Condensing low nitrogen pressure boilers are widely used in various civil and commercial places, such as compound villas and commercial hotels. Its operation is convenient, using plc controller, configuration level is higher, only touch screen button can be used to control the whole operation of the boiler, so the use of this kind of boiler after the liberation of manpower, but also can reduce the cost of manpower care. So what are the advantages of condensing low nitrogen pressure boilers?
1. long service life. The condensing low nitrogen pressure boiler can be used in all kinds of environments, and it can also be used in the north of China. It has the function of anti-freezing protection, when the water in the boiler is lower than the set value, it can automatically run and heat, and automatically stop when the water temperature matches the agreed temperature, so it can protect the equipment itself and its auxiliary equipment. 2. The anticorrosive pressure boiler is not only scientifically designed, but also optimizes the operation of each system. It can not only prevent low temperature, corrosion, but also avoid the cold impact on the wall of the furnace, so its durability is strong and its service life is longer.
2. the use of safety (overheating, water shortage alarm) this pressure boiler design has taken full account of the use of safety issues, set up a number of safety gateways. It has the function of overtemperature alarm, that is, when the water temperature is super high, it will automatically stop heating, and carry on the overtemperature alarm, only need manual reset after the fault is completely relieved; It also has water shortage protection function, can automatically stop when water is short and alarm, prevent dry burning.
3. high thermal efficiency (full use of energy, energy saving) the domestic professional pressure boiler has a larger heating surface, its heat transfer efficiency is high, can maximize the enhancement of heat transfer effect. In addition, the effective outer protective layer of the pressure-bearing boiler is good, the glass cotton is used to ensure the temperature is constant, and the heat loss of the boiler is relatively small to prevent a large amount of heat dissipation, which can make full use of energy and realize high efficiency and energy saving.
Common steam seller 1t atmospheric pressure boiler overpressure incident handling process, the phenomenon (1) steam boiler overpressure sharp increase in steam pressure, exceeds the allowable working pressure gauge pointer over the "red line" safety valve after the pressure is still elevated. (2) the operation of the device is the interlock overpressure protection, should send overpressure alarm signal, stops the air blowing, the wind, coal. (3) steam temperature and steam flow rate reduction increases. 2, to treat boiler overpressure (1) weakened rapidly burning, manually open the valve or bleed valve. (2) increase the water supply, while the lower reinforcing blowdown drum (It should be noted at this time to maintain the normal water level of the boiler), in order to reduce the temperature of the boiler water, thereby reducing the pressure in the boiler drum. (3) as a safety valve malfunction or all of the pressure gauge damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When endanger the safe operation of (4) Boiler excessive pressure, blood pressure should take measures, but too fast buck is strictly prohibited. (5) boiler overpressure eliminate serious, to the boiler furnace internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified.
1, high thermal efficiency, cheaper fuel
Recently, Beihai City, Guangxi Province, issued a notice of Beihai City in Spring 2019, the comprehensive management of tackling air pollution control action program (hereinafter referred to as "Notice"), mainly for the further implement the State Council "to win the Battle of Blue Sky three-year action plan" " Guangxi tackling air pollution control three-year operational plan (2018-2020 years) "and" Guangxi 2019 spring tackling air pollution control comprehensive management action plan "to complete the Beihai tackling air pollution control tasks and achieve the 2019 goal of improving the quality of atmospheric environment.
First, the key tasks
1, and comprehensive utilization of straw Jinshao special action. County area to develop and implement straw Jinshao work program, refinement department, streets, towns, villages regulatory responsibility, the implementation of "fixed, regular, fixed people, will be responsible for" management and control, establish full coverage, no dead ends grid of the regulatory system, full use of the overhead video, satellite remote sensing, unmanned aerial vehicles inspections, straw burning a variety of means to closely monitor the information grid monitoring platform. Strengthen the inspection of law enforcement inspection, severely crack down on open burning of straw behavior. Increase efforts to promote comprehensive utilization technology of straw, conditional county incentives to take subsidies. Focus on sugarcane crop leaf prohibiting the work, in accordance with the principle of territorial management, the development of sugar cane leaves prohibiting management program, to strengthen the unified management, unified utilization, unified treatment and disposal. Municipal Agricultural Bureau, the Municipal Office of the sugar industry to strengthen guidance and support for the comprehensive development of the use of sugar cane leaves, the full implementation of mechanized harvesting of sugarcane, sugar cane fields and comprehensive utilization of straw has broken.
2, urban dust comprehensive management of special operations. The urban dust control content into the focus of supervision and improve the system of dust control mechanisms, the establishment of the construction site with information technology platform construction, water conservancy projects, the implementation of dynamic site inventory management. Supervise the implementation of the site around the site enclosure, stockpiling cover, wet earth excavation work, the main road hardening, cleaning out the vehicle, sediment transport vehicles sealed "six percent", temporarily unable to start construction land should be covered. The construction site dust pollution prevention and control into the "civilized construction" category management, dust control costs are included in the project cost; according to the law will not be in place of harmful dust management information into the construction market credit management system, in serious cases, be included in the construction market players " blacklist". Rinse vigorously promote road sweeping mechanized operations, improve road mechanized cleaning of urban built-up area. Sediment transport, coal, ore, gravel and other transportation vehicle is not confined to do, strictly punished according to law.
3, industrial enterprises air pollution comprehensive management of special operations. According to Beihai City "scattered pollution" inventory accounting, to further improve that standard and rectification requirements, classification of promoting the "messy dirty" business regulation, focusing on remediation of the city and the surrounding "messy dirty" business. Strengthen the coal-fired boilers (including biomass boilers) and brick, ceramics and other industries industrial furnaces supervision, strengthen law enforcement. Encryption of iron and steel, building materials, nonferrous metals, thermal power, cement, brick, calcium carbonate and other business materials (waste) storage, handling, crushing, transportation and other aspects of the inspection frequency of inspections, strict implementation of consecutive daily penalties, limited production shutdown and other means strictly according to law penalties for environmental violations. Focus sessions focused their attention on the process of pollution, thermal power, steel, cement, bricks, ceramics, wood processing, sugar high emission enterprises, especially in built-up urban area of business, and strictly control the total amount of air pollutant emissions.
