  • Water Circulation Modeling Of a Recovery Boiler Undergoing

    When feed water flow to the boiler stops, the water level inside the boiler starts to sink. This exposes the tubing to hot steam, causing dryout [2]. Dryout occurs, because there is no way for the steam to absorb heat in such a way as water does by evaporation. Poor heat absorption of steam causes immediate rising of the tube wall temperature.Get Price
