<p>Controlling the temperature of an exothermic process carried out in a suspension of solids in a reactor system comprises adjusting the flow of solids travelling through a recycling channel (9), based on the temperature difference (T2-T1) between the upper and lower parts of a riser (5), and by adjusting the flow of solids travelling through a heat exchanger based on the temperature (T1) of the lower part (4) or the temperature (T2) of the upper part of the riser tube. Controlling the temperature of an exothermic process carried out in a suspension of solids in a reactor system comprising a wind box (2), a vertical riser (5), which is essentially not cooled, a particle separator (6), at least one set of recycling channels (9), which are not cooled, and at least one cooled set of recycling channels (12), comprises adjusting the flow of solids travelling through the recycling channel (9), based on the temperature difference (T2-T1) between the upper and lower parts of the riser, and by adjusting the flow of solids travelling through a heat exchanger based on the temperature (T1) of the lower part or the temperature (T2) of the upper part of the riser tube.</p> |
