The apparatus consists of a small test cylinder. The cylinder is heated by a constant temperature water bath, till steady state is reached. During heating, temperature of the cylinder is function of time and hence, heating of cylinder is unsteady state heat transfer. The temperature of cylinder is measured with the help of temperature sensor inserted in the center. The hot water bath is provided with a heater and is controlled by digital temperature controller. An agitator is also provided to maintain the constant temperature. Electricity Supply: 1 Phase, 220 V AC, I kw Bench area of 1.5m x 1.5m
Fluidisation And Fluid Bed Heat Transfer Unit

ALPHA CHEM-1312 Fluidisation And Fluid Bed Heat Transfer Unit Application of fluidised beds is more widespread in industry than is usually appreciated, covering such diverse fields as power generation to food processing. The objective of the unit is to investigate the gas flow through a fixed and fluidised bed and to measure the heat transfer rate and coefficients for comparison with convective heat transfer rates in air. Fluidisation takes place within a transparent chamber and the range of bed material supplied can be rapidly changed. Alternative locally sourced bed materials and air distributors can be easily utilised for student project work. Fluidised Bed designed for educational studies and using air as the fluidising medium. The unit incorporates a glass chamber containing the bed material and an electric heater for heat transfer studies. High quality glass reinforced plastic on which the following components are mounted: Variable Transformer to vary the heater power input. Volt and Ammeter to indicate the heater power input. Ranges 0 to 250 V amd 0 to 3 A. Flow Meters to measure air flow through bed. Range 0.15 to 3.5 litres/sec. Digital Thermometer to indicate the temperatures of heater surface, air inlet and probe. Resloution 1ºC. Manometer to measure pressure drop through bed. Safety Features include fusing and earthing of all components and heater temperature controller. Experiments : Observation of the behavior in a fluidised bed of a wide range of granular maerials, from onset of fluidisation to entrainment. Measurement of air flow and pressure drop through a variety of granular materials, as packed and as fluidised beds. Investigation of the effect of distributor design on bed behaviour. Investigation of the effect of: Superficial velocity Depth of immersion particle size on surface heat transfer coefficient for a hot surface in a fluidised bed Demonstration of separation by article size and density. Specifications : Column : Material Borosilicate Glass Dia. 80 mm. Total Length 500mm. Cyclone Separator : Material Stainless Steel, Compatible Capacity with collector. Air Circulation : By forced draft fan, Arrangement is done vary the air flow rate. Heating Chamber : Compatible capacity Heater : Nichrome wire heater Temperature Sensors : RTD PT-100 type. Control panel comprises of : Digital Temp. Controller : 0 199.9°C (For Hot Air) Standard make on/off switch, Mains Indicator etc. Instruction Manual : An ENGLISH instruction manual will be provided along with the Apparatus
