Coal Powder Burner for Silica Sand Dryer

For one successful silica sand dryer machine, except that it can achieve the targeted drying capacity, the related fuel consumption also is rather important which will influence the final economic benefits significantly.

In order to save the fuel cost, firstly the clients needs to find the cheapest fuel in their local market. Secondly the related fuel burning system should can burn the fuel sufficiently with less heat loss.

For example, when to use coal as fuel, in the past usually use the traditional coal fired hot air furnace, which needs the workers to feed the lump coal into the furnace manually periodically as actual need. It is old technology with high labor intensity, low efficiency, high heat loss, etc.

Sunco Machinery developed one new type coal powder burner for rotary silica sand dryer machine , and it includes coal pulverizer, coal powder feeder, coal powder burner, blower, hot air furnace.  The coal pulverizer crush the coal into coal powder, then the feeder send the coal powder into the burner for burning, blower not only supply the Oxygen, but also makes the coal powder burning in boiling type, and hot air furnace supply the burning space for the coal powder.

New type coal powder bruner for silica sand dryer machine allows pulverized coal to fully burn in a short time to produce high-temperature eddy current. It has the features of :

1. The residence time of pulverized coal in the high temperature zone of pulverized coal burner is long, so the combustion efficiency is high. The flue directly emits no black smoke, which is in the form of steam white smoke;

2. This type of pulverized coal burner is characterized by shorter temperature rise time, higher thermal efficiency, low requirements for coal quality, wide applicability of coal types and high economic benefits;

3. The pulverized coal burner has the advantages of easy ignition, fast temperature rise and greatly improved working efficiency;

4. The air supply volume and coal input of the burner can be changed as required, and the furnace temperature and flame length can be adjusted in a wide range to meet the actual needs;

5. The temperature field inside the pulverized coal burner is uniform, the heating coverage of the heated body in the furnace is large, the slag does not stick to the surface of the workpiece, and the product quality is good.

With the application of new type coal powder burner, silica sand dryer machine can have large drying capacity with high heat exchanging efficiency and less fuel consumption.
