EBICO EC-C electrical ratio adjusting pulvarized coal burner is an intelligent one with high-precision developed by Ebico for asphalt mixing plant, which can be adapted to 1000-5000 type asphalt mixing plant with Integrated body design, modularized skid-mounted and efficient and convenient maintenance.

Main Features:
1 The primary air is direct-flow, which enhances the penetration of pulverized coal.

2 Enriched pulverized-coal ring that is equipped within the primary air duct can separate the primary air and powder mixture, improve the low-load stable combustion capacity and reduce Nox emissions.

3 Setted with a transitional direct-flow air outside the primary air, the burner can enhance the air classification and properly prevent the coal powder from fastly outward diffusion.

4 Adjustable swirler in secondary air duct can flexibly adjust the flame size to better match with the boiler.

5 Equipped with internal combustion chamber space to accelerate precipitating volatile components, improving low-load combustion stability, and reducing ignition fuel consumption.

6 Tertiary air is also a direct-flow which can effectively avoid coking phenomenon.

7 Using flue gas circulation technology (FGR) to further reduce Nox emissions.

8 The burner operates normally by first igniting with natural gas/LPG. Once the combustion chamber temperature reaches the set point, pulverized coal begins to be injected and co-fired for a period of time. The gas supply is then cut off, and the feed of pulverized coal is reasonably regulated according to boiler load requirements.
