What temperature is required for pyrolysis with different feedstocks?

The pyrolysis temperature required for waste to fuel pyrolysis machine to recycle different feedstocks depends on the types and states of the processed feedstocks. For different types of raw materials, the pyrolysis temperature will be different. Also, the pyrolysis temperature will vary from the other characteristic of feedstocks, such as water content. The common pyrolysis feedstocks are tires, plastics, rubber, sludge, coal and so on.

Pyrolysis machine for processing different materials

The following is a brief introduction about the different pyrolysis temperature for waste to fuel pyrolysis machine of different feedstocks:

1. Tire pyrolysis temperature

Tire is the most commonly used raw material for waste to fuel pyrolysis machine on the market, and it can begin cracking at a temperature of about 260 degrees during the pyrolysis process, and the temperature is basically maintained at 320 to 350 degrees in the later stage.

2. Plastics pyrolysis temperature

The types of plastics are more complex than tires. Common types of plastics are PP, PE, PS, ABS, aluminum plastic, paper mill waste and so on. Due to the wide variety and complex composition of waste plastics, the pyrolysis temperature range are not very fixed. In most cases, the pyrolysis temperature of waste plastics is better in the range of 260~320°C.

However, it should be noted that PE plastic will produce a special product during the cracking process, that is, paraffin wax. The supplier of the waste to fuel pyrolysis machine must have a plan to deal with the paraffin in order to avoid the risk of frequent plugging of the plastic during the pyrolysis process.

3. Sludge pyrolysis temperature

Sludge and tar are a special kind of raw materials, most of which are semi-solid or flow viscous. However, there are many types of this feedstock, including tank bottom sludge, ship cabin sludge, oil field sludge, sludge in steel industry, etc. Due to the different water content and oil content, the pyrolysis temperature range is also very different. Generally speaking, this type of raw material has high requirements for the control of pyrolysis temperature and process, and the common pyrolysis temperature for this feedstock is between 300 and 400 degrees.

It can be seen that the temperature required for pyrolysis process is different for different raw materials. If you want to know what the temperature of your raw materials is, you are welcome to send the photos of your raw materials to the DOING professional business manager for review, in order to make a detailed answer.

As a professional manufacturer and supplier for waste to fuel pyrolysis machine, DOING has a mature engineer team and abundant project experience to customize suitable machine schemes based on the types and states of pyrolysis raw materials. Also, DOING will help you consider other points to help you successful project carrying based on your processed feedstocks, such as different feeding methods, safety devices, PLC intelligent control system, etc.

PLC control system for pyrolysis machine

Take the recent popular oil sludge raw material as an example, DOING has cooperated with many customers on our waste to fuel pyrolysis machine to process oil sludge, and our sales manager can recommend appropriate feeding methods, as well as special anti-sticking wall solutions, so as to avoid the unstable operation of equipment caused by sludge sticking on the inner wall of the reactor or factors affecting the service life of the reactor. And if you want to make more precise control over temperature, DOING can also provide the PLC control intelligent system for you.

All in all, if you also have some feedstocks for pyrolysis, just feel free to contact us directly, our engineer will provide an overall machine scheme for you.
