Introduction of Coal Burner

RM series pulverized coal burner is a new type coal combustion burner supported by FMJ series coal pulverizer. Coal Burner mainly consists of coal burner, coal pulverizer and igniter. Pulverized Coal Burner has many outstanding characteristics such as smoke abatement, energy conservation, environment protection, working conditions improvement, reduced labor intensity, etc. Pulverized Coal Burner is an ideal heating equipment.
Environment friendly: combustion completeness ≥95%, air black: Ringelmann 0-I grade, no harm to environment.

Main Structure of Coal Burner

Main Features of Coal Burner

1. Coal powder stays in the hot zone of pulverized coal burner for long time, it kinds increases the combustion efficiency. Vaporous white smoke directly gets out of the chimney instead of black smoke.
2. The heating process is shortened, rising the thermal efficiency, and low requirements on coal quality, brings high economic efficiency.
3. Easy ignition greatly increases the working efficiency.
4. The air and coal volume can be changed on demand, besides, the burner temperature and flame shape can be adjusted in a wide range to meet the actual need.
5. The temperature field is even and large, the slag won’t stick on the surface, and the heating effect is powerful.
6. Application of exclusive high-performance heat resistance bricks to extend the serivce life.
7. Newest coal pulverizer with special made coal hammer that can produce coal particle ≥200 mesh.
8. Automatic pulverized coal adding devices, frequency control system, remote control.
9. Reasonable structure, excellent overall performance: good looking appearance, complete supporting facilities, tiny resistance and easy maintenance.

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.
(9) Environment friendly: combustion completeness ≥95%, air black: Ringelmann 0-I grade, no harm to environment.
Note: These indexes are the lowest requirements for the coal, the better coal will be better at practice.
