Fertilizer indirect heat transfer dryer view heat transfer

Jan 01, 2013 Heat transfer characteristics of three typical heat carriers, i.e. saturated steam, thermal oil and flue gas, for indirect paddle dryer were studied. The convective heat transfer coefficient (HTC) of the three heat carriers were theoretically calculated. The contact resistance and penetration resistance were also determined by the penetration

    Indirect heat transfer uses conduction, radiation or convection to achieve temperature change. There are ... As the product (ex. powder, fertilizer, sugar) enters the drum dryer, the rotating mechanism lifts the material up onto a series of internal fins lining the outer walls of the dryer. As the material flows toward the discharge end, it

    Types of Dryers The most important feature of a heat-drying sys- tem is the dryer. Typically, the rest of the facility is designed around this integral piece of equip- ment. Dryers can be classified as direct, indirect, or other. Direct and indirect dryers typically have been most successful for

    Mar 01, 1999 Most applications employ steam as an indirect source, using either a heat exchanger to transfer heat to a gas carrier or a jacketed vessel or drum to heat a surface. It also is used as a direct heat source to achieve effective drying. The amount of energy that can be carried by steam is related to the pressure at which the steam is delivered

    A dryer is used for the evaporation of liquids from solids. Most types of dryers are indirectly heated with either an internal exchanger coil or an external heat transfer jacket. This allows the use of remote heating and cooling utilities such as water or oil to precisely control temperatures inside the dryer
