Texaco slag contains a large number of white particles enclosed within it
Thread Content
The slag is gray-brown in color, glassy in texture, about the size of a thumb, and contains numerous white particles within it. What are these white particles, and are they related to the temperature of the vaporization furnace?
Did the original poster just discover this phenomenon? It is quite dangerous when this phenomenon occurs. Because these are likely to be particles formed by the erosion and abration of the alumina refractory bricks in the insulation layer of the gasification furnace. Alumina refractory bricks are white bricks that serve primarily as insulation, and they are placed on the outer layer of the three layers of refractory bricks in the gasification furnace. Generally, such refractory bricks do not come into direct contact with the process gas flow, so they are less likely to get damaged. If such a situation occurs, it indicates that the refractory bricks in the gasification furnace have been severely damaged, and it is necessary to stop the operation immediately for maintenance! It is also possible that the refractory pouring material on the arch of the gasification furnace was washed away by intense vortexes of process gases. However, both of these possibilities are accompanied by overheating of the furnace walls or vault, I wonder if the original poster has noticed that?
