Lay out design of an incineration plant

The building for the rotary kiln incinerator does not require much floor space. The main area is taken by waste storage and - handling. Waste handling means: loading and offloading waste collection trucks, weighing and registering, prepare the waste before being incinerated and shift it to the incinerator. Also,space and logistics must be provided for ash handling and evacuation.

The building design must also foresee the required space for servicing all technical equipment,including a spare parts store.  The storage building must be able to store waste for 4 weeks, this a buffer in case of shut-down.

The waste storage building should ideally be suitable to contain a waste buffer,enough for a four weeks operation of the plant.

Example: Buildings for a 8000 ton/year rotary kiln plant

This waste incineration site (drawing in attach) covers 5000 m²  on which 2 buildings are erected :

• Incinerator building: 30 m x 20 m and 12 m high
• Waste storage building: 50 x 25 m and 6 m high

The capacity waste storage should be enough for 4 weeks of operation,or in this case,about 667 tonnes. Due to the low density of waste, about 300 kg/m³, the required storage volume will thus be over 2200 m3.

For hazardous waste storage, the regulations on storage of dangerous goods apply :passages and separation zones between different products have to be foreseen,which requires a much larger (up to three times!) floor space.In many cases stacked storage cannot be applied,because of the amorph nature of the waste.

The outskirts of the site shown below, are not large enough to accomodate all the traffic related to operations : ideally it should have about 2500 m² more space.
