A general increase in the standard of environmental governance, Huzhou City, Zhejiang Province closely follow the direction of development policy, will gradually phase out coal-fired hef 042f s 3 pass fire tube boilers or adapted for the gas boiler. According to statistics, Huzhou City Nanxun five years has eliminated nearly 3,000 small coal-fired boiler, saving 720,000 tons of coal resources.
Remediation process, district departments form a joint working group, while the seizure of small boilers, while helping business transformation. Behind the small boiler one Taiwan "puff", representing a small wood processing, printing and dyeing, textile and a number of high pollution and high energy consumption enterprises. They only destroyed the visual landscape, but also pollutes the lies to be the region's transformation and upgrading process must break the "pots and pans."
Huzhou referred morning Decoration Co., the person in charge mentioned: "In the past coal-fired boiler pollution does not say, but heating is not stable, press only a day after more than 300 wood boiler replacement, productivity improved significantly, now at least a day. can be pressed more than 500. "this shows once production efficiency improvement, enterprise back to the speed can be increased to a year.
After the disappearance of small boilers, or to benefit a lot of people around. "Our village is known for the production and processing of small wood gathering, the family opened the window every morning before'll see a row of chimneys in the distance 'spit black smoke'. Now grinding temperature, steam generator replaced the original coal boiler, surrounding environment has improved significantly. "FEATURE before the flood who lives in the village of Lao Shi sincerely laments.
Improvement in the area of active removal of small boilers companies subsidies, also made detailed provisions on subsidy amount of different types of boilers. Meanwhile, the district has built South Lake thermoelectric, thermoelectric GCL, Guodian three cogeneration projects, the laying of 200 km of heating pipe network, and the end of last year to achieve full coverage of central heating.
For hot water hef 042f s 3 pass fire tube boilers, water treatment program is a must do, agree metal corrosion engineering equipment industry were as important. Hot water boiler proper treatment, not only can it improve the thermal efficiency of 20% -40%; also enhance the life of equipment 1-2 times, to obtain a more powerful boiler efficiency.
Poor quality, slow development pressure hot water hef 042f s 3 pass fire tube boiler manufacturer has developed rapidly, the emergence of product oversupply situation, some manufacturers technical weak, poor manufacturing quality, and competition among manufacturers is fierce, lower prices, and some even the manufacturers cut corners. Design is not standardized. Compared with pressure hot water boiler pressure boiler, there are notable feature, especially in the heat and water power, and therefore the structural design pressure hot water boiler should be consistent with its own characteristics. Pressure hot water boiler design but not standardized, no thermodynamic calculation for calculating and hydrodynamic design, the design pressure hot water boiler substantially in the form of an opening to the boiler on the basis of pressure only, as other configurations copy, resulting in poor water circulation boilers, waste of energy.
