Since 2017, located in Changchun City, Jilin Province to accelerate the governance of coal-fired function of the boilers within the city out of small coal-fired boilers remediation process. Up to now, the work has achieved initial success.
15 in the city with 20 kilowatts and above the coal-fired generating units, 13 units have ultra-low emissions; city table 292 with 20 t steam / hour or more coal-fired boilers, emission standards have reached the count 253 male , accounting for 86.64% of the proportion of the boiler with; the city built area of 10 steam tons / hour small coal-fired boilers 2962 units, out of a total of 29553 units, up 99.7% out of proportion, the basic completion of the national requirements out of the task.
In order to further improve air quality, improve people's living environment standards index, Changchun City by expanding the ban on burning area, improve the standard phase-out of coal-fired boilers, plans to use two years of urban 20 tons of steam / h coal-fired boiler (kiln) furnace eliminated.
By the end of 2017, the city has eliminated 20 tons of steam / hour coal-fired boilers 964 units; at the same time to speed up the central heating and (expanding) network as well as the pace of clean energy promotion, provide for the transformation of the city's coal-fired boiler control a strong guarantee.
In recent years, Changchun City, adhere to the full implementation of coal-fired boilers governance, to improve ambient air quality in Changchun City has played a positive role. 2017, good days Changchun 276 days, compared with 2013, an increase of 35 days; heavy pollution days 10 days compared to 2013, reduced by 33 days; major air pollutants respirable particulate matter (PM10) and fine particles (of PM2.5) were 78 mg / m and 46 micrograms / cubic meter, respectively, 39.5% and 37.0% decrease over 2013.
20 tph SZL series biomass fired function of the boiler project for rubber industryA steam boiler is an important equipment in rubber industry, proving adequate steam support for multiple production processes including drying, profiling and vulcanizing. Jiangsu General Science Technology Co., Ltd. is a modern high-tech enterprise specializing in R&D, production and sales of tires, which is a subsidiary of Hongdou Group. It is one of the leading companies in China's all-steel heavy-duty tire market.In the context of global economic integration, Jiangsu General Science Technology Co., Ltd. built a new production base in Thailand in January 2019. The performance of the steam boiler has an direct impact on the quality of the complete production line. After the multiple comparisons and investigations, General Science chose to cooperate with ZOZEN. According to the actual working conditions of the Thai production base, ZOZEN recommended the SZL series biomass steam boiler. This new type of biomass-fired boiler has the advantages of compact structure, safety and efficiency, and sufficient output. According to the characteristics of the fuel, the ZOZEN technicians rationally optimize the design of the feeding hopper, the width and length of the grate; the large furnace volume reduces the heat load and prevents the occurrence of coking in the furnace. Meanwhile, the boiler adopts a light chain grate, and segmented wind bunkers and wind regulating devices are arranged in the lower part of the grate to meet the air volume required for the fuel in different combustion stages, which achieve precise air distribution to ensure full combustion of fuel, so that the thermal efficiency can reach over 88%, and all indicators have reached the international advanced level.
Electric heating function of the boiler of a Note, pricing execution can not be destroyed in accordance with the pad sealed to prevent damage to the fuel injector. In the use of the process, electric boiler safety valve to be carried out once a day move to ban rust lose their qualities. All that part of the inspection work is completed in the future, we need to put all the tools and materials belong to the set up into which the designated place, and then after a good safety record deal with queries and to prepare for work. All of the above is turned into electrical boiler maintenance methods, we have to check carefully the implementation in order to ensure a safe warm winter. Second, the price of heating execution time living in what the Chinese have a climate, is a happy thing, also something that can not be a good thing. After all, a little more about the world of life experience can only be considered, every winter the course, the elderly are particularly cold, many need to spend the winter heating equipment as a major essential goods. Third, the heating operation of the embodiment tariff embodiment only elderly people use electric heating stove according to the normal operation, no sudden fire phenomenon, electric steam boiler electric heating stove is turned into intact. From the beginning of our getting shorter winter, winter heating equipment and medium-sized it seems more and more useless up.
There are many reasons after what factors led to a long period of aging gas-fired function of the boiler in use, gas boiler may appear the phenomenon of aging, this phenomenon, so we should always its maintenance and repair. Some parts of the gas boiler is very susceptible to corrosion, since these parts are long-term immersion in water, where there is water and the residual air after contact with susceptible to corrosion. Here we have for how to prevent gas boiler corrosion to analyze parts of boiler corrosion often occurs, to facilitate better precautions. First, superheater boiler vertical bends place is a place very prone to corrosion. Because the device is a long soak in the water, if water is not cleared in time of severe corrosion occurs where the surface in contact with the head play. There boiler equipment reheaters is the same and elbow are immersed in water fitting part, on the causes of corrosion and elbow are the same. Then place a part of the phenomenon of boiler economizer corrosion will occur, the speed of corrosion occurring in, if in the production of high temperature boiler has been in the work environment at the entrance is prone to corrosion in the production of relatively slow if it is discontinued after corrosion rate is not the same. Gas-fired boiler in one of the many devices and large-scale production units and other places are essential in the production and life, for use of the product is very important, people in general are specialized in boiler operation for many years boiler personnel. Correct and effective use of the product will give us a great deal of production and living convenience and productivity benefits, but if you take illegal operation or maintenance of the normal use of the device, it will cause a failure occurs during use of the device, serious anti fitments explosion caused casualties and property.
