Abstract (en)
[origin: EP0651058A1] The second flow of pulverulent materials is introduced at a controlled flow rate and the control of the first flow rate is rendered insensitive to the perturbations generated by the introduction of the second flow by controlling the first flow rate directly or indirectly upstream of the point of injection of the second flow. <IMAGE>
