Abstract (en)
[origin: WO2018234481A1] Injection of a process fluid into a shaft furnace by means of n injectors, whereby the status of said n injectors is tested by supplying a test fluid to each injector at a predetermined pressure, measuring a corresponding test fluid flow rate through the injector and comparing the measured test fluid flow rate with a predetermined safe flow-rate range or supplying the test fluid to each injector at a predetermined flow rate, measuring the pressure drop over the injector or a nozzle part thereof and comparing the measured pressure drop with a predetermined safe pressure-drop range.
