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 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.

Vacuum, pressure, pressure hot water boiler big contrast: now on the market boilers, boiler diverse species, into the advanced technology to promote the rapid development of the boiler industry. Hot water boiler to provide heat support a large number of all walks of life and living, is one of the important equipment indispensable. According to different boiler under pressure can be divided into the hot water boiler pressure, vacuum pressure hot water boiler and hot water boiler.

Vacuum hot water boiler fuel gas vaporized to produce vaporized overtemperature problems reasons 1000 kw vacuum hot water boiler fuel gas, there are two major surfaces, one is vaporized over temperature, there is a is a partial vaporization, the causes leading to also have different, corresponding solutions are different. If the fuel gas vacuum hot water boiler heating system and hot water circulation loop gravity, it must be open gravity circulation valve. Because once the system failure caused by constant pressure boiler pressure device or system to reduce leakage, the position will not be caused by pressure vaporization system. After this case should an emergency shutdown immediately, and quickly identify the reasons, causing the system pressure to be reduced to exclude faults, the need to make the system running for some time in the cold state, until constant pressure returned to normal in order to determine the role of put into operation again. The local boiler vaporization problems are likely because of poor internal fuel gas vacuum hot water boiler water circulation conditions, the presence of water stagnation zone, tube angle is too small, the water velocity is too low and so on; there may be a forced circulation boiler (back the introduction of improper water distribution pipe layout, flow maldistribution caused when the fuel gas vacuum hot water boiler occur more serious pot of water vapor, combustion equipment should be stopped, but the circulating pump should continue to run at the same time open the occurrence of vaporization backwater valve circuit, to increase the flow of water. when the water hammer tube disappears before gradually returning operation of the combustion equipment.

Hot coals hot water boiler water vacuum filled What water? Water in the vacuum thermal coal boiler, special treatment is deoxygenated, such as high pure water cleaning, washed once injection is completed before delivery from the factory, in a closed loop inside the unit during use (evaporation - condensation - vaporization), during operation in It does not increase not decrease, no supplement or replace in the life of the unit.
