15 MW vacuum boiler gas hot water
Run the vacuum hot water 15 mw vacuum boiler hot water reliability depends on these three areas: 1. In order to ensure the degree of vacuum inside the boiler, at the factory to create a rigorous inspection, the quasi gas leak detection, to ensure a sealed boiler tank production process. To maintain the degree of vacuum, and to prevent the event, the plant is equipped with a standard suction pump. When the vacuum tank hot water boiler body, the heat medium water is heated to 90 ℃, according to the degree of vacuum exhaust pump automatic operation of the tank, not only the air out of the tank, also the presence of dissolved oxygen in water to remove the heat medium, to keep certain negative pressure, produced inside the tank will not corrode. 2. Water is a heat medium by a special manufacturing plant impurity, oxygen, water softening treatment, in the production of disposable infusion, can be recycled at runtime, without generally no special filling. I visited the plant in the design of the user survey, a Shanghai Electrical Machinery Plant, 87 years put into operation a vacuum hot water boiler, use a decade overheated media never raise water, which can still work normally. 3. A heat exchanger in the boiler with special requirements, using SUS444 stainless steel tube, which requires a special process during tube processing. The tubing is difficult to furring, high heat transfer efficiency, will not rust, the heat exchange tubes in a more than ordinary quality restrictions, flow rate. Steam boiler fuel by category descriptions
How discharge of sewage vacuum 15 mw vacuum boiler hot water (1) inside the drain valve is opened; (2) Slowly open the outer discharge valve, for discharging sewage and heating pipes; (3) off and on repeatedly outer drain valve, a buffer scale pot so trying to scale discharge ; (4) bonded on the inner blowdown valve, the water in the discharge between the two discharge valves; (5) engaged on the outside of the drain valve, complete discharge of sewage.
This entalphy shown turbine outlet conditions 0,5 bar 85,4 C or 0,2 bar 85 C (vacuum) water must be cooled up to 50 C (inlet of 15 mw vacuum boiler hot water).
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 15 mw vacuum boiler hot waters 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.
