China BNTET Industrial Asphalt Mixing Plant Burner
Industrial asphalt mixing plant burners are also called asphalt equipment burners, drying heating burners in the asphalt industry, etc.
The burners of the asphalt mixing plant produced by our China BNTET can use gas, oil, pulverized coal, etc. as combustion materials. At the same time, we also customize the production of coal-coal-fuel dual-purpose asphalt mixing plant burners and gas-fuel dual-purpose burners according to customer needs. Wait.
As a key component of stone drying and heating, the burner has attracted wide attention from users. In the current market with a wide variety of fuels, different quality standards, and complex fuel sources, whether the burner can work well is the most basic requirement of the majority of users, so how to adjust it to the best condition? The following major issues should be paid attention to in daily inspection and maintenance~
A pressure regulating valve
Regularly check the fuel pressure regulating valve or pressure reducing valve to determine whether the surface of the lock nut on the adjustable bolt is clean and removable. If the surface of the screw or nut is dirty or rusted, the regulating valve needs to be repaired or replaced.
Check the oil pump regularly to determine whether the sealing device is intact and the internal pressure is stable, and replace the damaged or leaking sealing device. When using hot oil, check that all oil pipes are well insulated.
The filter installed between the oil tank and the oil pump must be cleaned regularly and checked for excessive wear, to ensure that the fuel reaches the oil pump smoothly from the oil tank, and to reduce the possibility of potential component failure; the "Y" type filter on the burner must Frequent cleaning, especially when heavy oil or residual oil is used, can prevent blockage of the injector and valve; when working, check the pressure gauge on the burner to see if it is within the normal range.
For burners that require compressed air, check the pressure device to see if the required pressure is generated in the burner, and clean all filters on the supply line and check for leaks in the line.
Check whether the inlet protection device on the combustion and atomizing air blower is properly installed, and whether the fan shell is not damaged or leaking; observe the operation of the blades, and adjust the blades to eliminate the noise or vibration; for the blower driven by the pulley, Lubricate the bearings and tighten the belt regularly to ensure that the blower can generate rated pressure; clean and lubricate the air valve connection to see if the operation is smooth, and replace the accessories when there is an obstacle; determine whether the air pressure meets the working requirements, and the air pressure is too low It will cause backfire and cause the guide plate at the front of the drum and the material plate in the combustion zone to overheat. Too high wind pressure will cause excessive current, and the cloth bag will have too high temperature or even scorch.
The fuel injector should be cleaned regularly and check the spark gap of the ignition electrode (about 3mm).
Always clean the flame detector (electric eye) to determine whether the location is installed correctly, the temperature is appropriate, incorrect location and high temperature will cause the photoelectric signal to be unstable or even cut off the fire.
