constitute
1. Air supply system: the function of the air supply system is to send the atmosphere with certain wind speed and breeze into the incineration chamber. The key components are: shell, fan motor, fan impeller, air gun and fire pipe, damper controller, damper baffle, cam adjusting mechanism and dispersion plate.
2. Combustion system: the effect of combustion system lies in the inclusion of combustion atmosphere and fuel, and its key components include: combustion transformer, combustion electrode, electric fire high-voltage cable.
3. Monitoring system: the function of the monitoring system is to ensure the safe and stable operation of the incinerator. Its key components include flame monitor, pressure monitor, temperature monitor, etc.
4. Fuel system: the function of fuel system is to guarantee the fuel required for incineration of incinerator. The main points are: oil pipe and discussion, oil pump, solenoid valve, nozzle, heavy oil preheater.
5. Electric control system: therefore, in the middle of instruction and containment of each system in the electric control system, it is important to master that the component is the program controller. Different incinerators are equipped with different program controllers. The most common program controllers are LFL series, LAL series, loa series and LGB series. The most important difference is the time difference of each French step.
Incinerator features
Therefore, the fuel oil incinerator is mainly composed of oil atomizer and air conditioner.
Fuel oil (diesel, heavy oil, residual oil, tar, oli oil, etc.) incineration has the characteristics of good atomization result, convenient combustion, thorough incineration, flame consolidation, strong rigidity, no coking, no infarction, long service life, etc. It can burn light oil, heavy diesel oil, heavy oil, residual oil, tar, asphalt, oli oil and other liquid fuels.
Liquid mist particles (SMD < 40 μ m) with uniform size dispersion (size dispersion index n > 2). The atomization results of kaimingyang fuel are not affected by the fuel viscosity. The size of the oil hole and the fine hole of the nozzle are large, so it is not easy to be blocked and coking. Atomization consumes less gas and energy. Flame length, flame cone angle and flame pattern can be planned according to user's request. The flame has strong rigidity and high radiation rate. Complete the cold burning of heavy residual oil. The flow adjustment range is more than 1:4. The combustion is complete, and the equilibrium fuel saving rate of burning heavy residual oil is more than 8%, and that of burning diesel oil is more than 4% (compared with the old incinerator).
Operation procedure analysis
Inspection before debugging
1. Check whether the diesel oil is in place, whether the fuel pipeline is clean and circulating, and whether the valve is opened.
2. Whether there are signs of pipeline leakage and whether the pipeline is arranged reasonably.
3. Check whether the oil inlet and return pipes are accurately arranged, and it is not allowed to place valves in the return pipes
Search inside the fuel engine
1. Whether the oil nozzle of the incinerator is installed and whether the combustion electrode is properly adjusted.
2. The deviation of motor torsion shall be accurate.
3. External circuit combination shall meet the requirements.
4. Based on the clear environment, cold simulation shall be carried out for the incinerator. During the investigation, all parts of the building shall be normal and the flame detection guard shall be unilateral normal.
Commissioning of incinerator
1. Check whether the external diesel oil is in place, whether the pipeline is in circulation, and whether the external power supply is in place.
2. Adjust the load of the incinerator to a small load, adjust the combustion status response to a small load, close the large load for combustion and investigate the flame environment, and adjust the response of the servo motor to the approximate damper based on the flame environment.
3. When adjusting the fire force of the incinerator, it is necessary to adjust the load environment of the hot building from small load to large load, and adjust the response of the environment to the servo motor damper.
4. Investigate whether there is any sign of partial fire, insufficient flame burning, touch, etc.
5. After the mediation, it is necessary to hold repeated combustion to investigate whether the combustion is superior.
Site request
1. The staff irrelevant to the commissioning work request to leave the work site.
2. No other methods of homework (such as electric welding, gas cutting, etc.) are allowed.
3. In order to ensure the personal safety of the commissioning staff, when the incinerator is burning, it should be 1 meter away from the incinerator side. When the flame is burned and consolidated, the flame can be investigated at the investigation mirror, and the next step is to focus on Mediation and other mediation.
Fuel engine debugging and after-sales attention
1. In case of secondary combustion failure of the fuel oil incinerator in succession, it shall be shut down for search and inspection. If the fuel supply system of the incinerator is normal and the circuit connection is accurate, the incinerator can be restarted only after the obstacles are eliminated.
2. Smoking, welding, cutting and other illegal operations are strictly prohibited on site.
3. In debugging, we must be serious, safe and efficient.
4. It is not allowed to use non explosion-proof electric tools on site.
5. Pay attention to safe operation to customers.
6. Before starting the machine, ask to search whether the oil circuit is opened.
7. Initiate not to conduct fuel oil engine commissioning at night.
8. At the end of commissioning, it is necessary to construct the training for operators to apply the operation bias, and establish the operation process when necessary
