low preasure boiler
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 low preasure boiler 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. "
How should conclude that there is lack of water steam low preasure boiler plant accident when water has less than the minimum designated level, but still can be seen when the water level in the water, mild little water; when the water meter can not see the water for severe water shortages. Summarized the situation listed below: (1) water is less than normal water drum points delineated; (2) ultra-low level alarm, automatic warning sounded, the alarm lamp Shiner; (3) superheating steam temperature rise; ( 4) the amount of water supply is not normal, less steam flow rate value; (5) the exhaust gas temperature rises.
This is just the introduction of a provincial subsidy low preasure boiler renovation policy, Shaanxi, Shanxi, Hunan, Jiangsu, Tianjin and other places have introduced a subsidy policy response, which is enough to show the importance the government to treat the atmospheric environment, and for boiler companies a friendly attitude.
Why low preasure boiler always pay? Phenomenon: the pressure gauge shows the value of frequent falling, falling. Normal water pressure of the boiler must be greater than 0.8bar, replenishment cycle in 3-6 months or more. The boiler is connected to the cooling system in the room together to form the heating system. Pressure gauge is displayed on the boiler pressure value of the entire heating system, so that the replenishment is the replenishment of the entire heating system. Therefore, in most cases often pay a heating system problems that may arise, not the problem of the boiler. One reason: in the pre-commissioning of the new system heating system commissioning new air heating system more automatic exhaust valve release system results in reduced pressure, requiring multiple replenishment. Two reasons: heating system for leaks out pipe heating system or ground heat sealing leakage may occur at the interface and the leaks little leakage, since the heating boiler is in the state of the whole system is hot, so the leakage the rapid evaporation of the water is difficult to find the leak by the naked eye. If the pressure off the boiler and can not appear to find the leak, we recommend that you check the boiler leaks. Inspection method: After stopping the boiler operation, close the bottom of the heating boiler supply and return valves (the valve can ensure shutting), disconnected from the system directly to the boiler, the boiler supply water to an integer value, a period of observation to see if there are fluctuations in pressure gauge . This method may be simply determined to be a problem after the boiler or heating system piping valve leakage problem. Reason Three: The expansion tank expansion tank failures would result in failure of the boiler heating system pressure exceeds 3bar the boiler drain valve protection. Contact your dealer for a replacement. Four reasons: replenishment valve closed lax if replenishment valve closed lax and low pressure water pipe network, the system will fall in pressure when using hot water. Solution: If frequent replenishment of the situation, need to contact the service provider, check the heating system as soon as possible to avoid long-term damage to the boiler caused by replenishment.
