WNS 8000 kg h boiler 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,
Fire fighting methods inventory 8000 kg h boiler in the boiler use, if a fire phenomenon, you know how to deal with it? Today, Xiao Bian teach you the recipe. When coal is poor or low load, it may be administered less number, to maintain a high pulverized coal concentration, but can not chipping operation or asymmetric operation. Load is less than 170MW, should remain A, B powder layer to stable operation, when any failure to a powder, should be administered stable combustion, the failure to the powder to be put into operation, combustion stability, and then exit the gun run . Adjustment of the amount of the low-load air supply, to maintain the oxygen 4-5%, and adjust the opening degree of the auxiliary windshield. If it is a bad case of fire, may be appropriate to increase the primary air temperature, wind speed reduces time, but not overshoot the spark plugs burned once or blocked ducts. When the job should be strictly periodic system and to reduce powder powder switching system, dust bunker normal position at least 2.5 meters, so that a stable working state bunker, at each adjusting shutter powder to powder, the powder as far as possible amount consistent and stable, no spark plugs to prevent dust and to dust gravity caused by combustion fluctuations. Should maintain acceptable fineness of pulverized coal, according to chemical analysis, after adjusting the test plate to open Classifier, coal is poor or low load, it may be appropriate to increase the fineness of pulverized coal, in order to facilitate combustion. Maintain normal milling system, powder separator shall not clogging the tertiary air pinkish large deterioration in combustion. Furnace can eliminate air leakage and air leakage milling system, all view of the fire without plugging holes, play Giocondo, etc. should be tightly closed. Value of the long should keep abreast of the situation of coal and coal quality fuel, combustion instability occurs when, such as when a fault powder, coal mutation, the differential signal changes drum is too large, the oil should immediately cast coal combustion stability and taking samples for analysis. High load, the premise of ensuring steam temperature, combustion can be appropriately adjusted to prevent the shift of the center of the flame, so that the furnace exit gas temperature rise, caused by coking. Operator adjusting the main steam temperature may be employed with positive pagoda wind run, the central flame stabilizer. Should be a bellows pressure control as a basis for wind speed, in time to observe the duct pressure and temperature, the premise of ensuring primary air duct is not blocked, a bellows pressure should not exceed 4000Pa.
In recent years, Ningbo municipal government attaches great importance to environmental protection, air pollution prevention and control work to strengthen the organization and leadership, the establishment of a multi-sectoral collaboration to air quality at the core of the atmospheric environment management systems. And introduced a new quality of atmospheric environment deadline for compliance plan, as follows.
Strict implementation of total coal consumption control, to further optimize energy consumption structure, strive to 2020, coal consumption accounts for the proportion of primary energy consumption control in about 40% of coal consumption is not higher than 2011 levels, and completely cut coal province issued the task .
Strengthen management work focused on coal-fired projects, continue to promote the elimination of the transformation of small coal-fired boilers. 2019, phasing out 10 steam tons / hour of coal-fired boilers and, in 2020, the county level and above urban area basically eliminated tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities; basically eliminated the city's 10 -35 steam t / h coal-fired boiler; 35 t steam / hour and more polluting fuels and ultra-low emissions energy boilers complete transformation.
Strengthening coal quality control, within the city limits the use of ash> 16%, sulfur> 1% low-quality coal, fuel encourage high value, low sulfur, low ash blending works. 2019, the establishment of the city's coal regular testing, sampling tests system. In 2020, the city's clean coal utilization rate of 90%.
Increase natural gas use, and actively promote major infrastructure construction official website of natural gas, LNG receiving station and other utilization of natural gas, natural gas Daly improve utilization levels.
Enhance the energy efficiency of industrial enterprises. Actively promote advanced energy conservation projects integrated coal demonstration projects, large-scale generating units coal consumption reached the advanced level of the same type of unit.
Development of central heating, central heating project to optimize the layout, promote industrial parks focused on central heating. Focus on industry gathering area, industrial park development of cogeneration, and encourage qualified development of thermoelectric cooling area for the triple. Further improve the matching of heating pipe network, construction of efficient, fast heat pipe network. 300,000 kilowatts and above cogeneration power plant 15 kilometers behind the small coal-fired boilers and coal-fired thermoelectric heating within a radius of all closed down integration.
Boiler design efficiency in the engineer design phase, and in general, the actual operation and the initial design thermal efficiency are similar. For example, oil and gas furnace efficiency is greater than 92%, and circulating fluidized bed boiler efficiency is usually higher than 88%. However, boiler efficiency is not fixed. If your equipment is operating at less than design efficiency, then measures can be taken to improve boiler thermal efficiency.Free Chat
