Five main salient feature compared with other common coal burning system:
1. Mechanized coaling:Loader coaling, lower labour intensity.
2. Automatic rotation : enhance the fireproof material service life.
3. Automatic walking: the burner can be moving by the motor drive at the stand.
4. Automatic ignition: There is a electron ignition device which can ignite automatic safely.
5. Automatic temperature self-control: It adopts temperature regulation meter trailing the medium temperature and adjusting coal supply capacity in order to guarantee the medium temperature requirement.
Pulverized coal burning device Main function and characteristic
Good adjustability for the blaze shape.
The different proportion of the burner wind inside and outside and the export jet stream type can adjust the air volume stepless, so that it could get the suitable flame shape in any working condition.
Combustion fully,energy saving
The coal burning system can effectively reduce coal consumption because
Bating harmful gas emission actively
There is a high temperature flue gas back-flow forming negative pressure district in the head of the coal burning system when it working, which can ignite powder coal quickly and make the temperature curve which follow the cylinder changes smoothly. Bating harmful gas emission actively.
Reasonable structure and good performance and characteristic overall
Good appearance, complete mating facilities, small resistance, frame adjustment flexibly and quickly.
New technology and material make it long working life.
We use the special wear resistant material or heat treatment technology for the common abrading section of the coal burning system, which make the wearing life of the burner's key position improve 5-10 times. The head and sprayer of the burner adopt wear resistant steel material,so that it has a long service life even under the condition of 1100ºC.
Equipped with fuel supply device
The oil supply adjust easily,and there is a special nozzle structure on the burning torch which has good atomization and ignition easily.High voltage spark ignition device,provide a key ignition, high ignition success rate.
Control pollution
Because the pulverized coal is fully burned and the harmful gas emission is small, the combustion tail gas passes through the dust collector, effectively controlling environmental pollution.
Cost savings
Due to high fuel price, it is significantly lower the price of the coal. This can save a larger cost for users and make the users earn cost in a large project in the same year.

Economic analysis (according to material price in China)
At present, for asphalt mixing plant, to heat aggregate, most of fuel is diesel oil or heavy oil. But, with the increasing of energy source, fuel cost is becoming big expends of asphalt batch mixing plant. Therefore, most of contractor use coal as fuel instead of oil to reduce the cost. Now, we're comparing the difference between coal burner and oil burner(take RD175 as a sample)
Under standard condition, RD175 works one hour normally, capacity of 160t, heavy oil consumption is 6.5kg/ton, coal consumption is 10kgs/ton, the price of heavy oil is RMB3,300/ton, for coal is RMB950/ton, power price is RMB1.15/degree.
Oil burner adopts Italy : drawing fan power: 37kw; oil pump: 2.2kw; oil heater: 30kw. Air compressor: 15kw.
Coal burner adopts Roady RMII2000-00, coal crusher: 2x45kw;coal screw: 2x1.5kw(frequency timing); burning power: 19.4kw; oil supply: 1.5kw; vibrator power: 0.25kw;
When using oil burner: power consumption: 84.2kw/h
Cost on power: 84.2x1.15=96.83
Oil consumption: 160x6.5=1040kgs
Cost of oil: 3300x1.04=3432
At this condition, burning system cost is:
96.83+3432=3529/h
When using coal burner, power consumption: 113kw/h
Cost of power: 113x1.15=130
Coal consumption: 160x10=1600kgs
Cost of coal: 950x1.6=1520
At this condition, burning system cost:
130+1520=1650/h
By comparison, we are easily find that the cost of RD175 working one hour, cost of using coal is 1779(3529-1650=1779) less than using oil, then will save around 20,000 per day. Therefore, by adopting coal burner can reduce the cost greatly and bring more benefit to customers. In summary, Roady RM series coal burner is wisdom choose for customer to reduce cost.
