Used for 25-320 t/h asphalt mixing plant.
RM series rotation type coal burner features:
1. Adopt new design structure, which changed the principle of traditional burner, adopt rotation type combustor to solve the imperfections of traditional burner(easy slagging, incomplete combustion).
2. High flame temperature, energy saving, burning sufficient.
3. Adopt high performance refractory brick, prolong service life.
4. 24 hours continuous production, no need do slag removal work everyday.
5. Production cost is low, the cost is only about 1/3 of the oil burner.
Requirements of fuel:
1. Use 0 # diesel for oil burning igniter;
2. Requirements for coal used for burning:
(1) Mark of coal: bituminous coal;
(2) Gross calorific value:≥5000kcal/kg (≥ 20000kJ/kg); Net calorific value:≥4200kcal/kg;
(3) Volatile matter:≥25%;
(4) Ash Content: ≤10%;
(5) Total moisture: ≤35%;
(6) Inherent moisture:≤14%;
(7) Total sulphur:≤1%;
(8) Particle size:≤20mm.
Note: These indexes are the lowest requirements for the coal, the better coal will be better at practice.
3. Environment friendly: combustion completeness ≥95%, air black: Ringelmann 0-I grade, no harm to environment.
