The purpose of oxygen removal from feed water in industrial boilers is to reduce oxygen corrosion and bubble formation within the boiler, ensuring the safety and normal operation of the boiler and piping systems. The main methods of oxygen removal include: 1. Mechanical Oxygen Removal: This involves physically removing oxygen from the water. Common mechanical oxygen removal equipment includes deaerators and degassers. Deaerators achieve this by spraying water into a thin film, utilizing the difference in gas solubility to remove oxygen from the water. Degassers, on the other hand, spray water into tiny droplets, again using the difference in gas solubility to remove oxygen. 2. Thermal Oxygen Removal: This method utilizes the property that oxygen solubility decreases with increasing temperature by heating the water body. Common thermal oxygen removal equipment includes deaerators and deaeration pots. The deaeration pot releases oxygen from the water by heating it to saturation temperature. The deaerator heats the water, using the decreased solubility of oxygen to remove it. 3. Chemical Oxygen Removal: This involves adding chemicals to react with the oxygen in the water, thereby removing it. Common chemical oxygen removal agents include salts and reductants. Chemical oxygen removal is often used in high-pressure boiler systems and can effectively remove oxygen from the water. The choice of oxygen removal method and its application depend on the specific boiler system and water quality. In practical applications, a combination of different oxygen removal methods is often used to achieve the desired effect. The selection and operation of oxygen removal equipment should be assessed and adjusted based on actual conditions to ensure the safety and normal operation of the boiler system.

Safety requirements for steam boiler valves mainly include the following aspects: Valve Selection: Choose the appropriate type and specification of valves for steam boilers. The valves must comply with relevant standards and specifications, and possess characteristics such as high-temperature resistance, pressure resistance, and corrosion resistance. Valve Installation: The valves should be installed correctly at the corresponding positions on the steam boiler. During installation, ensure that the connections are secure and the seals are reliable to prevent leaks and loosening. Valve Operation: The operation of the valves should be convenient and flexible, and capable of accurately controlling steam flow and pressure. The handle or device should indicate the direction of opening and closing as well as the corresponding operation methods. Valve Sealing: The sealing performance of the valves is crucial. The valves should have good sealing properties to prevent steam leakage and energy loss. The sealing surface should be flat, smooth, and able to withstand high temperatures and wear. Valve Maintenance: Regularly inspect and maintain the valves to ensure their normal operation and safety performance. This includes cleaning the valves, checking the sealing surfaces, lubricating moving parts, and promptly repairing or replacing damaged components. Safety Valve: A safety valve must be installed on the steam boiler to protect the safe operation of the boiler. The safety valve must comply with relevant standards and specifications and should automatically open to release over-pressurized steam when exceeding the set pressure, preventing boiler explosions. Valve Identification: The valves should be marked with their type, specification, working pressure, and flow rate information. This aids operators in correctly identifying and operating the valves, avoiding incorrect operations and accidents. It should be noted that the above safety requirements are general guidelines; specific safety requirements must be determined based on the type, scale, and operating environment of the steam boiler. When using valves, follow relevant laws, regulations, and safety operation procedures to ensure the safe operation and effective control of the valves.

To extend the service life of steam boilers, the following measures can be taken: 1. Regular maintenance: Conduct regular maintenance on the boiler, including cleaning burners, flues, and heat exchangers, inspecting and replacing worn parts, ensuring normal operation and efficiency. 2. Water quality control: Maintain good water quality to prevent scale and corrosion from damaging the boiler. Regularly test water quality and implement corresponding treatment measures based on test results, such as descaling and supplementing missing chemicals. 3. Control combustion process: Properly manage the combustion process to ensure normal operation and efficiency of the burner. Regularly inspect the burner's operating status, adjust combustion parameters, and avoid overheating or cooling issues. 4. Regular cleaning of flues and heat exchangers: Regularly clean flues and heat exchangers to remove soot and dirt, maintain heat exchange efficiency, and prevent overheating and energy loss. 5. Regular inspection of safety devices: Regularly check the boiler's safety devices, including safety valves, pressure switches, and level controllers, to ensure normal operation and guarantee safe boiler operation. 6. Record and monitor: Record operating parameters, maintenance records, and fault conditions of the boiler, regularly monitor and analyze, and address problems promptly with appropriate measures. 7. Train operators: Ensure operators have adequate knowledge of boiler operation and maintenance, operate and maintain boilers correctly, and avoid damage caused by operation errors or improper maintenance. 8. Regular inspections and repairs: Based on the boiler's usage and manufacturer's recommendations, schedule regular major repairs and inspections, replace worn parts, and extend the boiler's service life. These measures can help extend the service life of steam boilers. However, please note that for safety and effectiveness, maintenance and repairs should be performed by qualified personnel.

Before starting the heating gas hot water boiler, the following correct procedures must be followed: - Check the gas supply system: Ensure the gas supply system is operating properly, inspect gas pipes, valves, and pressure regulators, ensuring there are no leaks or blockages in the gas supply. - Check the water system: Inspect the water circulation system of the heating system, including pumps, valves, and pipes, ensuring the waterway is clear with no leaks or blockages. - Check the electrical system: Inspect the boiler's electrical system, including power connections, controllers, and sensors, ensuring electrical equipment is functioning normally. - Check the safety devices: Inspect the boiler's safety devices, including safety valves, pressure switches, and water level controllers, ensuring they are working properly to ensure safe boiler operation. - Prepare for ignition: According to the boiler's operating instructions, prepare the tools and equipment needed for ignition, including an igniter and ignition power. - Open the gas valve: Slowly open the gas valve to ensure a steady gas supply and avoid gas surges. - Ignition start-up: Follow the boiler's operating instructions for ignition start-up. Perform the corresponding operations based on the boiler model and control system to ensure smooth ignition. - Monitor operating status: After startup, closely monitor the boiler's operating status, including combustion, water level, and pressure, ensuring normal operation with no anomalies. - Adjust parameters: Adjust the boiler's parameters as needed, including temperature, pressure, and water level, to meet the requirements of the heating system. - Regular maintenance: After startup, perform regular maintenance, including cleaning the burner, checking water level and pressure, and replacing worn parts, to ensure normal operation and safety of the boiler. - It is recommended to refer to the boiler's operation manual and manufacturer's guidelines before starting the heating gas hot water boiler to ensure correct and safe operation. If necessary, personnel can be requested for operation and maintenance.
