    Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressureLearn More

  • Corrosion and fatigue failure analysis of a forced draft

    Jun 01, 2011 · 1. Introduction and background. The failure analysis of a forced draft fan (FDF) blade of a boiler unit in a fossil power plant is presented. The investigated axial fan consists of two stages of blades which have been in service condition for about 200,000 h (according to the specifications given by the manufacturer, the expected life of these blades is 280,000 h).Learn More
