FIELD: oil and gas production. ^ SUBSTANCE: invention can be used in chemical-recovery industry. Coke is loaded into coke-cooler plenum 8. Circulating gases are removed from coke-cooler plenum 8 with the help of draft system 7 and supplied into waste heat boiler 2. Produced superheated steam is removed from waste heat boiler 2 along steam line 9. Downstream waste heat boiler 2 circulating gases again arrive into coke-cooler plenum 8. In order to control actual flow rate of circulating gases and maintenance of superheated steam temperature at specified level, data obtained from superheated steam temperature sensor 1, sensor 3 of circulating gases temperature at the inlet to waste heat boiler 2, sensor 4 of circulating gases temperature at the outlet from waste heat boiler 2 and sensor 5 of circulating gases flow rate is sent to control unit 6. After processing of obtained data, control unit 6 generates signal of draft system 7 control. ^ EFFECT: invention makes it possible to increase accuracy of superheated steam control and to reduce power inputs. ^ 3 cl, 1 dwg |
