The purpose of deoxygenation in industrial boiler feed water is to reduce oxygen corrosion and bubble formation within the boiler, ensuring the safety and proper operation of the boiler and pipeline system. The main methods of deoxygenation include: 1. Mechanical Deoxygenation: Removing oxygen from water through physical means. Common mechanical deoxygenation equipment includes deaerators and degassers. Deaerators remove oxygen by atomizing water into a film, taking advantage of the difference in gas solubility. Degassers remove oxygen by atomizing water into tiny droplets, also utilizing the difference in gas solubility. 2. Thermal Deoxygenation: Removing oxygen from water by heating the water body, taking advantage of the property that oxygen solubility decreases with temperature. Common thermal deoxygenation equipment includes deaerating pots and deaerators. Deaerating pots release oxygen from water by heating it to saturation temperature. Deaerators remove oxygen by heating water, taking advantage of the reduced solubility of oxygen. 3. Chemical Deoxygenation: Removing oxygen from water by adding chemicals that react with it, thus removing oxygen. Common chemical deoxygenating agents include salts, reducers, etc. Chemical deoxygenation is often used in high-pressure boiler systems and can effectively remove oxygen from water. The choice of deoxygenation method depends on the specific boiler system and water quality. In practical applications, a combination of deoxygenation methods is often used to achieve the desired deoxygenation effect. The selection and operation of deoxygenation equipment should be assessed and adjusted based on actual conditions to ensure the safety and proper 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. Valves must comply with relevant standards and specifications, and possess characteristics such as high-temperature resistance, pressure resistance, and corrosion resistance. Valve Installation: Valves should be installed correctly in the corresponding position of the steam boiler. During installation, ensure the connection is secure, the seal is reliable, and leaks and loosening are prevented. Valve Operation: Valve operation should be easy, flexible, and capable of accurately controlling steam flow and pressure. The handle or device should indicate the opening and closing direction of the valve, as well as the corresponding operation method. Valve Sealing: The sealing performance of the valve is crucial. 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 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 its safe operation. The safety valve must comply with relevant standards and specifications and should automatically open when the pressure exceeds the set value, releasing over-pressurized steam to prevent boiler explosion. Valve Identification: Valves should be marked with their type, specification, working pressure, and flow rate information. This helps operators correctly identify and operate valves, avoiding incorrect operations and accidents. It should be noted that the above safety requirements are general guidelines, and specific safety requirements must be determined according to the type, scale, and operating environment of the steam boiler. When using valves, follow relevant laws, regulations, and safety operation procedures to ensure safe and effective valve operation and control.

To extend the service life of steam boilers, the following measures can be taken: - Regular Maintenance: Conduct regular maintenance on the boiler, including cleaning burners, flues, and heat exchangers, checking and replacing worn parts, to ensure normal operation and efficiency. - Water Quality Control: Maintain good boiler water quality to prevent scale and corrosion from damaging the boiler. Regularly test water quality and implement corresponding water treatment measures based on test results, such as descaling and replenishing missing chemicals. - Control Combustion Process: Reasonably control the combustion process to ensure the normal operation and efficiency of the burner. Regularly inspect the burner's working condition, adjust combustion parameters, and avoid issues like overheating or underheating. - 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. - Regular Inspection of Safety Devices: Regularly inspect the boiler's safety devices, including safety valves, pressure switches, and level controllers, to ensure proper functioning and safe operation. - Record Keeping and Monitoring: Record boiler operating parameters, maintenance records, and fault conditions, and regularly monitor and analyze them to identify and address issues promptly. - Training Operators: Ensure operators have sufficient knowledge of boiler operation and maintenance, operate and maintain the boiler correctly, and avoid damage caused by operation errors and improper maintenance. - Regular Overhauls: Based on the boiler's usage and manufacturer's recommendations, schedule regular major overhauls and inspections to replace worn-out parts and extend the boiler's service life. These measures can help extend the service life of steam boilers, but please note that for safety and effectiveness, maintenance and repairs should be performed by qualified personnel.

Prior to starting the heating gas hot water boiler, the following proper procedures must be followed: - Inspect the gas supply system: Ensure the gas supply system is operating correctly, check gas pipelines, valves, and pressure regulators, etc., to ensure 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, to ensure the waterway is clear, with no leaks or blockages. - Inspect the electrical system: Check the electrical system of the boiler, including power connections, controllers, and sensors, to ensure the electrical equipment is functioning properly. - Inspect the safety devices: Check the safety devices of the boiler, including safety valves, pressure switches, and water level controllers, to ensure they are operating correctly and ensure the safe operation of the boiler. - Prepare for ignition: According to the boiler's operating instructions, prepare the tools and equipment needed for ignition, including an igniter and ignition electricity. - 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 to perform the ignition start-up. Perform the corresponding operations according to 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, to ensure normal operation and no abnormal conditions. - Adjust parameters: Adjust the boiler's parameters according to actual needs, 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 the normal operation and safety of the boiler. - It is recommended to refer to the boiler's operating manual and manufacturer's guidance before starting the heating gas hot water boiler to ensure correct and safe operation. If necessary, personnel can be requested for operation and maintenance.
