Ms. Jiang Lianju quality system under warranty division led to ASME certification were careful overall planning work to develop a detailed plan of the evidence, and careful organization departments to participate in the work of the various stages of implementation.
Problems of industrial boiler water quality testing process industrial boiler water quality testing process there is present in the presence of water testing boiler problem during industrial Question 1, water scaling problems of industrial boiler during operation, the key indicators are mainly water and alkalinity water hardness. Boiler water alkalinity is scale. Industrial boiler water quality testing process in the presence of water scaling problems for the efficiency of the boiler operation has an important influence. The reason scale problems mainly due during boiler operation, some units and related personnel for the importance of the work of inadequate water treatment, water treatment work thus relatively neglected. At the same time, understanding industrial boilers is also one of the important reasons of scale problems. 2, boiler industrial boiler corrosion problems during operation, that the environment is very bad, there are a lot of alkaline substances and acids. The presence of these substances are boiler would cause adverse effects. Currently, some chemical companies into the production process, the materials that are used in a certain corrosive, which would cause corrosion of the boiler to a large extent, thus affecting the results of its operations. In addition, industrial processes, the agents used, the ratio unreasonable or arbitrary ratio is also an important reason leading to the boiler corrosion. In addition, improper cleaning and protection of the boiler is also an important cause of corrosion problems. 3, water treatment equipment problems With the rapid development of modern industry, water treatment devices have gradually been widely introduced into the market. Currently, in the market, the quality of the water treatment plant equipment is uneven, and thus difficult to play a role in the application. At the same time, water treatment equipment in the application process, some enterprises failed to give due importance to its relationship with water quality requirements, leading to difficult to play effective in actual operation. In addition, when using the water treatment plant, did not do the appropriate acceptance and implementation of the appropriate software is not enough and so on, also contributed to the water treatment plant is difficult to play important pragmatic reasons. 4, boiler maintenance problems in the field of modern industry, industrial boilers industrial production is an important key device, thereby enhancing the maintenance of the boiler also very necessary. However, industrial boilers in actual use, maintenance has been neglected status. This is mainly due to the seasonal nature boiler will exist in the application process, and thus in the maintenance process, should be maintained in accordance with the actual situation. But in the actual work, this work due to human factors and institutional factors and many other factors, it is difficult to smoothly, thereby affecting the operation of the boiler. In summer, for example, due to the presence of water vapor and oxygen gas, which is more prone to water film, not subjected to treatment once bound to increase the corrosion rate of the boiler.
Boiler heat boiler thermodynamic inequality unevenness is generated in the same group of heating surface, the phenomenon of uneven heat load. Thermal variation caused by the structural characteristics of both, can also be caused by operating conditions. The uneven distribution of the phenomenon of uneven speed and smoke along the width of the smoke flue temperature; serpentine planar heating surface unevenness caused by uneven pitch fumes or corridor; heating surface fouling, slagging furnace flame deflection center; run to adjust the flame so bad skewed, down, raise, etc., will cause uneven heat. (L) reaches a rated steam parameters and ensure stable operation. (2) to ensure stable ignition, combustion central appropriate, uniform distribution of the flame, the device does not burn, to avoid fouling and coke. (3) the boiler and crew safe operation under the most economical conditions.
Price price gas boiler gas boiler: gas boiler during operation can be carried out from two aspects of preparation and inspection work before the start of the run. Prepared before the start: a normal condition of gas pressure check to see if the valve leaks, and a valve switch is in place. 2. To test whether the gas alarm system to work properly, it is necessary to test whether the fan can be started. 3. In order to check the water softening system, the softening agent should be in operation, the water level of the tank should be in a normal state. 4. Check the boiler, the switching valve decontamination, to see whether it is working properly. 5. Circulation pump outlet valve closed, to start the circulation pump, slowly open the outlet valve, the outlet pressure is adjusted to 0.3-0.35MPa, back pressure to 0.2-0.25MPa. Check operation: 1. Open the power boiler, the boiler normal firing condition monitoring, checking and flame status of each component of the operation sound. 2. boiler heating situation can not be ignored, the transformation of large and small control if normal. 4. Return water temperature recorded for each circuit, the water supply valve to adjust the return water temperature consistent. Recorded once every two hours each circuit water pressure and temperature. 5. After checking the boiler pressure, temperature display abnormal situation, should stop to check the boiler. 6. Check the gas flow and gas pressure stability is within the normal range, to determine whether there is clogging of the filter. 7. Check whether the pressure pump abnormal noise and other anomalies.
