Procedure liquid level auma boilers china boost? Boiler boosting steps are as follows: 1 when the pressure was raised to 0.05; when 0.1MPa, rinsing drum water level gauge. 2. When the pressure was raised to 0.15; 0.2MPa time, closing the drum door air, dehumidifiers hydrophobic door header. 3. When the pressure was raised to 0.25; 0.3MPa when, sequentially lower header sewage water wall door, note drum water level, the boiler feed water should be closed drum, economizer inlet to the recirculation door. 4. When the pressure was raised to 0.3MPa, the notification instrument (h) flushing pipe tables, the contact main steam turbine door open doors steam heating pipe, when the pressure was raised to 0.6; when 0.7MPa, the main valve fully open close the bypass valve. 5. When the pressure was raised to 1MPa, thermal notification into water gauge. 6. When the pressure rose when 2MPa, steady pressure to the boiler conduct a comprehensive inspection found irregularities should be stopped boost, until the fault is cleared, continue to step-up, pressure increased to 2.4MPa, sewage regularly turn. 7. When the pressure rose to 3; when 3.4MPa, rinse Water Level Indicator, notification chemical laboratory quality soft drinks, and equipment to conduct a comprehensive inspection. Boiler and steam conditions

Boiler cleaning chemical liquid level auma boilers china cleaning chemical needs to pay attention to what needs to pay attention to what? One of boiler equipment smelting industry is essential, many factories were widely used, is essential to choose. Boiler in use for a long time there will be some difficult to avoid dirt, cleaning the boiler can not be less natural, but also can effectively protect the stability of the boiler. What precautions chemical cleaning boiler is? What are the main programs are clean? First, do a good job cleaning the dirt analysis if the boiler must first analyze boiler dirt, dirt element according to the required cleaning solvent will be different. Recommended by the manufacturer should be cleaned prior analysis of impurities, and process the chemical drugs in accordance with the actual situation, to ensure that the cleaning effect of the boiler, the boiler to reduce corrosion. Second, choose Select boiler cleaning method of cleaning method is also more important, you can choose to stop cleaning, you can choose not stop cleaning, these arrangements will take into account the amount of drugs and cleaning time. In the actual cleaning, to consider the overall situation, boiler cleaning according to the situation and response control dose, to ensure that the cleaning effect, if found substandard cleaning, should be re-formulated cleaning solution. So you pass the test and then rinse with water. Third, to protect the boiler cleaning process must not only pay attention to the boiler, the boiler protection requirements are very high. Generally, after cleaning dirt, to pre-passivation film, after all, because there are a lot of metal parts exposed After evaporation, rust, corrosion easily, in order to have a good protective, membrane must be a pre-cleaning agent , its surface can be formed pro film. Film, to enhance the overall rust resistance, help to improve the lives of help.
