9 tips for using a burner
The following points should be noted when using the burner:
1.In case of continuous failure of the secondary ignition program of the gas burner, it shall stop the machine to check whether the gas supply system of the burner is normal and whether the circuit connection is correct. Only after the fault is removed can the burner be restarted.
2.It is forbidden to strike or rub the air supply pipeline with wrench or metal rod to avoid causing static electricity or spark and causing gas explosion.
3.Smoking, welding, cutting and other illegal operations are strictly prohibited in the air supply valve set or the flange face of the pipeline.
4.It is strictly forbidden to conduct any open fire test near the pipeline and valve group and pressure regulating valve to avoid serious accidents.
5.Test whether there is fuel in the air supply line, usually with a gas low pressure meter test.
6.In the air supply pipeline, is the empty, but there are residual gas or liquid droplets on the wall, such as electrostatic spark and open fire will also cause combustion and explosion.
7.When the air supply pipeline is ventilated and the valve set is in trouble, it is necessary to remove it. First, the front front main valve of the valve set must be cut off, and then the gas in the pipeline from the main valve to the valve set should be emptied, before the disassembly and maintenance of the valve set can be carried out.
8.In debugging, gas must be serious, safe and efficient.
9.No explosion-proof electric power tools are allowed on site.
EBICO EBS... series burner is the fourth generation of cpmpact type and electronic proportional control digital burner researched and development specially for asphalt mixing plant equipment. This burner is designed according to the three major ideas of European products on safety, environmental protection and saving energy, as well as special environment and fuel requirements of China market. It is a new generation of advanced intelligent electronic proportional control machine which is launched to the market after being approved by lots of test and qualified data. This model is scientific and rational in design, compact in size, complete in structure and low in failure rate. Through the application of many new technologies, it can save 5%~12% fuel and at most about 40% electrical energy; it is an ideal product suitable for both fixed asphalt mixing plant and mobile asphalt mixing plant.
The valve set is suitable for all non-standard gas (such as coke oven gas, coal bed gas, blast furnace gas, generator gas) and large flow burners, explosion-proof and corrosion-resistant burners or multiple burners that can share the air supply valve. Each burner needs separate filters, metering and control devices.
Maintenance
The frame is fully movable; both the frame and the control system have full-open doors, so the machine can be maintained easily after moving the main frame forward and backward or opening those doors. Such quick and efficient maintenance service owes to the design experience of EBICO integration module system.
From the perspective of heat transfer calculation, the measures to reduce the smoke exhaust temperature are analyzed from the following aspects: increasing the heat exchange surface, improving the heat exchange efficiency of the heating surface, improving the heat exchange temperature difference by using a lower temperature source, and reducing the influence of corrosion on the heat exchange efficiency.As gas boiler host first meet the low nitrogen flame furnace volume and size requirements, the second host of convection heating surface is a main export in order to reduce the smoke temperature, general control in 150 ~ 250 ° C, in order to avoid the smoke temperature increases along with the flue design difficulty of heat preservation, high smoking temperature is too low will cause corrosion in furnace convection heating surface forming wall condensation, therefore, furnace domestic demand to design proper heating surface, the physical dimension more representative chamber size.Increasing the heat exchange surface should mainly consider increasing the heat exchange area of the equipment in the rear of the boiler, which is more favorable for rapidly reducing the exhaust temperature.The second is to have a lower inlet water temperature can be used for heat exchange temperature difference characteristics;Third, corrosion resistant materials can be used to improve its service life.The new structure of efficient heat exchange mainly adopts the form of staggered tube arrangement, efficient heat exchange finned tube, plate heat exchanger, etc., to increase the flue gas disturbance and contact surface, reduce the heat resistance of flue gas stratification, and improve the heat exchange efficiency of medium and flue gas.
