Experimental method and device for simulating erosion of furnace wall of high-temperature reaction furnace

Abstract

The invention discloses an experimental method and device for simulating erosion of a furnace wall of a high-temperature reaction furnace. The device comprises an outer barrel for preparing a simulated furnace wall, an inner barrel, an upper flange cover plate, a lower flange cover plate, temperature observation points laid in the same horizontal section between the inner surface and the outer surface of the simulated furnace wall, temperature sensors arranged at the center of the bottom of a furnace cylinder and used for representing the temperature of a high-temperature medium in the furnace, a heating device I used for preparing the wall surface of a simulated furnace cylinder, a position-adjustable heating device II used for locally heating internal fluid, a temperature controller connected to the heating device I and the heating device II and arranged in a data acquisition box, a temperature signal converter, a bus signal converter and a data acquisition processor with a serial communication interface and a man-machine interaction function. According to the method and the device, the phenomenon that the furnace wall is eroded by the internal high-temperature medium in an operation process of the high-temperature reaction furnace can be simulated, and the reliable accuracy of various algorithms used for solving the furnace wall erosion problem is verified through the data of the temperature observation points and the result of the actual experiment.

Description

technical field [0001] The invention relates to the field of safety diagnosis of chemical and metallurgical equipment, in particular to an experimental method and device for simulating wall erosion of a high-temperature reaction furnace for a reaction furnace with high-temperature fluid inside. Background technique [0002] In the field of chemical industry and metallurgy, some process equipments have long-term flow of high-temperature fluids. The walls of such devices usually bear high temperature or pressure. When the critical value is reached, the furnace wall will be gradually corroded and thinned or even cracked, seriously affecting production safety. The ironmaking blast furnace is a typical representative device of this type of high temperature reaction furnace. The blast furnace generally uses steel plates as the furnace shell, and the shell is lined with refractory bricks. The lining of the hearth near the taphole will be subjected to high temperature for a long tim...
