| Allington Energy recovery plant (incineration) | Stein Pyrolysis Unit in combined cycle for same fuel |
|---|---|
| 500,000 tons of residual waste from all over Kent delivered to fuel transfer stations and then taken by truck to the mass incinerator | Six plants located next to fuel transfer stations |
| Latest Lurgi fluidized-bed technology, the leading-edge technology of this type, that is WID compliant | Pyrolisis process (no chlorines or dioxins generated). Also WID compliant but without expensive abatement requirements |
| Generates some 34MW net power supplied to the grid | Each plant will generate 9MW totalling 54MW for the grid |
| Total investment in the plant over £150,000,000 (£4,400,000/MW) | Total investment for all six plants is 6 x £20,000,000 = £120,000,000 (£2.2M/MW) |
| Deliveries by almost 300 trucks per day with an estimated round trip of 35 miles (10,000 truck miles per day) | No truck movements as the plants are at the fuel transfer sites |
| 50 jobs created | 120 jobs created |
| 84 acres of of land use | Each plant will require approximately 2.5 acres of land use i.e 15 acres of land areas |
| 80m tall chimney required | Plants require 4 x 15m tall chimneys |
| Bottom ash has dolomite added and is recycled | No back end cleaning required |
| Fly ash has lime and activated carbon added to clean up the chimney emissions | Fewer chemicals required giving lower operating costs per MW |
| Expected emissions are as follows: dioxins - 0.05 ng/Nm3(limit is 1.0); SO2 - 15 mg/Nm3 (limit is 300); NOx - 325 mg/Nm3 (limit is 350); and CO - 4 mg/Nm3 (limits 100). HCl, HF and heavy metal particulates are all well below established limits | Expected emissions are as follows: dioxins - nil (limit is 1.0); SO2 - 15 mg/Nm3 (limit is 300); NOx- 345 mg/Nm3 (limit is 350) and CO - 80 mg/Nm3 (limits 100); and almost no HCI, HF or heavy metal particulates |
