Basic knowledge of burner in asphalt mixing station

Thermal conductivity oil, is GB/T 4016-1983 "Petroleum product terminology" in the "heat carrier oil" used name, the English name is heat transfer oils, used for indirect transmission of heat of a class of special oil with better thermal stability.
Because of its uniform heating, accurate temperature control, can produce high temperature under low steam pressure, good heat transfer effect, energy saving, transportation and easy operation and other characteristics, in recent years has been widely used in various occasions, and triangular core winding machine use and dosage more and more.

Asphalt mixing equipment is a kind of equipment used in highway construction, it is composed of combustion station and asphalt mixing station and other parts, in order to achieve the goal of energy saving and emission reduction, what improvements should be made from the technical aspects?

Burner as a high degree of automation of mechatronics equipment, from its realization of the function can be divided into five major systems: Air supply system, ignition system, monitoring system, fuel system, electronic control system.

Mineral type heat conduction oil is a distillation product of petroleum refining process, the main component of which varies with the composition of base oil.
It is generally a mixture of long chain alkanes and Naphthene.

Therefore, in the work of raw material matching, we need to consider the high pressure reciprocating pump in advance of these aspects of the problem, choose a reasonable matching scheme.
This will be conducive to the asphalt mixing plant construction quality improvement, of course, we must first as low as possible to collect and investigate aggregate resources, on the other hand, we also need to choose the appropriate mixing equipment model.

From the current situation of China's highway construction, in the future for a long time, asphalt mixing station will also get a great development.
This is also a result of rapid economic development.
However, we found that when the modern construction of asphalt pavement, there are more and more quality problems, therefore, we have to put forward more stringent requirements for the quality of asphalt use.

It is obvious that the production efficiency of civil asphalt mixer is smaller, so if you want to configure asphalt mixing station, you will not choose this type of product, it is only suitable for smaller projects.
The more common forms are crawl drum type asphalt mixer, diesel engine drum type asphalt mixer, climbing type Asphalt Mixing Plants mixer, lifting drum type asphalt mixer and so on.

When testing the heat conduction fluid in operation, it is found that the viscosity is not regular because of the joint influence of decomposition and polymerization. The acid value increases gradually and then decreases in the early stage of oxidation. Flash point is an important index to explain the safety of oil operation. The residual carbon has been on the rise, starting slowly, and then the numerical growth has accelerated significantly.

In addition, the energy saving and emission reduction of asphalt mixing equipment should also be from the asphalt mixture production process to start, mixed material temperature of at least 100 ℃, can use emulsified asphalt, so that you can have a good energy-saving role
>At the same time, we should also improve the working principle of mixing equipment, according to different needs to choose different mixing equipment, so that the effectiveness of the equipment can be fully utilized

>The function of the air supply system is to send a certain wind speed and wind volume to the combustion chamber, its main components are: Shell, fan motor, fan impeller, wind gun fire pipe, valve controller, valve gear plate, diffusion disk

>2, to avoid the heat conduction oil coking heat conduction oil in the operating temperature above the maximum use temperature, in the guide pipe wall will appear coking phenomenon, with the thickening of the coking layer, the guide tubing wall temperature is high and promote adhesion coking, the continuous thickening of the pipe wall temperature further improved, with the pipe wall continuous thickening heat transfer performance deterioration, at any time there may b
>Therefore, strictly control the temperature of the heat conduction oil at the outlet of the thermal carrier must not exceed the maximum use temperature, the maximum film temperature of the heat carrier should be less than the allowable oil film temperature

>and engineering asphalt mixer is generally used in the mixing station to do mixing station host, because of its relatively large power, so the production efficiency is also very high, large-scale engineering construction process must choose this type of asphalt mixer

>Asphalt mixers are used in highway construction, and if this type of equipment is differentiated according to power, there can also be differences between civil and engineering
>Apart from the difference in productivity between the two, what are the differences?
