Note the fuel gas-fired boiler fuel gas pressure when the talk about fire boiler shutdown in accordance with the fuel (electricity, oil, gas) can be divided into electric industrial environment-friendly steam boiler, steam boiler fuel, gas steam boiler three kinds; in accordance with the constitution can be divided into vertical steam boilers, horizontal steam boiler, steam boiler, mostly small and medium sized single, double the return of the vertical structure, large steam boilers and more horizontal structure of three return. The following is a pressure Cautions fire boiler 1 shutdown, shutdown pressure fire more than 6h, main steam valve should be closed after the pressure of the fire over time, open trap superheater outlet header of the superheater to cool. After closing the main steam valve, such as pressure goes up, and can be used at the same time into the sewage Boiler Feed down method. When the recovery boiler operation, subject to step-up and step 2 protection, thermal shutdown during the press pot still steam pressure, it must still pay attention to monitoring, and to allow the boiler to maintain the water level 3, with a cast iron gas boiler province, in after stopping the boiler feed water, the shutter should be closed save flue gas, furnace bypass channel open flap or in the circulation pipe, stopping the gas temperature exceeds a predetermined value within the province 4, the pressure during the shutdown should be appropriate fire sewage, furnace exclude precipitation Care was taken after pressure fire shutdown should not immediately stop the operation of the circulating pump, the network should continue circulating water circulating in the system for some time, when the boiler outlet water temperature dropped to 50oC with the following, in order to stop the operation of the circulating pump
If there is damage in the supposed gas-fired? Detailed inspection is important, as the key oil regulation. According to the conditions and time management, gas-fired, people can effectively damage inspection program. The application of oil, people strictly control the particle size of coal and dolomite. Should strictly control the particle size of bed material. Should be addressed furnace waste. To be able to solve the waste furnace after discharge. Natural gas boiler should be installed in areas where the application of calories, easy to install. Heating pipe can not be too long. It should have a good cable jacket. Water piping for an output from moderate to tail skew. Water resources to be equipped with a pressure regulating valve. As sewage gas, natural gas boiler chimney should widen to the outside, a heating furnace entrance width 1.5 to 2M. If you want to reduce the harm to the water wall tube can be appropriately regulate air pressure and wind speed and reasonable to reduce damage to the water wall. Inspection time is generally standby shutdown or shutdown condition. To check top head comprising the furnace wall is damaged, leakage of the furnace airtight and smoke. In the damaged condition requires immediate repair and welding, in order to ensure that no problem in the operation of industrial environment-friendly steam boilers. Typically, before the ignition of gas-fired, fossil fuels must be added the charge in the combustion chamber, fossil energy and raw material-circulating bed material and gas in the wind, the strength and intensity of the flow down completely integrated. Bottom wind equipment, up for the core area. Exercise our powers in a ring outside the region along the furnace wall water swimming down, thus increasing the waiting time of coal particles in the furnace. Mineral particles, many of the ash and soot particles with a lot of fly ash, this resulting in rapid deterioration of the waterwall tubes continuously, so that damage to the wall thickness becomes soft, resulting in damage.
WNS4-1.25-YQ fuel gas-fired boiler WNS4-1.25-YQ fuel gas-fired boiler WNS4-1.25-YQ fuel gas-fired boiler can be widely used in hospitals, schools, textile mills, garment factories, supermarkets, garment factories and other units.
