Dongying City, Shandong Province in response to low-nitrogen coal-fired sizing of water tube boilers, industrial waste heat recycling and other environmental policies, combined with local conditions, Dali urban and rural areas to promote clean heating projects, and achieved remarkable results. As of mid-October this year, Dongying City clean heating rate of more than 72%.
Recently, Dongying Municipal Urban Management Bureau to the outside world, in order to further promote the urban and rural clean heating, it has already shut down 10 coal-fired boilers environmental non-compliance of a total of 155MW.
After shutting down 10 coal-fired boilers environmental non-compliance, Dongying City high environmental standards were established in a total of four 58MW gas-fired boiler and a total of four 70MW coal-water slurry boiler through a series of energy-saving treatment, flue gas emissions much higher than the index of new environmentally friendly ultra-low emission requirements.
Meanwhile, Dongying City, the original heating effect is also unsatisfactory 4.33 million square meters of heating regions to establish a uniform heating systems, and the use of standards to ensure clean heat source; higher operating costs for the original 2.17 million square meters of heating area heat source replacement process, both to ensure good heating effect but also saves a lot of money.
According to statistics, this year the city of Dongying city plans to add a total area of clean warm 8.1138 million square meters, down to the next new clean heating in rural areas 45000.
Recently, Dongying City issued a "Dongying City 2018-- 2020 coal consumption reduction alternative work" (the "Program"), after the completion of the city's 10 steam tons / hour and small coal-fired boilers zero and start steaming for 35 out of work t / h coal-fired boilers and, as of 2020, out of 35 steam tons / hour and coal-fired boilers.

Pressure hot water sizing of water tube boiler tube boilers and small rust How it works: boilers, hot water boilers of this kind can be said that it is common and common species, but also has many applications, and moreover, it is the product website. So, the next will continue this topic in order to advance the process of learning the product and at the same time, to increase their expertise in this area, rather than nothing, in turn, affect everyone's learning speed and learning efficiency. 1. hot water boilers, pressure equalization tube which has a specific role? Even water boiler tube, which in particular use, there are mainly the following, are as follows: First, the high pressure gas withdrawal; Second, to maintain the pressure inside the pressure equalization vessel. Third, it is in the electrical system, voltage balance. Therefore, it is an important part, there is an important role. 2. The hot water boiler operation, required fireman card? This, then, there is no doubt that the answer is required, and, in addition to hot water boilers, boiler other, there is also a need for an operator's license fireman. Because, most of the boiler, for special equipment, so that will have this requirement, and hot water boiler, which is a boiler. In addition, the fireman card, which also have different levels and different levels, there is a corresponding boiler size, so, at this point, you can not go wrong. 3. Small hot water boiler rust, which is the main method there? In addition, it can be avoided? Small hot water boiler, rust of this work, if you want to be specific, it is the caustic soda may be used, such as sodium hydroxide, is heated and pressed, then, maintained for more than 24 hours, after which the waste water discharged can . If you want to avoid this problem, then, is to use a water softener to ensure that the water quality furnace.
Dongyang selective attention things have gas hot water sizing of water tube boiler, which has several customers in the choice of a lot of gas hot water boiler, because the technique does not exist, often do not know how to sell. Since the gas hot water boiler of many styles, and not as the layout, not the same producers, many of whom are still do not know how to choose the next to teach the public fairly small component of the selected knowledge. First, select the appropriate gas hot water boiler, gas hot water boiler must first figure out the layout of the facility should be set up in the application of regulation, inspection and maintenance should also, therefore absolutely reasonable layout can be carried out smoothly. Also, each gas hot water boiler saturated steam will pay part of the money, but for the moment we will have a part in the application of consumption, which should be firm in the choice of gas hot water boiler style special attention, to summarize good intentions and then make a selection. Thirdly, a place worthy of attention is gas hot water boiler has a lot of facilities, those are excellent assist effect can be more good to reduce energy consumption, save energy saving. Therefore, gas hot water boiler in the selection process, which some of the content on the absolute pay special attention to, so you can choose to suit the goods, to facilitate more good applications.
