  • Flue Gas - an overview | ScienceDirect Topics

    Marek Pronobis, in Environmentally Oriented Modernization of Power Boilers, 2020. Stack. Flue gas temperature at the inlet to the stack (chimney) t stack 1 and at the outflow of it t stack 2 are important preconditions for the design of the flue gas system of the boiler. These temperatures are strongly dependent on the stack design and generally are specified by the manufacturer.Learn More

  • Flue gas heat exchanger for steam boilers - Bosch

    The flue gas flows at the boiler outlet inherently have heat potential at a high temperature level. A flue gas heat exchanger is great to use in order to prevent unnecessary flue gas losses. This efficiency component extracts heat from the hot flue gas and, in return, preheats feed water – this, in turn, reduces the fuel expenses for steam Learn More

  • Forbes Marshall | SteamPedia | Understanding Stack Losses

    A common trend observed is, as boiler is operated continuously, the measured outlet temperature of flue gases increases. After operation for a few months, significant rise in flue gas temperature and hence stack losses is observed. The reason behind this is, as a boiler is operated, scales are formed on the boiler …Learn More


    The flue gas exit tempera ture from a boiler is usually maintained at a minimum of 200 o C, so that the sulphur oxides in the flue gas do not condense and cause corrosion in heat transfer surfaces. When a clean fuel such as natural gas, LPG or gas oil is used, the economy of heat recovery must be worked out, as the flue gas temperature may be Learn More
