The reason condensing gas boiler fouling fouling What is the boiler is condensing gas boiler maintenance and repair should focus on issues, not only because fouling threat to the safe operation of the boiler, but also greatly increase the cost of maintenance and repair boilers, boiler shortening life. For boiler fouling problems, we should be in-depth analysis of its causes, promptly take effective preventive measures to provide effective protection for the safety, energy conservation, economic operation of the boiler. (1) a carbonate, sulfate scale carbonates, sulfates reasons of scale formation due to condensation gas boiler is the presence of calcium, magnesium, carbonates, sulfates, etc. to the solubility in water decreases with increasing temperature, to a certain extent will precipitate scale. Carbonate scale, is generally formed in the heated places less intense; sulfate scale precipitation is generally at a high temperature, often occurs in the heating surface heated relatively strong, and it is in the waterwall tubes of the boiler convective tube bank common. (2) Chemical composition of silicate scale mainly aluminum silicate scale, iron silicate compound, the chemical structure is more complex, this scale hardest texture, and very poor thermal conductivity, so the maximum harm, in general forming a high thermal condensing gas boiler load tubes. (3) the main component is iron scale iron oxide scale iron compound, condensing gas boiler in normal operation, the oxygen content of the water is very low, oxygen does not cause corrosion of the boiler. However, if the increase in dissolved oxygen, can lead to corrosion of metal surface oxide, iron oxide generated in the boiler product was dissolved in water, and at high temperature, the iron oxide scale formed gradually. For scaling condensing gas boiler safe and economic operation of harm it is very large, because it's hidden features, easily overlooked, but the boiler accidents caused due to scale accounts for a large proportion. Only by understanding the reasons for fouling produced, find a solution, by taking appropriate measures to avoid fouling, in order to ensure that the boiler safe fundamentally, run the economy.

The end of December 2019, Guanzhong Plain, basically should be changed to make change, the mountains and strive to complete the transformation of the whole village contiguous 60%, the rest of the region before the end of 2020 to complete the transformation. It has completed the transformation to strengthen regional security and stability of power supply and electric heating facility security management. Encourage public bodies to give priority to use high efficiency air source heat pump, storage electric heating and other products.

2, and steadily push forward coal to gas. Gas will adhere to the reform, on the basis of strict implementation of the contract on the amount of resources, natural gas pipe network coverage area of ​​priority implementation of coal to gas. Accelerate the construction of infrastructure such as natural gas pipeline network, expanding coverage of natural gas. In accordance with the principle of special matter, to speed up the preparatory work for the pipe network, gas station facility construction land, planning permission and so on, to simplify examination and approval procedures, to speed up the examination and approval, and actively support the gas company to promote the project implementation plan. Encourage and support the network does not cover the better the basic conditions of township (town, street) using a skid mounted LNG and compressed natural gas. An annual increase of gas from coal to gas priority for rural residents and incorporated into the contract management to ensure stable gas heating. To ensure energy conservation, the indoor installed gas boiler energy efficiency of not less than level 2. According to Mopai base number, speed up the development of sub-annual indeed given village households from coal to gas embodiment, reasonably determine the 2019, 2020 annual scale coal to gas.

3, increase geothermal and other renewable energy heating efforts. Geothermal resources better urban plains of Xi'an, Xianyang City and other urban and rural interface, focusing on rural construction area of ​​more than 20,000 square meters of new residential, with technical and economic feasibility of using geothermal heating premise should be encouraged to have the condition the old district were geothermal heating transformation. Urban construction must be carried out as a heat source point in principle new waste incineration plant. Encourage and support the strength of the research institutes and enterprises to strengthen the solar thermal, biomass energy technology research and development, improve systems integration. Township (town, street) party and government institutions, enterprises and railways, roads and other auxiliary services take the lead in building a number of sites for renewable energy heating demonstration projects.

4, to promote the use of clean coal. Will not have the clean energy alternative conditions and mountainous areas will not have the coal to electricity, coal to gas to actively promote clean coal. In accordance with reasonable layout, standardized management requirements, improve the construction of clean coal distribution centers, to achieve full coverage of clean coal. Distribution center to establish and improve coal quality inspection and sales ledger system, in line with the sales of clean coal, "coal quality coal for civilian goods" (GB34169-2017) and "civil coal coal quality goods" (GB34170-2017) technical requirements, city , loose coal and coal county built-up areas and its surrounding area used to reach No. 1 product technical requirements, other areas prohibit the sale, use more than 1% sulfur, ash content higher than 16% of civil bulk coal, the information contained the bulk coal management online platform, to achieve dynamic monitoring information. Strengthen commercial coal sales, circulation of coal quality control, increase sampling efforts to achieve full coverage of monthly sampling to crack down on the use of inferior coal for sales behavior. Study and perfect the counties (cities, districts) financial subsidies to support clean coal policy, and actively promote the use of clean coal, to ensure that people warm winter.

5, continue to carry out comprehensive improvement of coal-fired boilers. Increase the small coal-fired boilers and furnaces tea, operating the stove, grain storage and drying equipment and other efforts to eliminate coal-fired facilities. Before the end of 2019, the Guanzhong area of ​​all 35 tons of steam coal-fired boilers (20 tons of steam and above with the exception of ultra-low emission renovation has been completed) all removed or implementation of clean energy transformation. In accordance with the principle of gas will change, the implementation of clean coal prior to transformation Area off central heating station.

The selection of industrial boilers depends on which issues to start buying

Production and development now require huge amounts of thermal energy, and industrial boilers can be used to provide thermal energy. We usually use electricity, water, food and clothing in life involved in the industry, as well as heavy industry need it to provide rich heat. Therefore, for industrial and commercial enterprises, the choice of a good boiler is particularly important, then we choose high-quality and durable industrial boilers to see what problems?

1, looking at the quality of industrial boilers, generally speaking, high-quality industrial boiler noise will be relatively small, the boiler itself noise will reduce its vibration, make its system relatively stable, so that it can make its service life longer. The main material of the high quality industrial boiler will be thick and pressure resistant, and the exterior of the boiler will be treated with anticorrosion, so that its service life will be longer and safer. So when we choose boiler, we can look at its quality and then choose it.

2, look at the energy-saving performance of industrial boilers. Industrial boilers will consume a huge amount of fuel and produce a lot of waste emissions when they operate, thus consuming a large amount of money and causing environmental pollution. Domestic professional industrial boilers in saving raw materials and reducing carbon emissions in the technical level is more outstanding. So when we choose, we can know more about whether the boiler saves fuel or not and whether it is environmentally friendly and the energy-saving technical achievement of the boiler manufacturer, and then make a comparison and carry on the selection.

3, looking at the quality of its after-sale guarantee service is also a very important question when choosing a good industrial boiler manufacturer, then why is it important? If the selected manufacturers provide us with a good after-sales service, then we can reduce unnecessary waste of manpower and material consumption, will have a better boiler experience. There are many factors to consider when selecting industrial boilers. We can mainly consider the quality of the boiler itself and the strength of its energy-saving performance.
