Water hammer accident steam boiler for paper machinery plant factory 1, the boiler water hammer phenomenon ⑴ issued in steam boilers and pipes at a certain rhythm of percussion, sometimes loud sound, accompanied by strong vibration or water pipes steam pipes. ⑵ gauge pointer swings back and forth, consistent with the frequency of the vibration noise. When water hammer ⑶ severe, may lead to the respective connecting members, such as flanges, weld cracking, breakage of the valve. 2, the steam treatment ⑴ water hammer reduction steam supply pipe, main steam valve is closed if necessary. ⑵ Open hydrophobic superheater header pipe and the steam trap on. ⑶ drum level is too high, the sewage should be appropriate to maintain the normal water level. ⑷ strengthen water treatment work to ensure water supply and boiler water quality, prevent priming. After ⑸ water hammer arrestor, pipes and pipe rack to check, status, etc. of the flange, again without damage to a heating pipe for the steam supply. 3, the process water pipe water hammer ⑴ open air valve on the water pipe exclusion of air or steam. ⑵ enable alternate water supply pipe to the boiler feed water continues. If there is no backup line, take appropriate measures to deal with the fault processing pipeline. ⑶ check the feed pump and the water supply valve, if the problem timely maintenance. ⑷ to maintain water temperature balance. 1 accident heating surface deformation, deformation of the heating surface modification phenomenon ⑴ waterwall tubes can be seen from the door or the door to see the fire, when accompanied by water, can see the red curved waterwall tubes. ⑵ horizontal combustion furnace of the boiler, can be seen from the observation hole furnace wall to the fire front side of the deformation. 2, the reason of the heating surface modification ⑴ severe water boiler, the boiler water heating surface has to be cooled thermally deformed. ⑵ bad design structure. The local circulation flow rate is too low, stagnation, that the wall temperature exceeds the allowable temperature deformation. ⑶ installation error, so that the pressure receiving member is not free to expand. ⑷ substandard water quality, scale thicker, too much water residue.

50MW CFB boiler for paper machinery plant factory in Begumpet can be divided into the power plant CFB boiler,CFB steam boiler and CFB hot water boiler.The combustion chamber and the swirl separator of this equipment are made up of membrane water-cooling wall and the vortex separator is located in the upper of combustion chamber.

Note that the components steam boiler for paper machinery plant factorys operating matters when required to do the normal operation of the steam boiler: the normal water level in the boiler, steam pressure stability, keep clean the boiler, do shift work. Compliance with post responsibility system, strengthen the monitoring of various mechanical equipment and instrumentation. Ensure safe and reliable, to prevent accidents fireman should summarize the experience on a regular basis, and constantly improve the operational level. 1, water requirements: Gas-fired steam boiler feed water needs to be treated, the water supply should be in line with GB1576-85 "low-pressure boiler water quality standards." 2, the pot water level: always pay attention to the pot water level changes, so as to maintain the normal water level in the range of ± 30 mm, shall not exceed the highest or lowest level of the water in the water table generally slightly shaking phenomenon, such as the water still not moving, there may be blockage of the water table should be washed immediately. 3, water table: class table at least once flush water, the water level to maintain regular table glass clean, clear water to ensure accurate and reliable, such as found in glass washer water leakage when tightening the packing. The glass blurred, or can not see clear water line, although still did not effectively flush and should be replaced. Each boiler is equipped with two water table, if one of the discovery of the damage should be repaired in time, such as two simultaneous damage, immediately temporary shutdown until a water table back to normal in order to continue operation. 4, steam boiler water supply equipment: (1) All feed pumps are normal, testing should be driving at the time of shift change, if the fault repaired immediately. (2) boiler feed pumps to take water as continuous as possible, control the pump outlet valve steady. The economizer outlet water temperature should be below the maximum saturation temperature at the operating pressure 40 ℃, exceeds a predetermined temperature, with the recirculation tank to adjust the temperature of the pipe, to ensure that no damage to the economizer, and found economizer of the enclosure between litter does not seal and leakage (available candle fire near the test) embedded application asbestos rope tight. 5, steam boiler steam pressure: always pay attention to changes in pressure, as far as possible to maintain a stable pressure pot, the air pressure must not allow more than the maximum allowable working pressure. 6, pressure gauge: Syphons class should be washed once normal viewing gauge, pressure gauge found damaged, repaired or replaced immediately shutdown. To ensure the gauge, should be checked every year, such as the readings are less than ± 2.5% should be repaired or replaced. 7, the safety valve Note: a safety valve is normal, in order to prevent the valve disc and seat valve sticking regularly lifting handle is pulled, as the exhaust gas test, every 2-4 weeks should Court once elevated pressure, Experimental verification to act as an exhaust safety valve. 8, steam boiler blowdown valve: sewage regularly (once per shift).

It is understood that the main purpose of this research group is to study the production and operation of special equipment safety in our province, our city as a leader in the field of industrial and special equipment production areas of well-known companies has been the concern of the research group. After the tour, the research group said it would I recommend the best practices for future sample safe production, operation and management of special equipment, I also hope that the company's future and make greater achievements and contributions in the field.
