Test Kiln „Rotary Drum Furnace“

Our gas-tight test rotary drum furnace, with a heated length of 3,000 mm, a diameter of 300 mm and a maximum furnace temperature of 1,100 °C, offers a wide range of test possibilities for short and long-term tests under production-like conditions. Upscaling from laboratory scale to production scale is therefore also possible.

In addition to tests under oxygen atmosphere, it is also possible to carry out tests under protective gas atmospheres such as nitrogen or hydrogen. The rotating tube is made of high-quality Inconell and can be replaced at the customer's request.

An automatic filling device allows a continuous operation of the system. Dwell times and throughputs can be additionally controlled by a pneumatically operated height adjustment.

In addition, ONEJOON has various test benches to continuously develop essential components of the furnace technology.

For example, new insights into the flow behavior and exhaust gas composition of different burner systems in the boiler room can be gained at our burner test stand. Furthermore, it is possible to examine the resistance of our sealing system under different operating conditions in long-term tests and also to check the effects of pressure changes.
