How Coal Feeder Work In Volumatric Mode

The harman magnum Stoker

coal We do not recommend burning wet coal however we realize if it s the only coal you have it is better to burn it than freeze If you must burn wet coal the feed rate must be increased in order to get the same size fire As the wet coal in the hopper dries out the feed rate must be decreased If you don t the feeder will over fire

Difference Between Volumetric And Gravimetric Coal Feeder
