Description

SPIRAJOULE: ELECTRICALLY HEATED SCREW CONVEYOR Spirajoule is eletrically heated screw conveyor proven for 20 years in industrial operation. Technology allows perfectly controllable, thermal processing of organics and minerals. Continuous heating of organics and minerals Spirajoule® is a dedicated equipment for a continuous thermal treatment in temperatures up to 850 degree C, basing on a hollow shaft screw conveyor heated by a low voltage current. The screw is made from electrically conductive material and is connected to an electricity power supply. Electricity is conveyed from the power supply by the specially design components located at both sides of the screw. The passage of electronic current through the conductor (screw) generates heat, which is as a result of Joule heating (also known as Ohmic heating or resistive heating). HEAT TREATMENT IN CONTROLLED ATMOSPHERES The temperature of the screw is maintained due to the joule effect and precisely controlled. The product that enters the reactor conveyed and remains in the continuous contact with the heater while it is being transferred. The particles of feedstock are heated in an uniform manner while passing through the reactor. Processing is possible in adapted, oxidizing, reactive or inert atmosphere achieved by coating with selected gases. Fossil fuels free. Free of fossil fuels – no off-gases. Spirajoule allows heating materials exclusively by electricity, allowing to carry the process without difficulties related to burning conventional, fossil fuels and off-gases generation. Equipment can be powered exclusively from clean, carbon-free sources if needed.
