Since 2019, Taiyuan continue to adhere to the principle of priority to improve air quality, in order to significantly reduce heavy pollution weather as the main direction, ongoing action to combat air pollution, management depth to promote coal-fired boiler to achieve 35 tons of steam coal-fired boilers "clear zero".
In accordance with the gas will change, given the need for, after the first stand broken, do not break the principle of non-stand, Taiyuan will continue to carry out the transformation of rural areas, clean heating, heating is expected to complete the transformation of 30,000 before the end of October, the city's rural areas clean heating coverage rate reached 70%.
To reduce coal pollution, coal-fired boiler will also promote the in-depth treatment. October 1, seven more than 65 tons of steam coal-fired boilers and ultra-low emissions completed the transformation. Seven out of 35 tons of steam coal-fired boilers to achieve 35 tons of steam coal-fired boilers all clear.
In the region of the pollution control aspect, the binding improved air quality requirements, the complete electricity instead of coal, coal gas for generation of clean alternative energy area, included in "ban on coal zone", the implementation of joint sheet control. Meanwhile, to further increase the intensity of investigation ban within the "ban on coal zone" small coal-fired facilities, enhance the level of protection clean heating, ensure clean heating effect, and resolutely put an end to bulk coal burning complex, consolidate the "ban on coal zone" construction achievements.
In terms of market control, prohibit the use of more than 1% sulfur, ash than 16% of the civilian bulk coal. Before the end of the civil bulk coal sampling of coal sales business monthly coverage rate of 10%, annual sampling coverage of 100%. Investigated sales of low quality coal units and individuals in accordance with law, concentrate on cleaning up, straighten, banning non-compliance bulk coal supply channels, to crack down on the use of low-quality coal sales behavior, non-coal washery slime, the coal into the civilian market.
Gas-fired boiler high-temperature combustion, on its own and installation quality has a very high requirements, part of the company, three dealers everywhere, once the boiler problem, manufacturers, dealers are missing, consumers can only think of bad luck.
About high pressure steam boiler suppliers in china water hammer faults and solutions 1, boiler water hammer phenomenon a. Issued boilers and pipes at a certain rhythm crash, sometimes loud sound, accompanied by strong vibration water pipes or steam pipes. B. gauge pointer swings back and forth, consistent with the frequency of the vibration noise. c. In the water hammer severe, may lead to the respective connecting members, such as flanges, weld cracking, breakage of the valve. 2, the steam pipe Water Hammer process a. Reduced steam supply, close the main steam valve if necessary. b. Turn hydrophobic superheater header pipe and the steam trap on. c. drum level is too high, the sewage should be appropriate to maintain the normal water level. d. strengthen water treatment work to ensure water supply and boiler water quality, prevent priming. e. When the water hammer arrestor, and the frame status check pipes, flanges, etc., such as a warm-again without damage for the steam supply. 3, the process water pipe water hammer a. Open air valve on water pipe exclude air or steam. b. Enable alternate water supply pipe to the boiler feed water continues. If there is no backup line, take appropriate measures to deal with the fault processing pipeline. c. Check the water supply to the water pump and check valve, if the problem timely maintenance. d. Hold feedwater temperature equalization.
How to distinguish atmospheric pressure hot water boiler and hot water boiler in daily life, people often confuse the pressure hot water boilers and pressure hot water boilers, difficult to discern. In fact, some operators in the industry are nothing more than completely clear detail the differences between the two, let alone teach other people how to identify pressure, pressure hot water boiler and point out both their own characteristics. Below, small series will be divided into three o'clock teach you distinguish the difference between the two. First, look at the furnace pressure changes in pressure hot water boiler and the biggest difference is the pressure. Even the low-cost pressure hot water boiler, the furnace pressure hot water is always consistent with the atmospheric pressure does not change as the temperature changes; the contrary, because the system is composed of soda furnace a sealed container and piping components will naturally follow with increasing water temperature changes. See changes in pressure in the furnace is a more intuitive way to distinguish between the two. Second, look at the professional level control problems because the supply pressure hot water boiler is not operating pressure, the pressure in order to achieve operation of the boiler circulating pump inlet and the outlet is connected to suction hot water in the heating boiler to a user, users return pipe and boiler water inlet necklace, equal to the amount of water into the water. Thus, pressure hot water boiler water level control problems still top box connected to an opening in the drum full of water, the water level control problems. The pressure hot water boiler water level control is no problem, which is one of two significant differences. Third, look at the structure of constraints pressure hot water boiler on the structural parameters of the issue, compared with pressure hot water boiler much simpler. Structurally distinct from strictly limited boiler capacity, parameters, mounting position, etc., only reasonable pressure hot water boiler heating surface arrangement, water circulation to ensure reliable basis, little limitation on the structure, can be largely by actual needs of users to design, construction and installation, flexible and convenient. This is the pressure hot water boiler then more and more important reason for the user's favorite move. In summary, the difference between the atmospheric pressure hot water boiler and hot water boiler mainly in furnace pressure changes, whether the water level under control and whether there are structural limitations in three areas. In fact, the difference between the two is far more than that, they are there is a difference in terms of service life, water supply, safety performance, if you carefully study will certainly find many differences, after contrast, I believe it will not hesitate to choose pressure hot water boiler.
