Coal Powder Spraying Machine and Pulverized Coal Injection Machine
Brief Introduction of Coal Powder Spraying Machine
Coal Powder Spraying machine is used for crushing the lump coal to some certain particle size and
further grinding,finally will get the pulverized coal after grinding, which is the important auxiliary
equipment for the furnace using the pulverized coal as fuel. Coal grinding process is the process of
coal being crushed and increased the surface area. To increase new surface area, must overcome
the binding force among the solid molecules,thus need to consume energy.
Coal injectionmachine researched and developed by our company can save 30%-40% of the amount of coal than the
traditional stoves.
Widely Application of Pulverized Coal Injection Machine
Coal injection machine is widely used for rotary kiln , dryer, rotary dryer, Stationary furnaces of heat equipment drying
dehydration, calcination and tempering in building materials, metallurgy, chemical, can be instead of the fuel oil,coal
gas and heat source equipment that using the electric heating.
Structure of Lump Coal Grinding and Injection Machine
Coal injection machine is composed of feeding part, crushing chamber, high pressure fan and powertrain, total
four parts; Coal injection machine is used with powdered coal burner as well.
Working Principle of Coal Briquette Crushing and Grinding Machine
Coal feeding, crushing,spewing, separation procedure were done on the host. The flame temperature
adjustment can be achieved by controlling the valve groups and coal quantity.After the separation of
crushing chamber, the particles with less than 0.1mm will be spewed and burned, at the same time,
avoid the large particles were spewed directly.
Coal injection machine has extremely high burning out rate, mainly because our company adopts the
pulverized coal injection technology, namely, expanding the contact area between coal and oxygen in
the air to intense and rapid oxidation process; then, the rapid operation and rotation of pulverized coal
air flow makes the volatile gas film quickly out from the fixed carbon to speed up the carbon combustion.
The rapid combustion of coal, flame fast run, semi-closed combustion chamber and reasonably air supply, which can not
only led to the burning, but also greatly reduce the heat loss of coal burning. Coal injection machine can make full use of
the raw coal and opened up a new road. The pulverized coal injected into the combustion chamber is almost instantly fire
to produce the heat and supply the heat for rotary dryer,except little heat be absorbed by the refractory brick, the rest
most heat are fully entered into rotary dryer. The coal injection machine has several advantages as follows: full burning,
heat supply stability, avoid the instability due to caused by the lower coal.
