Rotating tube furnace range TSR

LEADING HEAT TECHNOLOGY

• Excellent temperature uniformity
• Fast heat-up and cool-down rates
• Unsurpassed temperature uniformity along the entire heated length

• Low energy consumption
• Low external case temperature
• Designed for longevity

TEMPERATURE CONTROL & COMMUNICATIONS

TSR rotating tube furnaces are equipped with ethernet communications and a programmable controller with 24 segments as standard:

• Single zone furnaces fitted with Carbolite Gero EPC3016P1 controller
• Three zone furnaces fitted with Carbolite Gero CC-T1 touch-screen controller

OPTIONS

• Over-temperature protection (recommended to protect valuable contents and for unattended operation)
• A range of sophisticated digital controllers, multi-segment programmers and data loggers is available. These can be fitted with RS232, RS485 or Ethernet communications. 

MODIFIED ATMOSPHERE AND MATERIAL MOVEMENT

The Carbolite Gero TSR rotating tube furnace may be equipped with gas connections to accommodate modified atmosphere applications.

The gas system is built into the frame of the furnace and required gases and control method must be specified at time of order. Options include manual flowmeters or digital mass flow controllers.

The TSR is available with a choice of different work tubes. Please note that the maximum operating temperature is dependent on the properties of the work tube material selected.

To accurately control the flow of sample material into the furnace, the TSR is fitted with both a 5 litre hopper and vibratory feeder, as standard. A 5 litre collection hopper with manual discharge valve is also included to safely gather processed material. 

OPTIONS

• Gas connection kit to enable operation under modified atmospheres
• Inert gas package modules allow for the use of up to 3 non-reactive gases (available with either manual or automatic control)
• Input hopper with screw feeder

Standard quartz work tube and optional metallic work tube

Gas flow control by a digital flow meter

CUSTOM DESIGN OPTIONS

We have a wealth of knowledge built up over years of assisting customers with their rotating tube furnace applications. Certain applications will benefit from a selection of custom options including:

Material movement options to aid movement of the material including:

• Metallic helical work tube inserts. These are used to control the movement of material through the work tube
• Feed knockers and agitators
• Scraper bars or wires within the work tube
• Water cooled collection hopper
• Automated discharge valve
• Steam injection - digitally controlled evaporator/mixer unit with mass flow controllers for the delivery of a carrier gas (N2) and water

ANGLE OF INCLINATION

To assist in the flow of material through the work tube, the TSR can be tilted to a maximum of 6° using the manual winding wheel. By adjusting the angle of inclination, the operator can control the residence time of the material within the heated zone of the rotating tube furnace; the ability to change the angle ensures that the TSR has the flexibility to process many different materials with various grain sizes, from granules to powder.

TORREFACTION & BIO-COAL

Torrefaction is a thermochemical process carried out in the absence of oxygen to cause the partial decomposition of biomass. Water and volatiles are released from the biomass to leave a solid, dry material known as bio-coal. For some applications, bio coal can be used to replace traditional fossil fuels, thus helping to reduce CO2 emissions.

In this video, both RETSCH cutting mill SM 300 and the CARBOLITE GERO rotating tube furnace TSR have been used as a part of a torrefaction process to create bio-coal fuel. 
The Verder Scientific companies provide solutions to support your process every step of the way, from sample preparation and analysis, to heat treatment, and more.
