METHOD AND APPARATUS FOR FEEDING A PULVERIZED MATERIAL.

摘要

The present invention is referred to a method and an apparatus for feeding a pulverized material. The apparatus comprises fuel feeding means to supply pulverized fuel. Flexible means are coupled between the fuel feeding means and dosing means for the filling of the dosing means. The dosing means are closed and pressurized once that the dosing means have been filled. The pulverized material is discharged from the dosing means while controlling the pressurization during the discharge, in order to provide a continuous and constant discharge of the pulverized fuel. The apparatus includes means for detecting a minimum level or weight of pulverized fuel in the dosing means, and means for depressurizing the dosing means once that the minimum level of the pulverized fuel has been reached.
