Using a hot water boiler safely is indeed a complex process. Let me outline the key points to help you quickly grasp the essentials:
Pre-Operation Preparation and Inspection
Personnel and Qualifications:Operators must undergo professional training and be familiar with the boiler's structure, working principles, and safe operating procedures.
Equipment Inspection:
Comprehensive Inspection:Before starting, a detailed inspection of the boiler body, pipes, valves, control system, and safety accessories (such as safety valves, pressure gauges, and water level gauges) must be conducted to ensure they are in good working order.
Water Level and Pressure:Confirm that the water level is within the normal range (usually not lower than 1/3 and not exceeding 2/3 of the water level gauge), and check the accuracy of the pressure gauge and temperature gauge.
System Inspection:Check that the fuel supply system, water treatment system, and discharge system are functioning properly.
Environmental Preparation:The boiler room should be well-ventilated, free of flammable and explosive materials, and the floor should be dry and clean.
Safe Operation During Use
Strictly Adhere to Procedures:Perform ignition, heating, operation, and sewage discharge operations according to the operating procedures. Unauthorized parameter adjustments or maintenance are strictly prohibited.
Monitor Key Parameters:
Water Level:Must be maintained within the safe range. Excessively low or high water levels may lead to accidents.
Pressure:Closely monitor pressure changes to ensure the pressure does not exceed the maximum allowable operating pressure.
Temperature:Control the outlet and return water temperatures within the set range to avoid overheating.
Daily Maintenance:
Sewage Discharge:Perform sewage discharge regularly to remove water residue and impurities, maintaining water quality.
Flushing:Regularly flush water level gauges, pressure gauges, and other meters to prevent blockages that could cause misjudgments.
Inspection:Conduct regular inspections during operation to check for leaks, air leaks, abnormal noises, abnormal vibrations, or overheating.
Safety Device Management:Ensure safety valves, pressure gauges, water level gauges, overpressure/overtemperature protection, and flameout protection devices are sensitive and reliable, and calibrate them regularly.
Emergency Handling
Emergency Shutdown Conditions: The boiler should be shut down immediately in the following situations:
Water level is too low or too high; continued operation will endanger safety.
Pressure exceeds permissible values; safety valve malfunctions.
All circulating water pumps fail.
Damage to boiler components, threatening personal safety.
Damage to combustion equipment; furnace walls turning red-hot, etc., posing a serious threat.
Emergency Operations: Immediately stop fuel supply; if necessary, use wet ash to suppress the fire; if the water level is too low, do not add water to the boiler; promptly report the incident and contact professional personnel for assistance.
