    Thus, this study used a co-current rotary dryer. The drying gas temperature was set as 400 C, which is the optimum drying temperature for typical rotary dryers (Li et al., 2012). The residence time of the EFB was set so as not to exceed the average residence time of a typical rotary dryer of 17.5 min (Girovich, 1996)

    Jun 01, 2020 Plate heat exchangers are suited for low or medium pressure applications — from 176 to 392 F (80 to 200 C), with pressures up to 25 bar. Common industrial applications for plate heat exchangers include closed-loop secondary circuit, pasteurization and waste heat recovery. Shell-and-tube exchangers, by contrast, excel in high temperature

    In principle, a flue gas heat exchanger can be used for virtually any solid fuel. For the use of a heat exchanger, only the medium between which the heat exchange takes place is of interest. A distinction is made here between air-air, air-water, water-water or water-oil. Only the heat energy is exchanged or transferred, the actual substances

    Co-Current Vs. Counter Current Drying

    Many factors are taken into consideration when designing a rotary drum dryer that can both efficiently and effectively dry a material. Factors such as the material’s bulk density, heat sensitivity, particle size, and flowability, among others, all interact to influence how the material will behave in the dryer, and subsequently, how the dryer should be designed to optimally

    How a rotary regenerative heat exchanger works?

    Rotary regenerative heat exchangers are used for heat recovery, and are designed to transfer heat (non-hygroscopic version), or to transfer humidity (hygroscopic version) while simultaneously maintaining the ability to transfer heat from the outlet air to the inlet air. The heat or humidity transfer takes place in the rotor, one half of which reaches into the hot outlet air
