To stop running after the boiler flameout, why fans need to continue ventilation 5min? Since the flame shutdown process, since the furnace temperature is lowered, the combustion unstable, so that incomplete combustion of fuel increases, the fuel remaining in the furnace and the flue waste heat of the furnace under heating, then combustion will produce a direct threat to the safety of boiler equipment. So turn off the boiler, ventilation fans continue for some time to take away the fuel in the furnace, but ventilation time not too long, otherwise due to the large amount of cold air directly into the furnace, make the furnace, flues and various heating surface is rapidly cooled contraction, resulting in damage. Therefore, the boiler flame, the ventilation fans continue 5min stopped, and then close the shutter smoke duct, so that the furnace and the flue is in the closed state, and also continues to monitor the flue gas temperature to prevent the pump do not re-combustibles combustion.
In the last meeting on April 16, the hard efforts of audits and company officials of president Mr. Lu Haigang couplet review group to pay thanked rigorous review and couplets group work style, professional skills to express my sincere admiration. Ms. Jiang Lianju warranty division said it will continue to improve the ASME quality control system to ensure produce sophisticated products comply with ASME standards. According to ASME certification process, after the on-site audit, the company will obtain certification and stamp issued within 20 working days, this will be the development of our company in the history of another "milestone" event.
Which is good combined 650 bhp steam boiler price plant Nehe current domestic steam boiler manufacturer, according to different evaporation, the case has strengths steam boiler alone. The questioner does not know whether the normative standards of reasoning steam boiler in question covers what. In general, if you want to you can be correctly selected the company's steam boiler, a bunch of criteria listed below need to understand: First, the thermal efficiency of steam boiler Second, a steam boiler steam velocity Third, identify the amount of evaporation four steam boilers, steam boilers more than a bunch of standard category, it is to buy a steam boiler is the most common non-compliance, which should most seriously consider non-compliance, from a bunch of these criteria, whether there is a problem can be summed up a set of steam boilers effect, obviously, steam boiler election process, to find the best for your company, cost-effective steam boiler is only the most critical.
wns operation of the boiler which measures gas boiler gas boiler is basically a device that can be seen in many large factories or businesses. Of course, such a device, in actual operation, in fact, has its own operating standards. On the current situation, they have more protection measures while running. Then when it is running, gas-fired boiler operational measures WNS What? (1) After a series of gas boiler maintenance, operation should be substantially in accordance with the requirements during operation. There will be a lot of protection, even if they need to determine the importance of the protection of the entire work. (2) during ignition of a gas boiler, there may be more or less regulatory requirements, such as to meet the requirements of the fuel. However, the fuel pressure in the process of evaporation or mist, more or less meet certain requirements stroke, to some extent, the entire inspection returned to the normal state. They prohibit short signal fire, but also in the entire flow is greater than the introduction of a single gun when 0.65 kg per second. (3) When the ignition gas boiler, the temperature must be noted that all the furnace, the temperature inside the main view, the entire main steam pressure deviation will be obvious during ascent. Or if the voice does not rise, you must check the ignition of the fuel tank immediately. Further, if it is found throughout the fuel into the furnace and there is no fire, the boiler will be tightly closed.Free Chat
