What are the three common 12 bars fired boiler in hospital combustion? Urban coal-fired boiler has been difficult to solve, because especially small coal-fired boilers type cluttered and more widespread particularly difficult to handle. On the one hand burning low power, on the other hand is more a waste of resources. Under the requirements of environmental protection requirements, many cities in the relevant part of the requirements necessary gas (oil) boiler retrofit or replacement of 10t / h coal-fired boilers. The transformation of the former needs to focus attention to the following questions: whether the site is useful region of central heating boiler heating of small alternative program. The useful life and corroded boiler, if the boiler by Zhengzhou fast boiler or other professional testing organization to determine the useful life of less than five years, the transformation of value is not high. Determine whether the laying of gas pipeline convenience, liquefied petroleum gas or other fuel supply and transportation issues. Comparing the cost of renovation and equipment manufacturers advantages and disadvantages, in determining the needs of the transformation plan in compliance with these principles. Selection of fuel. Under the premise of fuel sources have, the most economical natural gas pipelines, liquefied petroleum gas, followed by a final light diesel oil. Also, consider the surrounding environment from fire and explosion safety. In general, the system and the soda boiler pressure parts and preferably not modified to adhere to the original power, are demand, under conditions not substantially change the pressure member, than the original power increased by 10% to 20%. Boiler pressure parts for major changes in the program desirable. The transformation process is necessary to ensure the safety of boiler pressure parts of (mostly small commercial general pressure boilers), followed by incineration system to ensure the safety factor, the decline in the risk of explosion, fire accidents. Recognize the transformation of the planning process, in a timely manner, the environmental protection, the gas company, fire department, urban construction and timely communication with the boiler section to monitor and ensure the transformation plan can proceed smoothly. When the boiler is burning way during boiler selection will take into account an element, the following three common boiler burning approach advantages and disadvantages brief analysis cf: 1 Decentralized incineration strengths: this way is not burning premixed, but the gas nozzle mouth dispersed with each other, and then burning it. Incineration relatively simple way, as more stable as compared to the flame. Disadvantages: Due to a longer flame, it is prone to the phenomenon of incomplete burning, more carbon monoxide and nitrogen oxides will occur, it is not conducive to the use of full-fired boilers, to improve the thermal power of the boiler, and the boiler emissions standards are difficult to reach. 2. premix approaches incineration advantages: premixing air and gas, a multi-way heat radiator, to improve the strength of heat transfer. Strengths of this approach is that the burning of the burning flame is more clear, and the higher heating power. Disadvantages: incineration requires precise ratio premix burning rate is fast, uniform burning radiant heat transfer full power high flame temperature below 1200 deg.] C, all NOx completely burned and the occurrence of low flue gas temperature, condenses, good heat recovery and high power. 3. No flame burning incineration space before incineration approach uniform mixing with the gas in the gas boiler. When using this approach, in the process of incineration gas in the oxygen demand is not made in the ambient air demand, only needs to achieve instant complete incineration air mixture reaches the incineration zone. Approach in the selection of incineration, incineration demand for the advantages and disadvantages of different approaches, carried out mutatis mutandis selection, a good way is also advantageous burning boiler to reach plenty of incineration, thermal power increase, decrease the role of emissions, and therefore, it is important to choose carefully.
WNS 12 bars fired boiler in hospital burner imported or domestic brands Fortunately, on this issue, different people have different views, some people think that the domestic economy is substantial, others believe that the import is effective and energy-saving. Each has its own advantages, but it is undeniable that domestic and foreign brands burner on the strength is still a gap, because the domestic burner technology started more than foreign, naturally there are differences, the main difference lies in the following points: 1 oil and gas burners aspects of R & D capability, meaning: in Europe and the United States and other developed countries, each burner manufacturer has its own research and development test center to provide strong support, development burner technology . 2. In the low NOx combustion and low nitrogen emissions, the burner domestic enterprises has just started, the relatively low level of technology. 3. In the production and marketing of products of combustion, burner foreign manufacturers to achieve mass production of large, has a great advantage in terms of parts procurement and manufacturing cost control and market promotion. Therefore, the domestic conventional fuel burners in the market is clearly not competitive. At present, domestic burners companies to non-standard products to market breakthrough, it is difficult to form a large-scale mass production. Fang fast wns not only provide domestic gas boiler burner, also available internationally renowned burner Italy Riyadh Road (RIELLO), Decker (BALTUR), Germany Weishaupt (WEISHAUPT), United Kingdom Granville (nuway), etc., manufacturers need to configuration. 4579,
Now on the market most of the 12 bars fired boiler in hospitals to gas, oil, biomass, electricity as the main fuel, coal-fired boilers because of its harmful pollution levels gradually been changed or replaced. In general, no boiler explosion during normal operation, but if it is due to the improper operation of the ignition or operation, it may cause the furnace or tail or secondary combustion flue explosion, resulting in serious danger of impact. In this case the role of "explosion vent" is manifested when the furnace or flue trace knocking occurs, the pressure within the furnace is gradually increased, when a certain value is higher than the pressure relief device can turn on itself through the explosion vent to avoid the risk expansion to ensure the overall safety of boiler and furnace wall, more importantly, it is to protect the safety of the boiler operator. Currently there are blasting boiler membrane and two kinds of swing-proof door.
April 4, 2019 morning, Xi'an Beilin haze iron-fisted rule to organize the use of gas-fired 12 bars fired boiler in hospital unit of area businesses, held a 2019 low nitrogen gas boiler renovation work Publicizing.
The meeting mainly to accelerate the transformation of low nitrogen gas boiler Beilin, the ecological environment Beilin Branch Office investigator, neighborhood offices iron-fisted rule haze Director; area involving boiler 2019 user units, boiler enterprises, related to the monitoring unit responsible comrades total of more than 180 participants. Ecological Environment Agency Beilin Branch Comrade security level currently in Xi'an ambient air quality situation, problems and countermeasures were presented. Ecological Environment Agency celebration party strongman rule Beilin Branch Office Director haze on the transformation of relevant documents and carry out propaganda premium policy interpretation. 2018 transformation of the user units China Qiyuan Engineering Design & Research Institute Co., Comrade Yang Ann introduced to transform the experience of last year. Finally, the ecological environment Beilin Branch Bureau researcher Liu made a concluding statement:Free Chat
