Hi all,
I am going to install a tar measurement system for tar collection and measurement of the syngas that exits my pilot scale gasifier, which is by the way a rotary kiln, and I am following a European standard procedure for tar and particle measurement for biomass gasification available on www.tarweb.net. My feed stock is mainly plastic mixtures, rubber. In the procedure it is suggested that the first module, which includes tubes, valves, fittings, and filters, etc. must be kept at high temperature (about 300-350 C), however, I could not find any trace heating that can heat the module up to that high temperature. Could you please share any experience or thought that can make that trace heating possible.
Dear Mohammadi,
You can try for heating tape with insulation Also induction coil heater can definitely go up to the temperature mentioned.
Use the Omega high temperature trace heating tapes:

Use a suitable type K thermocouple under the heating tape and controller so you don't fry it and insulate it well.
Dear Mohammadali Mozafarian ,
As Mr. Cordner Peacocke wrote, omega trace heating tapes are one of the best options you have, especially if you are in the US. In Europe, you can also find very good heating tapes from SAF Wärmtetechnik GmbH ( https://saf-gmbh.de/en/products/laboratory-technology/heating-tapes.html) which is a German manufacturer. Both have heating tapes that can reach up to 900C.
However , I strongly recommend you insulation plus a PID loop in order to keep good control of the trace heating, as Mr Peacocke said. Therefore you should invest also in a glass fiber insulation, a good K type thermocouple and in a decent PID controller.
