9) other unusual circumstances endanger the safe operation of the boiler; gas-fired emergency manual shutdown should focus on preventing the accident and concrete steps "manual" → "small fire" → "shutdown."
Water tube boiler structure and characteristics (the horizontal double boiler drum water): double horizontal tube boiler drum mainly by the horizontal drum, convection bank, the waterwall tubes, and headers and other downcomer pressure components. A front portion of the boiler furnace, the furnace water wall are arranged four weeks; on the drum located at the rear lower horizontal furnace, connected by a bend between the two drum pipes. Chain grate combustion equipment to use, some of Pulverized or roaster, with superheater, economizer and air preheater. After entering the furnace by the high temperature flue gas flowing through the superheater convection pass over, and then down to an upwardly rising S-shaped transverse convection bank erosion, and then down to the upper folding back pass, the economizer, the pre-air heat, by the induced draft fan, chimney discharged into the atmosphere. Evaporation boilers generally less than 20 tons / hour (t / h), the working pressure is less than 2.5 megapascals (MPa).
Since Prime Minister Li Keqiang in the "five" proposed "Blue Sky Wars," after the strategic plan states that China provinces and cities are doing to improve environmental protection. Jilin Provincial People's Government recently issued a "Jilin Province to implement the winning Blue Sky Battle three-year action plan to implement the program," coal-fired units will conduct a comprehensive reform.
Jilin Provincial People's Government recently issued a "Jilin Province to implement the winning Blue Sky Battle three-year action plan to implement the program" (hereinafter referred to as the "Program") said that before the end of 2018, the province's 300,000 kilowatts or more coal-fired units completed ultra-low emissions transformation. Continue to promote the 200,000 kilowatts class ultra low emission coal-fired unit renovation project, before the end of 2019, ultra-low emissions and strive to transform the province's total unit capacity of thermal power capacity of more than 75%.
"Program" also proposed to complete the transformation of ultra-low emission electricity generation units appropriate to increase the number of hours. Vigorously for shutting down environmental protection, energy consumption, safety and other 300,000 kilowatts coal-fired units of non-compliance. Coal-fired generating units to increase the technological transformation efforts, speed up the heating pipe network construction, fully release and improve the heating capacity, eliminate coal heating boiler pipe network coverage and the range of loose coal. In areas do not have the cogeneration district heating conditions, the existing multiple small coal-fired boilers, alternative construction of large-capacity coal-fired boilers in accordance with the principle of equal volume. Before the end of 2020, within a 15 km radius of 300,000 kilowatts of heating and cogeneration power plant above range, in the case of cogeneration heating load to meet the heating needs, in addition to the need to retain the peaking boiler, coal-fired heating boilers and small coal-fired thermoelectric behind all closed down integration.
In addition, long-term control of total coal consumption in accordance with planning requirements, Jilin Province, to continue to reduce the amount of coal consumption, coal consumption in new coal projects to implement alternative reduction, by 2020, reduce the proportion of coal accounting for the province's total primary energy consumption to 63% the following. According to focus on the use of coal and clean use of principles, focusing on reduction of non-power coal, increase the proportion of electricity from coal, the state-assigned task is completed, the province's electricity by 2020, the proportion of thermal coal coal consumption reached more than 55%.
In the future, the province will carry out a comprehensive environmental aspects of governance, economic development and environmental protection go hand in hand.
With the increasingly broad application of condensing boilers, its technical level, energy conservation, environmental protection advantages are increasingly prominent, users in order to increase the efficiency of enterprises and better energy conservation, effectively reduce emissions, But many enterprises do not know how to choose condensing boiler manufacturers. In order to better ensure boiler quality, users need to select manufacturers from the following aspects of comprehensive evaluation:
1. When selecting the condensing boiler manufacturer, users should first know the technical situation of the manufacturer, and see if the boiler has advanced domestic production technology, such as whether the frequency conversion combustion technology is used to fully burn the combustion material. Whether the boiler is ultra-low carbon fully premixed combustion technology to improve combustion efficiency, whether the boiler uses high-efficiency full condensation heat transfer technology to improve the efficiency, and so on, only the boiler manufacturers with advanced technology, can produce ultra-high cost-effective, Products of good quality and performance.
2. The size of R & D team and the level of R & D directly affect the development of condensing boiler manufacturers, so users should first have a strong R & D team when choosing condensing boiler manufacturers. In addition, powerful manufacturers will be equipped with a sound R & D team mechanism, from R & D production, testing and installation to later debugging and other specialized personnel to complete the work. Users can learn about the R & D team level and team mechanism of the factory through online survey or on-the-spot study.
3. Condensing boiler manufacturers with good service systems usually provide perfect services, and this is also a point that users need to pay attention to when selecting manufacturers, that is, users from planning to purchase equipment to consult manufacturers about equipment questions such as condensing boilers of what specifications are used. How to install, the manufacturer will arrange professional pre-sales specialist and user docking, when the information is finished, customer service personnel will recommend the appropriate type of equipment according to the needs of the user. After the completion of the sales, if the user has questions about the product or failure, you can contact the manufacturer customer service department in time.
2020-5-4·Already from the beginning wrong water treatment in a steam boiler, steam generator or high pressure hot water boiler will lead to a negative shift in total cost of ownership (TCO). This will cause increased costs and major problems for you and your business. Some of these problems are:
