Fuel gas boiler maintenance
For maintenance of boiler rooms for more than two years, professional maintenance measures should be taken.
1, Safety reasons: The boiler belongs to special equipment and is a highly mechatronic product. If the inspection and maintenance are not timely, the line will be aging; the oil circuit, oil pump and oil nozzle will be blocked and worn; the gas engine valve group will not seal well, leak and stay. Under security risks.
2, energy-saving reasons: regular use of instruments for gas testing, so that combustion is sufficient and reasonable, to achieve energy-saving effects.
3, environmental reasons: the use of instrument testing, to promote emissions standards, free of pollution
Fuel gas burner maintenance
Burner operating procedures
First, the inspection of the fuel machine before commissioning has three aspects:
1. Check if the diesel is in place, the fuel line is clean and unobstructed, and the valve is open.
2. Whether there is pipeline leakage or not, the pipeline installation is reasonable.
3. Whether the oil returning oil pipeline is installed correctly, the return oil pipe is not allowed to install the valve
Second, the internal inspection of the fuel machine
1. Whether the burner of the burner is installed and the ignition electrode is adjusted.
2. Is the motor rotating in the correct direction?
3. Whether the external circuit connection meets the requirements.
4. The cold state simulation of the burner is carried out according to the line condition, and it is observed whether the various components of the equipment in operation are normal and whether the flame detection protection part is normal.
Third, the debugging of the burner
1. Check if the external diesel is in place, the pipeline is unobstructed, and the external power supply is in place.
2. Adjust the load of the burner to a small load, adjust the ignition position to a small load, turn off the large load to ignite and observe the flame condition, and adjust the servo motor or damper according to the flame condition.
3. When adjusting the fire output of the burner, it is necessary to adjust from a relatively small load to a large load according to the load condition of the heat equipment, and adjust the servo motor or the damper according to the situation.
4. Observe the flames for partial fire, insufficient flame combustion, vibration and other phenomena.
5. After the adjustment, multiple ignitions should be performed to see if the ignition is good.
Fourth, the site requirements:
1. Unrelated personnel who are involved in commissioning work are required to leave the job site.
2. It is forbidden to work in any other way (such as electric welding, gas cutting, etc.).
3. In order to ensure the personal safety of the commissioning personnel, when the burner is ignited, it should be 1 meter away from the side of the burner. When the flame is stable, the flame can be observed at the sight glass and the next step of power adjustment and other adjustments.
Fifth Precautions for commissioning and maintenance of fuel oil
1. When the secondary combustion program of the fuel burner fails continuously, it should be stopped to check whether the fuel supply system of the burner is normal, whether the circuit connection is correct, and the burner can be restarted after the fault is cancelled.
2. It is strictly forbidden to smoke, weld, cut and other illegal operations on site.
3. In the debugging work, it must be done seriously, safely and efficiently.
4. It is forbidden to use non-explosion-proof electric power tools on site.
5. Explain the safety operation precautions to the customer in detail.
6. It is required to check if the oil circuit is open before starting the machine.
7. It is recommended not to commission the fuel machine at night.
8. At the end of commissioning, the operator should be trained to use the direction of operation and establish the flow of operations if necessary.
Feature:
1. Design with three pass structure horizontal, support OEM ,absorbs the thermal expansion effectively. Corrugated furnace large diameter, large combustion space, high combustion efficiency.
2. Equipped with multiple safety protection devices, such as pressure controller, pressure transmitter, water level alarm, safety valve, etc.
3. Adopts PLC full automatic intelligent control cabinet and interlock protection program, has the protection function of water shortage, over pressure, over temperature, gas leakage, flame out, electric leakage, and phrase-lacking or overloading of motor, etc.
4. Equipped with reliable boiler auxiliaries,such as world known famous burner(Riello, Baltur, Unigas,Weishaupt,etc), international famous brand water pump(Grundfos, CNP), Siemens brand electric control elements, Fleck brand water softemner from USA, etc
5. Adopt the latest boiler technology, 100% flaw detection test, high quality, and long working life, low maintenance fee.
Flue gas emissions comply with the environmental requirements of the first-class regions of the country.
Water supply hardness: 0.03mmol / L,
Oxygen content: 0.1mg / L,
Boiler water full alkalinity: 6 ~ 24mmol / L,
PH (25 ° C): 10 ~ 12.
The soften water will promise boiler long life time .
