Ash synchrotron radiation pressurized sintering experimental device and its application method

Abstract

The invention discloses a synchronous radiation pressure sintering experiment device for ashes, and a use method thereof. An existing experiment method can not carry out nondestructive real-time observation and research on sintering. The rotary console of the device drives an ash column to rotate in a sintering furnace body; an air supply system supplies air to the furnace body; the emergent lightof a synchronous radiation light source is irradiated to the ash column and then reaches an X-ray CCD (Charge Coupled Device) camera through a transmission hole; the X-ray CCD camera transmits a shotimage of the inner change of the ash column along with time in a silicon-carbon rod heating process to a computer; an acquisition instrument collects an ash sample temperature signal measured by a K-type thermocouple and a pressure signal measured by a pressure transmitter; the computer processes the image of the inner change of the ash column along with time, the ash sample temperature signal collected by the acquisition instrument and the pressure signal measured by the pressure transmitter, and an ash column internal visual three-dimensional image corresponding to different ash column temperatures under the measurement pressure of the pressure transmitter is established. By use of the invention, the real-time detection of an ash sample internal sintering process can be realized.

Description

technical field [0001] The invention relates to a synchrotron radiation pressurized sintering experiment device and method of ash, in particular to a device and a use method for carrying out microstructure evolution behavior in the sintering process based on synchrotron radiation technology. Background technique [0002] Boiler ash accumulation and slagging are relatively easy phenomena during boiler operation. This phenomenon increases the heat transfer resistance of the heating surface of the boiler, deteriorates the heat transfer of the heating surface, increases coal consumption, reduces the thermal economy of the boiler, and may also cause The blockage of the flue gas passage affects the safe operation of the boiler, and in severe cases, equipment damage and personal injury accidents may occur. The sintering of ash is one of the main factors that cause a series of agglomeration, ash accumulation and slagging in the combustion or gasification system. Sintering is the pr...
