What impact will stack temperature have on boiler performance?
Stack temperature is the temperature of the combustion gases (dry and water vapor) leaving the boiler. A well-designed boiler removes as much heat as possible from the combustion gases. Thus, lower stack temperature represents more effective heat transfer and lower heat loss up the stack. The stack temperature reflects the energy that did not transfer from the fuel to steam or hot water. Stack temperature is a visible indicator of boiler efficiency. Any time efficiency is guaranteed, predicted stack temperatures should be verified.
Stack loss is a measure of the amount of heat carried away by dry flue gases (unused heat) and the moisture loss (product of combustion), based on the fuel analysis of the specific fuel being used, moisture in the combustion air, etc.

On March 20, 2025, the Guizhou Jinyuan Zhijin “Replacing Small Units with Large Ones” Relocation Project (2×660 MW), under State Power Investment Corporation, successfully achieved the first ignition of its boiler. This project replaced traditional oil-fired ignition fuel with liquefied natural gas (LNG), setting a new precedent for employing clean energy in 660 MW ultra-supercritical “W” flame boilers. As a key equipment supplier for this project, ZOZEN Boiler prov...15 Jul 2025
