  • Yarrow boiler - Wikipedia

    Natural circulation within the boiler causes the feed water to flow from the steam drum through the down-comers to the boiler furnace. When the water reaches saturation temperature it flows back to the steam drum due to a change in density, steam and water are again separated in the steam drum and the cycle continues. Figure 1 indicates a basic representation of natural circulation within a boiler circuit.Learn More
