Well proven air motors are astoundingly innovative
A powerhouse in the drainpipe - and supplier of green electricity
Four applications demonstrate powerful versatility of air motors.
Dagmar Dübbelde, from drive specialists DEPRAG SCHULZ GMBH u. CO., described the air motor as a “universal genius”, and gave four impromptu and exciting examples of how such motors are deployed. As a compact power pack, it helps a cutting robot to battle its way through the muck inside the drainpipe. The air motor adds enormous power to a truly amazing transporter device. As an ATEX-compliant brake motor for potentially explosive areas its job here is to optimise a barrel emptying system. As an innovative GET turbine generator its energy recovery credentials are extremely “green”; it even generates power from small amounts of process gas.
Temperatures globally have been rising inexorably for 30 years now. Researchers and industrialists have struggled to counter the effects of climate change with innovative products and processes. At its test laboratory DEPRAG is producing the prototype of Furore, its Green Energy Turbine generator (GET), which is able to convert even small quantities of unused process gas into usable energy. The ambitious project is now sufficiently far advanced that it can be tested in conjunction with appropriate partners. DEPRAG Managing Director Dr. Ing. Rolf Pfeiffer said: “In a small, local energy recovery plant our progressive new turbine generator can convert even tiny amounts of residual energy, of between 5 and 20 kilowatts, into electric power.”
The innovative DEPRAG turbine generator is based on the expansion turbine principle. The GET represents a compact unit consisting of a turbine and a generator that has been developed especially for this application. Excluding its control cabinet, it is not much bigger than a shoe box, and can be used locally on the “plug and earn” principle wherever unused gas either exits from the industrial process or where the pressure level is decreased from high to low.
The gas flows into the turbine, where it is pushed through nozzles and accelerated. As it meets the blades on the turbine and is diverted, it releases its energy. The kinetic energy is converted into electrical energy inside the generator. The turbine and generator represent a compact unit, and share a common shaft. The result is that the turbine rotates, the generator rotor rotates at the same speed - and electricity is produced!
