How does the boiler work? Where to check before going to work? How to check how to change shifts? Seek details. The actual operation of the boiler will not be tested in a few days.

Safety operation procedures for oil-fired boilers

First, the fireman must be able to operate the boiler registered by the quality and technical supervision department. Second, the fireman who operates independently must hold the fireman's operation certificate, and you meet the requirements of operating furnace type and category. Three, before the boiler ignition, the boiler body, combustion fairy and other auxiliary machines, all accessories, valves, water supply and oil supply system circuits and electronic control departments should be inspected to confirm that they are normal. Four, open the exhaust valve, to the pot water (available drainage method to check the water level control, alarm system is working properly) water level slightly lower than the normal level. 5. Manually start the fan to purge the furnace, set the control system to the "automatic" position, then press the "start" switch, and the boiler will stop temporarily according to the specified procedure: purging-ignition-combustion (big fire or small fire). If there is something wrong with the ignition program, you can continue the manual fan purging, and then you can restart the ignition. If the third ignition is unsuccessful, the ignition and oil supply must be stopped, and the ignition can be restarted only after the cause is found out and the fault is eliminated. Six, when the pressure in the pot rises to slightly greater than atmospheric pressure, the air valve can be closed when there is steam. Seven, in the process of boiler booster, according to the requirements of the regulations to do a good job of inspection and operation, confirm the normal rear can be used for steam or boiler stop. Eight, after normal operation, should often adjust the oil supply, gas supply and water supply (except automatic boiler), keep the water level and wind pressure stable, to meet the needs of the load, to ensure the steam supply. Nine, every hour in the operation should be a patrol inspection, and recorded in accordance with the provisions, signature confirmation. Ten, each shift should flush the water level gauge and sewage once, exhaust test of safety valve, pressure gauge flushing trap pipe and safety protection device calibration should be carried out as required, and truthfully fill in the record and sign the name. Eleven, normal boiler stop oil supply first, then stop gas supply, keep the water level higher than the normal water level. 12. In case of any of the following circumstances, the boiler should be stopped urgently: 1, the water level drops below the lower limit without stopping the fire, and the water will be supplied automatically; 2. Increase the water supply and take other measures, but the water level continues to decline; 3. When the water level exceeds the highest visible water level (full of water), the water level cannot be seen after the water is discharged; 4, feed water pump failure or water supply system failure, unable to feed water to the boiler; 5, water level gauge, safety valve and pressure regulator all failure; 6, set in the steam space pressure gauge all failure; 7, boiler parts are damaged, endangering the safety of operators; 8. The combustion equipment is damaged, the furnace wall collapses or the boiler frame burns red. , seriously threatening the safe operation of the boiler; 9. Other abnormal conditions endanger the safe operation of the boiler.

Boiler displacement system

Succession must be carried out by both parties, and the successor is not on duty. Successors shall not leave their posts without leave and shall not report to their superiors. The successor shall arrive at the post 15 minutes in advance, check the equipment and environmental sanitation, and make good preparations for the succession; 30 minutes before the handover, the handover personnel should check the equipment and clean the boiler room to prepare for the handover. Successors must achieve "five exchanges" and "five non-exchanges". 1, "five intersections" means that the boiler temperature, pressure and water level are normal; Safety accessories, alarms, automatic interlocking protection devices and instruments are sensitive and reliable; Boiler body is normal; All auxiliary accessories are normal; The combustion system is operating normally and the fuel reserve is sufficient; The boiler room is clean and sanitary. 2, "five don't pay" means: firefighters who don't drink; Don't give it to a seriously ill fireman; When the successor is not on duty, it will not be handed over to other non-certified firefighters; Don't move when dealing with accidents; Boiler automatic protection device, abnormal temperature, pressure, water level and combustion. Before or during the succession, the succession personnel shall be responsible for handling the accident, and after the succession, the successor shall handle the accident. After carefully verifying the relevant information item by item, both parties shall sign the handover book and complete the handover.
