2.12.1 Replacing the Granulate

Fig. 2-81 Pyrolysis Unit

The pyrolysis unit is located at the

back of the system at the oven inlet.

Note!

The system must be cooled down before replacing the granulate, because

the granulate has a temperature of at least 500° C when the system is

running.

3. Remove the white insulation

which now becomes visible (see

Fig. 2-83). The cover of the py-

rolysis unit becomes visible as

well.

4. Loosen the nuts on the granu-

late container (see

Fig. 2-84) and lift it out along

with the granulate (see

Fig. 2-85). It must be assured

that the nuts and the washers

do not fall into the pipe connec-

tion.

5. Remove the screws which se-

cure the grate and lift the grate

and Gauze Filter off (see Fig. 2-

86).

6. Inspect the granulate for con-

tamination by breaking open

several pellets. If the granulate

is dark colored all the way

through, it has become saturat-

ed and must be replaced.

7. Fill the container with new gran-

ulate under dust-free condi-

tions.

8. Apply copper paste to the

threads. Copper paste is heat-

resistant up to 1000° C.

If the old nuts need are no lon-

ger usable, do not replace them

with stainless steel or zinc plat-

ed nuts.

9. Reinstall the granulate contain-

er by following the above in-

structions in reverse order,

insert the insulation and the

seals (or replace if damaged)

and secure the cover with the

screws.
