Gas boiler ignition failure divided into several categories? How to deal with? With the advance of coal to gas, gas boilers have been gradually replaced by coal-fired boiler, with a high market share. But gas boiler often encounter some problems, mainly gas-fired boilers can not be said today about the firing of several reasons. 1, a boiler ignition pressure is too high or too low, the range of no ignition. Solution: Check boiler pressure, to see whether the pressure within the pressure range of the ignition of the burner, can be operated in a control cabinet. 2, the boiler water level is too low, ultra-low water level below the boilers, automatic interlocking, burner misfire. Solution: Check the boiler water level is below the low water levels if the boiler. 3, the exhaust gas temperature is too high, automatic chain protection boiler, burner does not ignite. Solution: Check the boiler flue gas temperature, smoke to see if the shutdown temperature is higher than the boiler 4, the gas inlet pressure is too low or too high, the burner is not firing. Solution: Check the burner inlet gauge to see whether the pressure composite ignition pressure boiler 5, natural gas leaks, burner does not ignite. Processing Method: General burner comes with leak detection means may be self-monitoring. 6, a gas burner commissioning and unreasonable air distribution control, auto-off after burner ignition. Processing method: the ratio of gas and air not debugging, the inlet air is too large, the firing automatic fire 7, the boiler emergency stop switch is erroneous, misfire burner (boiler is not in operation) Processing Method: General this time all the features are not method used, can be self-monitoring. 8, own fault burner, burner ignition contact rod iron, programmer failure, warning lights flashing. Approach: this time do not operate their own troubleshooting, and quickly find the right service door.
Hot water boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas dzl series coal fired hot water boiler for greenhouse (WNS4.2-1.0 / 115 / 70-YQ).
Categories Industrial boilers and boiler design standards to consider whether overload: boiler, which is the site of important products and key words, but also in terms of all of us, but also focus on learning and understanding of the object, so, based on these two points, but also to know Learn boiler, everyone is hurt, they can broaden their knowledge. So, what reason not to be taken seriously and be it! In this way, we are also capable of deriving the relevant boiler expertise. 1. industrial boilers in the boiler, which is generally divided into several? What classification criteria that have? Industrial boilers, which is a boiler, which is generally divided into two types, one is industrial steam boilers used to generate electricity or gas supply, therefore, can be vaporized to steam plant fertilizer, coal as raw material synthesized spending. Another is based on coal as fuel in industrial boilers. The type of gas, mainly used in the waste heat boiler. Industrial boilers, which can have different classification criteria. For example, by use of points, industrial boilers can be divided into two dzl series coal fired hot water boiler for greenhouses and steam boilers; according to points product performance, it can be divided into three steel industrial boilers, industrial boilers and condensing boilers in vacuo.
Gas Steam Boiler non-normal stall, a phenomenon and treatment, flame reasons: 1, the operation of the auxiliary power supply or trip interruption. 2, boiler combustion instability. 3, the load is too low, so that the load sharply mill automatic ignition energy loss or failure of combustion. 4, mutant coal, coal volatile or low calorific value. 5, the automatic combustion flame detector failure or failure caused by tripping mill. 6, or blast furnace wall tubes serious improper boiler soot-blowing operation, a large amount of water vapor into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a significant amount of fuel reduction or interruption. Or with a large amount of water in the fuel oil gun blocked too many impurities, low pressure steam or atomized. Second, the phenomenon: 1, a significant increase in furnace pressure, furnace flame monitoring flameless CRT display. See the fire no fire hole, BTG warning window MFT warning lights. 2, the unit load decrease, the steam flow drops rapidly, each segment working medium temperature, the vapor pressure decreases, the value of oxygen surge. Third, the method of treatment: 1, if the MFT tripping protection, should an emergency shutdown processing, stop the supply of fuel. 2, identify the cause flameout, and try to eliminate, to conduct a comprehensive inspection of the boiler, after confirming the device properly, can restart. How early circulating fluidized bed boiler ignition achieve the protection of reheaters? Fire causes of valve failure chemical industry regulation and Countermeasures bearing parts heat treated high boiler common defects due to low bypass the security gate and reheaters failure phenomenon and treatment of condensate pump turbine worm gear failure cause analysis and improvement measures in the pneumatic valve powder operating system instructions on how to implement.
