Explosion proof design coal grinding powder machine in order to reach the international standard production of coal mill, coal system component design must bear the pressure of 344kPa
In order to resist, possible explosion pressure. According to the requirements of anti explosion capacity of coal pulverizer should be higher. In order to improve the coal saving machine in China
The backward situation of our country from 20 at the end of the world has from developed countries the introduction of various series of medium speed coal mill, and actively study abroad first
In the machine, based on the introduction of digestion and absorption, after decades of efforts, China's production of domestic coal pulverizer, and the finger
Standard has been in line with international requirements, the production level has been greatly improved.
The introduction of domestic coal powder spraying machine has an external spring loading system, the loading system has the advantages of simple structure, low load, flat
Steady operation, low maintenance rate, high reliability and less additional power, etc.. Because of the large change range of coal in China, strong wear resistance,
And the ash is high, so the performance design method of the coal mill is still in our country when introducing the foreign coal saving machine.
To solve these problems, China in the introduction of foreign advanced technology at the same time, also introduced the coal grinding machine grinding output correction coefficient calculation formula, Qu
Thermal calculation software for line and coal mill. Milling output calculation correction factors is based on the output. Correction factor
Grinding degree, pulverized coal fineness, moisture, but does not include the impact of ash. The type curve and calculating formula of coal mill in China are based on a large amount of coal and
Summary of the combustion experiments, it is more suitable for China's coal species.
Coal grinding powder spraying machine has high burning rate, because effectively the pulverized coal injection technology specialty, namely the maximum
Expanded coal combustion and oxygen in the air contact area to contribute to the intense and rapid oxidation process. Because of the rapid movement and rotation of the pulverized coal flow.
, so that the volatile gas film can quickly break away from the fixed carbon, thus speeding up the carbon burning rate.
