abstract for water tube boiler temperature

  • Boiler Research Papers - Academia.edu

    In this study, the relation between excess air ratio and boiler efficiency was investigated in a water tube boiler that has the capacity of producing 55 tons of steam per unit time at 245 degrees C and 20 bar pressure. The boiler combustion air is supplied from a fan driven by a 30 kW 1450 rpm induction motor.
