[0002] A boiler refers to a medium or large boiler in a power plant that provides a specified quantity and quality of steam to the steam turbine. It is one of the main thermal equipment in a thermal power plant. The boiler generally includes "water-cooled wall", "superheater tube", "reheater tube" and "economizer tube", referred to as "four tubes", collectively known as the heating surface, which can be simply understood as a device that heats water in the heating surface of the pipe to become high-temperature steam.

The boiler heating surface simulation test device described in the patent can monitor the temperature inside the furnace and the state of the heating surface in real time, which is convenient for tracking and managing the heating surface of the boiler.
