Best Answer

They are lined with fire bricks because of the intense heat and chemical reactions that are present in the blast furnace. The temperature alone would quickly melt the outer metal shell. Different types of bricks are used in the different parts of the furnace depending on the temperature in that part of the furnace, the lowest temperatures being at the top, and the highest temperatures in the bottom in what is known as the bosh and the hearth. Abrasion and mechanical damage can also occur to the bricks, which is why blast funaces need to be shut down after a certain number of years to be relined, or shut down briefly for maintenance which would include adding more cooling in areas where the brick lining is getting too thin.

What is turndown ratio of burner in gas fired furnaces?

Turn down ratio is the maximum to minimum heat output.Turn down ratio for direct gas fired burners is 25:1, which means that the burner can modulate from 4% to 100% of full fire. Indirect gas turn down ratio is typically 2:1, which limits the heat output from 50% to 100% of full fire. Mukesh Yadav
