Patent ID: 8307692

Claim:
A method for testing and calibrating a dust load flow measuring system, comprising: using an input sluice as a receiving container; providing a dust delivery line leading from a metering vessel to a gasification reactor; during the testing and calibrating: disconnecting the dust delivery line from the gasification reactor in a delivery direction downstream of an installed dust load flow measuring technology; connecting the dust delivery line to a calibration line connected to the input sluice in a delivery direction downstream of the installed dust load flow measuring technology; providing the input sluice with a weighing facility, such that a load of a content of the input sluice containing pressurized fuel dust is determined; controlling a first differential pressure between the metering vessel and the input sluice to a predetermined value using a pressure control valve; and determining a dust load flow in a time interval using the first differential pressure and a change in the load in the input sluice, wherein when the calibration line is connected, the pressurized fuel dust flows from the metering vessel through the delivery line into the calibration line and into the input sluice.
