As an important industrial thermal equipment, the safe operation of gas steam boilers is directly related to production efficiency and personnel safety. To ensure stable operation of the equipment and prevent accidents, the following are key usage precautions, covering operating standards, maintenance points, and emergency response.
1、 Preparation work before operation
1. Personnel qualifications: Operators must undergo professional training and hold certificates to work, familiar with boiler performance and safety knowledge; Non professionals are strictly prohibited from operating equipment.
2. Equipment inspection: Before starting, it is necessary to confirm that the boiler and safety accessories (such as pressure gauges and safety valves) have passed inspection and are within their validity period; Check the natural gas pressure, filter ventilation, and operation status of softened water equipment to ensure that the water quality meets the standards.
3. Environmental assessment: The boiler room should maintain good ventilation and install gas leak alarm devices; The operation area has sufficient lighting, no accumulation of debris, and eliminates fire hazards.
2、 Safety regulations during operation
1. Ignition and Boosting: Strictly follow the ignition sequence, first blow the furnace to eliminate residual gas; Regularly discharge pollutants during the boosting process and flush the water level gauge to ensure that the water level is clearly visible.
2. Parameter monitoring: Real time monitoring of boiler water indicators (such as alkalinity 6-26mmol/L, pH 10-12) and steam pressure to avoid overload operation; Immediately shut down the furnace for inspection upon discovering any abnormalities.
3. Protection device: Ensure that safety systems such as explosion-proof doors, flameout protection, and pressure interlocking are functioning properly; Unauthorized removal or modification of control programs is prohibited.
3、 Daily maintenance and upkeep
1. Regular cleaning: Clean gas pipeline filters, photoelectric sensors, and other components to prevent blockages from affecting combustion efficiency; Check the lubrication of mechanical components to reduce wear and tear.
2. Attachment verification: flush the water level gauge for each shift, verify the safety valve and pressure gauge; Stop repairing immediately if water leakage or damage is found.
3. Scale treatment: Regularly discharge and soften the water supply to avoid scaling and overheating in the furnace; Keep the boiler pipes unobstructed to prevent ash deposition.
4、 Shutdown and emergency response
1. Normal shutdown: Close the natural gas valve and power supply, and check the tightness of the drain valve after the pressure drops to a safe range; Ensure that the water level is at a high level.
2. Emergency shutdown: In case of malfunction, quickly cut off the gas source and air supply, and weaken the induced draft; If necessary, exhaust the gas inside the furnace and strictly prohibit watering the furnace; Open the furnace door to cool down and wait for the temperature to drop below 70 ℃ before draining.
3. Accident prevention: Operators need to regularly practice emergency procedures. In case of overpressure or leakage, they should immediately activate the emergency disconnect device and report it.
5、 Key points of long-term management
1. Training and awareness: Continuously conduct safety training to enhance the emergency response capabilities of operators; Emphasize the principle of "safety first" and eliminate illegal operations.
2. Environmental maintenance: The boiler room should be clean and dry, with unobstructed ventilation openings; Regularly check the insulation parts to prevent burns or electric shock.
3. Technical update: Pay attention to equipment upgrades, such as adopting modular design to simplify maintenance processes, but traditional boilers still need to strictly follow regulations.
By implementing the above measures, the operational risks of gas steam boilers can be significantly reduced, ensuring production safety and efficiency. Operators need to remain vigilant at all times, internalize norms into daily habits, and jointly build a strong safety defense line.
