What is the typical thickness of block insulation on steam drums, mud drums, and headers?

The typical thickness of block insulation on steam drums, mud drums, and headers is generally in the range of 10-15 cm. This thickness is effective in providing adequate thermal insulation, which is essential for energy efficiency in steam systems. The insulation primarily serves to reduce heat loss from these components, thereby minimizing energy consumption and maintaining the operational efficiency of the boiler system.

Insulating these parts of the boiler not only helps in keeping the heat where it is needed but also protects personnel from potential burns caused by exposure to hot surfaces. While thicker insulation can be beneficial in some applications, the 10-15 cm range strikes a balance between effective thermal protection and practicality, as excessive thickness could lead to increased costs and space limitations.
