Because asphalt station burner specification model is very large, classification is also more diverse, must be combined with their actual needs to make a purchase, select the specification models suited to their needs, we look at the composition and structure of asphalt mixing plant burner flame requirements

Asphalt mixing plant burner structure composed of
One machine gun is a fan motor, pumps, and other chassis components are combined in one control, characterized by small size, smaller than the schedule, typically 1: 2.5, more choice of high voltage electron combustion system, a lower cost, but the quality of the fuel and environmental requirements higher. The material and diesel fuel models such optional devices, such as the German "Weishaupt" in 120t / h or less. It is split host machine gun, fan, pump group, four separate control components dividend arrangements. Characterized by large volume, output power, multi-use gas combustion system, scheduling is relatively large, typically 1: 4 to 1: 6, or even up to 1:10, low noise, fuel quality and less demanding environment. Domestic and foreign road construction work of this multi-use models, such as the British "Parker," Japan, "Tanaka" Italy "ABS". Asphalt mixing plant burner structures can be divided into an automatic control of combustion air supply system, fuel supply system, control system, a combustion system. Air supply system for a complete combustion of the fuel to be supplied to the satisfaction of oxygen, different fuels have different air flow requirements, per kg of oil required for a complete combustion of the distribution 15.7m3 / h of air at standard pressure conditions such as diesel 0. Heat value 9550Kcal / Kg complete combustion of heavy oil to be distribution 15m3 / h of air. The fuel supply system for a complete combustion of the fuel shall provide reasonable combustion space and the mixing space. Fuel delivery approaches can be divided into high-pressure and low-pressure delivery shipping. Wherein the pressure in a high pressure atomizer burners selected transport way, the pressure required is 15 ~ 28bar. Rotor selection of a low pressure atomizing burner conveying way, the pressure required is 5 ~ 8bar. Now, road construction machinery operation of the fuel supply system for multi-use high-pressure delivery approach. Road machine operation control system for use because of its specificity mechanical working conditions are selected to control the ratio of the scheduling approach the burner. Combustion system flame shape depends substantially complete combustion of the combustion system. Burner flame is not greater than the diameter of a 1.6M general requirements, relatively wide scheduling as well, usually to about 1: 6: 4 to 1. Flame diameter pose a serious coke formation on the furnace tube is too large, excessively long flames can result in excessive damage to the exhaust gas temperature dust bag, the material will also cause browning or oily feeding curtain. In my mixing station unit 2000 as an example: the drying cylinder diameter of 2.2m, a length of 7.7m, the flame is not greater than the maximum diameter of 1.5m, preferably the flame length can be scheduled in any of 2.5 ~ 4.5m.
