic inspection time to pay attention not to participate in the communication member of the hydrostatic test (such as outside the scope of boiler pipes, safety valves, etc.) should take credible measures to cut off. If the check is carried out at low temperatures, then we will take effective measures to freezing.

Natural gas fbc boiler bed cduty calculation design installation to be done before the preparatory work: With the coal-fired boilers issued the policy is disabled, the provinces and municipalities have begun to clean emissions from the boiler renovation project. Clean natural gas boiler with its unique environmental advantages stand out in many types of boilers, to get food, chemical, medical, heating, construction, hotels, paper and other industrial users alike. After purchased natural gas boiler, the boiler is worried about how to properly install a lot of users do, because once the boiler mistakes during installation will cause all kinds of unintended consequences.

ZG supplies and services biomass-Fuel fbc boiler bed cduty calculation designs as well as providing turnkey boiler plants. For all our boiler plants, we focus on process integration / heat balance optimization, high efficiency, very high availability, high fuel flexibility and open, efficient and proactive cooperation.

June 20 this year, Changji Hui Autonomous Prefecture in Xinjiang Uygur Hutubi County textile industrial park a LOHAS fruit and vegetable plant in the region, two workers were dismantling a height of 20 tons of steam coal-fired fbc boiler bed cduty calculation design chimney 50 meters, which is Finally, the county removed a large tonnage of coal-fired boiler, after the removal of 300 tons per year to reduce coal pollution.

After removal of coal-fired boilers, textile industrial park will access a unified steam heating system, the coal-fired boiler plant will be dismantled access system, both low nitrogen environmentally friendly and energy efficient.

In recent years, Hutubi County to respond positively to China's environmental protection policy, and vigorously promote the "Blue Sky Project", to conduct a comprehensive environmental management and air pollution control activities that will improve air quality as the top priority of economic and social development.

It is understood that Hutubi County this year to increase environmental protection efforts, the New Chemical Materials Park, Textile Park, a new industrial park and other parks coal-fired boilers are dismantled processing equipment, present the industrial park has been demolished 67 companies a total of 98 fuel stations coal boiler, after the removal of 10,000 tons per year to reduce coal pollution.

Secretary Hutubi County Industrial Park Administrative Committee of Economic Development, Sun Xiaotong said: "Industrial Park to good project access, the introduction of new projects, environmental protection must first over that hurdle; increase the park's environmental infrastructure investment , to lay the foundation for entry into the project; increase the industrial enterprises of environmental remediation efforts, requires companies to complete the task of environmental protection standards, to achieve green development, restructuring and development, quality development. "

April 6 this year, Hutubi County has also set tough fight pollution prevention and control headquarters, hand drawn increasing ecological environmental issues reform efforts, strict implementation of environmental protection, "A Pair of responsibility," "party and government with responsibility" layer by layer progressive pressure tight compaction tasks to ensure that environmental issues rectification precise place.

Deputy Director of Hutubi County Office of Pollution Prevention battle command room Zhangxin Hao said: "conscientiously implement the idea of ​​ecological civilization Xi Jinping, the CPC Central Committee and implement the spirit of ecological protection zone state Assembly to do the rectification work to promote the co-ordination of environmental protection issues, and resolutely fight tough fight pollution prevention efforts to build a sky blue green water of the Qing Hutubi.
