Gas steam boiler maintenance

1、 Maintenance method 1 The boiler feed water must be treated as qualified, which is an important matter to extend the boiler life and ensure the operation safety 2 The feed water temperature shall be close to the furnace body temperature by more than 20 ℃ 3 The low water level cut-off device must be checked, maintained and cleaned regularly The royal banquet steam pot reminds the water level controller to clean at least once a month, and the water level gauge to wash at least once a day The water level of the water level gauge shall be at the water level; the water level after flushing shall not be lower than the safe water level If the water level is not clean at one time, it can be rinsed several times, but it must be rinsed at the water level 4 It is necessary to conduct regular blowdown operation at least once a day (every shift) After blowdown, check whether the blowdown valve leaks due to the influence of pollutants; if so, it must be eliminated 5 When the boiler is shut down without maintaining the steam pressure, the steam space of the boiler will generate negative pressure and retain air, so the main steam valve shall be opened first when the boiler is fired again 6 After the soot is accumulated in the smoke pipe, the temperature of the exhaust gas will rise, which will reduce the efficiency of the boiler and increase the fuel consumption Therefore, the front and rear door covers shall be opened regularly to brush or blow the soot in the smoke pipe 2 Shutdown maintenance and anti-corrosion 1 After the shutdown of the energy-saving steam furnace, it must be maintained to prevent corrosion in the boiler 2 Short term maintenance The wet maintenance method can be adopted, that is, after the boiler is shut down, the boiler water shall be filled up and the air shall be discharged completely 3 Long term maintenance Dry maintenance method can be adopted, that is, drain the boiler water after shutdown, open the lower hand hole, blow dry the water in the boiler, put desiccant through the lower hand hole, and replace it regularly, and check and replace it once a month at the beginning, and once every three months later However, it should be noted that all desiccants must be taken out before the boiler is put into operation III monitoring and maintenance 1 During the operation of the boiler, the equipment shall be inspected once every hour, focusing on the operation of the boiler safety parts and rotating equipment 2 The inspection, test, regular operation and other project periods of boiler equipment shall be specified and loaded on site in the form of icons 3 The operating personnel shall fill in the records in time according to the inspection conditions 4 The site must be kept clean and free of sundries, ash, ponding and oil dirt
