According to Anhui Province to work in the 2018 year-end summary of the province, in 2018, Anhui Province, built-up area exceeding 35 cities steam tons / hour or less industrial coal-fired low pressure hydrogen boiler for heatings as well as glass, ceramic industry, industrial kilns clean energy alternative to work. Complete 97 sets of clean energy alternatives, completion rate of 76.4%, exceeding the annual target of 50% substitution tasks.
It is reported that Anhui start from the following aspects to strengthen the control and management of coal-fired boilers, is over-done.
First, strengthen research, Mozhun the truth.
1, carry out key research, went to Hefei, Bengbu, Chuzhou development of industrial coal-fired boilers, kilns clean energy alternative research work, the front line, replace understand the business progress, issues and rationalization proposals exist.
2, a diagnostic investigation, issued "regarding the development of cities and built-up areas 35 steam tons / hour boiler and industrial enterprises and the glass and ceramics industry, industrial kilns investigation work" and collect aggregate and cross-checking data to improve municipalities investigation; Third, learn practice field, go to Tianjin, Hebei research study "coal clear" action and glass industry furnace clean energy alternative to work, learn from the successful experience of leading regions. Grasp the province's boiler, furnace conditions first-hand data, be aware of the difficulties of enterprises, clear focus and difficult work.
Second, a clear mandate to strengthen the scheduling.
Issued a "built-up area of Anhui Province cities 35 tons of steam per hour of coal-fired industrial boilers as well as glass, ceramics industry, clean energy alternative to coal-fired furnaces work plan", based on clear objectives, tasks, scope and duration of the transformation node, proposed work requirements. And issued a "35 tons of steam and industrial coal-fired boilers and the notification submitted on a regular basis municipalities built-up area per hour, glass, ceramics industry, coal-fired kilns clean energy alternative to progress information", and held a forum, a monthly tracking scheduling progress, and urge municipalities in accordance with the program of work, and steadily promote the implementation of alternative work schedule.
Third, innovative initiatives to promote accurate.
For enterprises in the implementation of coal-fired boilers, furnaces clean energy alternative technology transformation encountered financial problems, the implementation of precise advance.
1, the organization held a provincial industrial boilers clean energy alternative technical equipment special promotion, targeted Recommend energy-efficient air units, heat pumps integrated device source, environmentally friendly low-emission of nitrogen gas boiler and a number of boiler clean energy alternative to new technology and equipment, docking platform to build both supply and demand.
2, a clean energy alternative to key projects in 2019 included green manufacturing project-oriented investment program to enhance the enthusiasm of enterprise transformation.
The transformation of the new low pressure hydrogen boiler for heating Necessity gas boiler water treatment in the course of the boiler, the boiler lot longer due to the use of long or serious aging parts, no transformation is necessary, it will consider the new boiler, following small new the need for boiler water treatment gas on a simple analysis. Water quality will directly affect the boiler during operation late boiler thermal efficiency, security, operating life, etc., so treatment is very necessary. In the process of boiler water treatment, basically to pay attention to two points, one boiler water treatment equipment selection, and second, the standard boiler water treatment. Under normal circumstances, because the user considers to price factors, while ignoring considerations of quality water treatment equipment. Resulting in the boiler feed water still contains a lot of impurities in the untreated water treatment effect can not reach the required standard, thereby enabling the emergence of boiler corrosion, fouling and other phenomenon during the late run, the small affected the operation of the boiler thermal efficiency, it is very easy to cause a boiler accident affect the safe operation of the boiler and operating life. Thus in the process of transformation in the boiler, the new gas-fired boiler during water treatment, in accordance with the provisions must be strictly water treatment equipment selection, water quality testing and so on, were considered in the long-term significance.
Textile enterprises purchase low pressure hydrogen boiler for heating model for how to determine the factors that affect this question is that there a lot. First, look at the size of the enterprise, as well as local textile enterprises which use steam boiler, which is about the amount of steam required fee, there is the running time, the expansion of the scale of the late, need to be considered. In short, depending on the size of the business, its specialty (air spinning, clothing, etc.) as well as its usefulness. If the size of the textile workers of about 1,000 people, with 1 ton boiler to meet production.
Three kinds of food plants Comparison of three combustion low pressure hydrogen boiler for heating combustion boiler plant food three kinds of comparative combustion boiler plant food Comparative 1, the advantages of premix combustion mode] [Multi transfer method, heat radiator progress toward a uniform intensity; burning rate , reaches the optimum temperature and thoroughness; increase the radiating area, adjust the intensity of the radiation unit 1300 degrees Celsius combustion, low NOx occurs, but also easy to recover the latent heat of vaporization. [Disadvantage] premixed combustion ratio required accurate fast combustion rate, combustion efficiency of radiant heat transfer uniformity abundant high flame temperature below 1200 deg.] C, all complete combustion and low NOx flue gas temperature occurs, condenses, heat recovery, high efficiency. 2, partially premixed combustion [advantage] burning speed, intensity and thoroughness stable combustion of some progress, although the downsizing, but sex is still stable. [Disadvantage] obtained secondary co-oxidant for an open furnace, heat loss occurs in incomplete combustion emissions and NOx concentration is still high.[email protected]
