The invention discloses a device and a method for monitoring the thickness and temperature of a refractory brick layer. The monitoring device for the thickness of the refractory brick layer comprises a measuring part connected with a furnace body to be monitored, a calculating module I, a calculating module II and a calculating module III; the furnace body to be monitored is a gasification furnace and sequentially comprises a liquid slag layer, a refractory brick layer and a metal wall from inside to outside, and the refractory brick layer sequentially comprises a fire facing brick layer, a back lining brick layer and a heat insulation brick layer from inside to outside; the calculation module I is used for calculating the thickness of the liquid slag layer through a mass conservation equation in the flowing heat transfer process of the liquid slag layer; the calculation module II is used for calculating the heat flow density passing through the metal wall; and the calculation module III is used for obtaining the thicknesses of the fire facing brick layer, the back lining brick layer and the heat insulation brick layer. The monitoring device and the method provided by the invention can accurately monitor the thickness of the refractory brick layer by analyzing the flowing and heat transfer processes of the molten slag. |
