In order to ensure safe and economic operation of the boiler, ensure the personal safety, boiler operating personnel must strictly carry out the relevant regulations and procedures of steam boiler safety technology supervision.

The Preparation of before Start oil and gas boiler:

• Internal and external inspection: confirm the boiler body, burning machine, accessory equipment in good condition; safety accessories, each valves and instrument are flexible and stayed accurate location.

• Check the line voltage reach the requirements or not, all kinds of switch is normal, start the pump, combustion engine fan, pumps and other auxiliary respectively to see operation is normal or not.

• Feed water into boiler: open the drain valve to make the water level up to the normal water level(slightly below the water level)

Begin to Operate:

• Oil and gas boiler is the program to start. Press the start button on the control ark and the combustion engine fan motor begin the programmed-start. First step is furnace purging about 2 minutes and then automatic ignition and stable combustion.

• After the ignition, the worker should adjust combustion according to the required amount of load and them boiler operates normally.

• The operator should monitor the water level change closely in the process of operation to prevent water shortage accident or filled with water accident.

Boosting Pressure:

• When the steam pressure rises to 0.05-0.1Mpa, worker should flush water gauge.

• When the steam pressure rise to 0.1-0.15Mpa, worker should flush the trap tube of pressure gauge.

• When steam pressure rises to the rated working pressure, the newly installed boiler safely valve and the relief valve after repaired should be debugging in accordance with the relevant provisions and seal. The relief valve during the validity period of maintenance should take discharge test.

Warm Tube and Make two Boilers Work Together:

• In order to prevent the steam supply producing water hammer, warm tube should be done before steam supply, it will take when steam pressure up to two-thirds of the rated pressure in common situation. The time of warm tube can be calculated according to pipe length and the ambient temperature.

• When two boilers' steam supply to the same steam mother tube must be conducted in accordance with the provision and furnace operation.

Normal Operation

Water Level:

• Boiler water level gauge should have a red line to indicate the high, medium and low water level, in the operation, water level shall not exceed the maximum safe level or below the minimum safety level.

• Water gauge should be washed at least once per class, when there is a doubt that water level is not right, the work should check at any time and as soon as possible.

• The boiler worker need to test high and low level alarm at least once a month.

Vapor Pressure:Pressure gauges shall be red line to indicate work pressure sensitively and reliably. Trap tube should be flush at least once a week.

Safety Valve:The relief valve should be seal in good condition and without leakage. Take a emission test once a week, some statistics should be recorded in the maintenance record book for reference, such as start pressure, opening pressure, back pressure and test time, participants.

Drain Contamination

• Under the guidance of the water quality test staff and according to the requirements of the boiler water quality to take 1-2 times per shift. Drainage time should not too long, generally no more than 10 minutes.

• Drainage should be taken in low load and low steam pressure, high water level. The best time is after the boiler stop. The change of water level should be monitored closely during drainage and pay attention to safety.

• When more than one boiler share a sewage, discharge at the same time is prohibited.
