Careful treatment of common problems in the operation of the gas hot water boiler gas hot water boiler water shortage in many, water is one of them. Gas hot water boiler water hazards great, not only damage the normal operation of the boiler, can also cause explosions and other serious accidents, the personnel so as a fireman if detected early water shortages gas hot water boiler of this can be avoided class accidents. When the gas boiler water level has fallen below the required minimum level, but the water meter can still see the water level is slightly dry; when the water level gauge water level not seen as a serious water shortage. The dry gas water boiler performance is the first gas boiler drum water level is lower than a predetermined normal level; and low level alarms, alarm sound, signal light; superheated steam temperature increases; normal feedwater flow is not less than the steam flow; exhaust gas temperature rises. Due to the absence of water gas boiler may occur during operation, and boiler water might cause some harm. If you can discover the lack of water in the boiler gas boiler operation, we can take steps in advance to reduce the damage to the boiler water shortage caused by the gas hot water boiler, ensure the normal operation of a gas hot water boiler.
The problems in 20t h packaged steam boiler operation and the start-up of magnetic driven centrifugal pump will encounter many problems, among which the main problems are low temperature corrosion, slow exhaust speed, steam and water supply pipe damage and so on. The low temperature corrosion occurred on the low temperature heating surface of steam boiler has several main points: chemical corrosion and electrochemical corrosion. These two kinds of corrosion occur basically on the wall at lower temperature than the acid dew point. Ash deposition on the heated surface of evaporation can sometimes accelerate corrosion. The reasons for the slow exhaust rate are as follows: outlet filter core obstruction; too small cross-sectional area or long pipeline of piping; filter mesh blocking at the inlet end; reverse stop The valve won't open. Solutions to this type of problem: replace the outlet filter core, replace the larger cross-sectional line, or shorten the distance of the line; clean the filter and install an air filter at the inlet; check the spring of the reverse stop valve. In addition, steam boiler is easy to appear steam, water supply pipe damage phenomenon: when the pipe leak slightly, make noise, insulation layer wet or leakage steam, dripping water. When the pipe blasting, make a significant noise, and spray steam, water. The change of steam or feed water flow rate is abnormal, the blasting site decreases before the flow meter, and after the flow meter, the flow rate increases. A drop in steam pressure or feed water pressure. When feeding jellyfish tube blasting In 2000, the water level of the operating furnace dropped. The main causes of these phenomena are: steam pipe overtemperature operation, creep expansion beyond the standard or running time too long, metal strength reduced. Steam pipe heating pipe is not sufficient, resulting in serious water shock. The poor quality of water supply results in corrosion of pipe wall. The local scour of the water supply pipe causes the wall of the pipe to be scrubbed. Abnormal operation of the water supply system, excessive pressure fluctuations, water shock or vibration. Bad installation, manufacture, material and welding. The solution is: if the water supply pipeline leakage is slight, can maintain boiler feed water, and does not expand the fault quickly, can maintain short-term operation, put into the spare boiler as soon as possible, if the fault is added Drama, a direct threat to the safety of personal or equipment, should stop the furnace. If the water supply pipe blasting, we should try to detach the faulty pipe section from the system as soon as possible, and if it cannot be unlined and unable to maintain the drum water level, the furnace should also be shut down. If the steam pipe leakage is mild and does not enlarge the fault quickly, it can be maintained for a short period of time and put into the spare boiler as soon as possible. If the failure aggravates, it should be shut down if the failure directly threatens the safety of the person or equipment. If the boiler steam pipe blasting, unable to supply steam or direct threat to the safety of persons and equipment, should also stop the furnace. In the case of steam pipe blasting, an attempt should be made to unlist the faulty pipe segment from the system as soon as possible.
Subsequently, the Secretary-General Wang Jiao Ling line with the company's quality control staff had a discussion on the case of the reform of administrative licensing review of the existing boiler model in the country, how to promote the development of high quality assessment boiler, with the assessment of how businesses, trade associations and work promoting industry innovation and innovation to lead the development of what the expectations and demands, boiler regulations and technical specifications and implementation issues recommendations related issues exist in the process conducted in-depth exchanges and discussions, and Lu, president of the company's quality management staff made a lot of valuable Suggest. Wang Jiao Ling Secretary-General spoke highly of the technical aspects of the advantages of fast Boiler green energy and green development, and other fast-outstanding contributions boiler industry group to promote environmental protection and efficient process affirmed.
Hot water boiler structure which in the end, whether production or life, hot water boiler is we who need to use long-term, and that they now Xiao Bian gave you tell us about the structure of the relevant hot water boiler. A blower: blower air outlet of a filter is placed, after absorbing the air into the blower when the burner used to carry out flame adjustment. Second, the water pump: mainly from the second step into the flue gas pumping water softener collector, thereby absorbing energy of the hot water boiler flue gas emissions of warm water once. Third, the system of gas: natural gas containing access, burners, gas management system. Fourth, the protection valve: placing a certain value, exceeds the preset value active relief. Five more hot water boiler control and management systems, and other components of these structures is certainly a hot water boiler, if produced on the way, poor water quality rules boiler operation, is to keep from the furnace, must pay more attention. On the way produced, hot water boilers to regular maintenance, and maintenance process of careful records only careful use of maintenance to keep before they can increase productivity deeper level, not only to grasp the negative results occur.
