Abstract

The invention discloses a refractory brick layer erosion rate monitoring device and method. The refractory brick layer erosion rate monitoring device comprises a data acquisition module connected with a furnace body to be monitored, and further comprises data processing modules I, II and III. The module I and the module II are both used for calculating the temperature T, the flow velocity u and the thickness delta of a liquid slag layer. The module III is an erosion rate calculation module, and the module I is used for obtaining data parameters required in the module III by establishing a multi-phase turbulent flow reaction flow database in the furnace body and adopting an interpolation algorithm. The module I is connected with the module III and is used for transmitting the calculated data parameters to the module III. The module II is used for establishing energy conservation, mass conservation and momentum equations. The monitoring device provided by the invention can realize continuous online monitoring of the erosion rate of the refractory brick layer.

Description

Technical field [0001] The present invention relates to an etching rate monitoring device and a monitoring method of a refractory brick layer. Background technique [0002] Coal gasization technology is to prepare clean synthesis gas (CO, H) by using a gasifier and coal in partial oxidation in a certain temperature and pressure conditions. 2 The process method of mixture is one of the main ways of coal cleaning conversion. Airflow bed coal gasification technology is due to the advantages of massive load, high pressure, excluding tar, representing the development trend of future coal gasification technology, and it is also the cleaner technology and mainly used technologies in coal utilization. [0003] Airflow bed gasification technology is divided into water coal pulp gasification technology and dry coal gasification technology. The gasification furnace inspector can be divided into refractory brick lining gasifier (eg, multi-blade water coal slurry) Gasification furnace (eg) ga...
