  • Measurement of Oxygen Concentration in Package Boiler Flue

    Flue Gas Oxygen Measurement - GasLab.comGet Price

  • Flue Gas - an overview | ScienceDirect Topics

    For some industrial boilers, slightly air-deficient combustion is favored at their furnaces, in order to minimize formation of gaseous nitrogen oxides. Gaseous H 2 S exists in the flue gases locally. Oxygen and sulfur partial pressures of these combustion gases are calculated as a function of air–fuel ratio at 1300 °C and presented in Table 3.Get Price

  • ABMA paper 9 00

    the boiler, the flue gases make 1, 2 or 3 passes through the water stored in the pressure vessel. For a 2-pass boiler, there is only one bank of tubes, for a 3-pass boiler there are 2 tube passes and for a 4-pass boiler there are 3 tube passes. After leaving the convective section of the boiler, the flue gases exit the pressure vessel at the stack.Get Price

  • Latent heat recovery from oxygen-combustion flue gas

    Aug 06, 2002 · The most part of energy losses in a boiler is due to the heat released by the exhaust flue gas to atmosphere. The released heat consists of sensible and latent parts. As a next generation boiler, an oxygen combustion boiler was planned and developed in Japan. The steam mass concentration of the oxygen-combustion flue gas was approximately 25% which …Get Price
