ADVANTAGES OF WASTE COMBUSTION

In comparison to pyrolysis and gasification combustion has three good points:

A. Cost of waste incineration is lower (10 times).

B. Capacity of waste incineration is greater (10 times).

C. More efficient waste energy utilization.

- conditions of pyrolysis products burning,

- conditions of pyrolysis products conversion,

- pollutant emissions (gaseous and dust).

DISADVANTAGES OF WASTE PYROLYSIS

The waste incineration installations based on pyrolysis process has several disadvantages in comparison to the combustion processes: :

• less capacity,

• less efficiency,

• more sophisticated,

• more expensive.

APPLICATIONS OF PYROLYSIS-BASED WASTE INCINERATION

TECHNOLOGIES

1. INCINERATION OF HAZARD WASTES

2. PRIMARY STAGE OF WASTE INCINERATION IN SOME TECHNOLOGIES (DUOTHERM).

ADVANTAGES OF WASTE GASIFICATION

1. CONVERSION OF WASTE INTO VALUABLE PRODUCTS.

2. POSSIBILITY OF SYNGAS PRODUCTION (H2AND CO).

3. SAFE LANDFILL OF ASHES.

DISADVANTAGES OF WASTE GASIFICATION

Similar like for pyrolysis:

• very sophisticated,

• small capacity,

• very expensive.
