    Preamble It is Seitron's intention, by means of this compact guide, to provide boiler installers/service technicians with a quick and easy way to understand whether a boiler conforms to the requirements of Italian Law no. 10 dated January 1991, and subsequent modifications and supplements, and Legislative Decree 192/2005.
  • Page 61 Stack loss is calculated by applying a simple formula which relates it to other easily measurable parameters: Qs = A2 + B Tf-Ta Where: A2, B = factor that depends on the fuel used Tf = flue gas temperature Ta = combustion air temperature = % carbon dioxide in the flue gas Thus in order to calculate the stack loss and hence the thermal efficiency of a plant, one must measure the two temperatures (flue gas and air) and the level of carbon dioxide contained in the flue gas (% CO...
