Factor 2, the condensing west bangal boiler rate, which has been developed for several years, has been very diversified in type and brand, and there are some differences between different types of boiler in shape structure and internal design mode. Therefore, different design methods will affect the service life of condensing boilers to a certain extent, not only in the later stage of operation, users may also affect the service life of boilers.
One of the important parts of the west bangal boiler rate - comprising a unitary structure drum boilers and boiler auxiliaries two parts. In the boiler body, the two most important parts of a drum and furnace. We have previously explained before the hearth, and today we take a look at the drum it. And the natural circulation drum is repeatedly forced circulation boiler receiving feedwater to the economizer, the coupling cycle and supplying saturated steam superheater cylindrical vessel. Simplified drum made from high quality steel plate, is one of the heaviest components of the boiler. Its main function is storage, a water separation, to exclude the water pan and brine sludge in operation, avoiding pot containing a high concentration of salt water and impurities entering with the steam superheater and a steam turbine. Internal drum means comprises a moisture separator and a steam cleaning apparatus, water distribution pipes, sewage and dosing equipment. Wherein the effect of soda is separated from the water wall by means of saturated steam and water to leave, and to minimize the steam carried fine water droplets. Low pressure boiler used as a crude flap and slit baffle separating element; above except pressure in the boiler is widely used for various types of rough separation cyclone, but also with blinds, steel mesh plate or the like are vapor further separation. The drum is also equipped with water gauges, safety valves and other monitoring and protection facilities. In use, the drum often go through thermal balance test, the time to consider the actual benefits of the boiler room, not only depends on the boiler thermal efficiency, energy meter and the auxiliary boiler also consumed. Fuel per unit mass or unit volume of complete combustion, calculated according to the chemical reaction called the theoretical air quantity of air required. In order to have more opportunities to the fuel in contact with oxygen in the furnace combustion, the actual amount of air into the furnace is always greater than the theoretical air amount. While air can be reduced into a multi incomplete combustion heat loss, but the heat losses will increase, also exacerbate corrosion of sulfur oxides and nitrogen oxides generated. We should therefore seek to improve combustion technology, as small as possible in order for the excess air ratio in the furnace so that complete combustion. Times atmospheric pollutants are oxides of dust, sulfur and nitrogen contained in the flue gas of the drum, which can achieve emissions targets Protection index when a predetermined number of times to unpurified. These substances emissions control combustion pretreatment, improved combustion techniques, dust removal, desulfurization and denitration. By means of a high chimney stack can reduce the concentration of pollutants in the atmosphere of the area. Future development will further improve boiler thermal efficiency of boilers and power plants, increase operational flexibility and level of automation of the boiler unit, improve the operational reliability of the boiler unit and auxiliary equipment, which are inseparable from the drum.
The latest was informed Tongling Municipal People's Government issued the "Notice on Tongling City to win the Battle of Blue Sky embodiment", as follows.
First, deepen industrial pollution control
Continuing to promote a comprehensive industrial pollution discharge standards, increase penalties and excessive joint disciplinary efforts, not discharge standards of the enterprise to suspend for rectification according to law. Implementation covering all stationary sources of emissions permits enterprise system, before the end of 2020 to complete the trade provisions of the license issued discharge permit management directory.
Carry iron and steel, cement, nonferrous metals, thermal power, coking, casting and other key industries and ports, shipping, coal-fired boilers fugitive emissions investigation, the establishment of management accounting, before the end of 2019 to complete the material (including waste) transportation, handling, storage, transfer and process fugitive emissions such as in-depth treatment.
Second, the continued implementation of the total coal consumption control, strict implementation of coal consumption reduction instead. By 2020 the city's coal consumption control in less than 13 million tons of coal accounts for the proportion of total energy consumption to decline further. Strict implementation of new coal projects coal reduction instead. Added support for the power industry outside of iron and steel, chemicals, nonferrous metals and other industries coal projects, the implementation of coal consumption reduction of 1.5 times alternatives. Increased focus on bulk coal remediation efforts. High-pollution fuel combustion zone ban bulk coal sales all clear.
Third, the implementation of the "coal to gas" and "electricity instead of coal." Strengthening the capacity of natural gas supply security, promote glazed tiles, casting and other industries natural gas instead of coal gasification project, orderly implementation of coal-fired facilities from coal to gas. Combined with regional and industry energy characteristics, and actively promote the implementation of "electricity instead of coal" in the field of industrial production, transportation, agricultural production, living and so on.
Fourth, continue to strengthen the supervision of the boiler. Consolidate the results of rectification of small coal-fired boiler, make sure the rebound does not occur, a citywide ban on new 35 tons of steam per hour and coal-fired boilers. Increase efforts to eliminate small coal-fired boilers. Dynamically updated list management coal-fired boiler, built-up area City 35 tons of steam per hour coal-fired boilers by the end of 2019 total phase-out or implementation of clean energy alternatives; retention of six chemical companies 2 130 tons of steam per hour of coal-fired boilers to complete all energy saving and ultra-low emissions transformation.
Fifth, strengthen the bulk coal governance. Strictly implement the "Interim Measures for commercial coal quality management" (National Development and Reform Commission Order No. 16) and technical standards for coal-fired boilers, in-depth implementation of bulk coal remediation crucial action, and strictly implement the ban on burning areas prohibit the use of high-polluting coal for fuel measures. To strengthen the management and control of coal-fired coal. Ongoing monthly coal quality sampling, and promote enterprises to increase coal-fired coal reform efforts.
Oil-fired west bangal boiler rate pressure determines the operation: oil-fired boiler is ready for operation in the cold state, the oil boiler system to understand whether the failure to adjust the fuel oil system to determine the pressure, and therefore should be done before boiler ignition oil system determining the fuel pressure work, verify oil boiler system is normal, piping, valves for leaks. Procedure: (1) to the tank opens pipeline way valve, into the fuel oil pipelines; (2) start the pump, pump outlet opening regulating valve, hydraulic pressure within the passage rises pipeline; (3) when the hydraulic pressure is raised to the operating pressure, slow open return pipe of the pump or the regulating valve is adjusted to maintain the operating pressure oil passage pipeline; (4) stop the pump; wait ignition. These are the oil-fired boiler pressure determines the operational processes hope for your help. Ventilation operation flow of oil-fired boilerFree Chat
