ENERGY FROM WASTE – THE BURNING ISSUE

OPPORTUNITY FOR SALTBURN COMMUNITY TO DEBATE PROPOSED INCINERATOR

The Cyclerval oscillating kiln reuses residual waste as a basis for heat and power.

A long established technology – already operational in France, Belgium, the USA and the UK – the design of the kiln's combustion chamber is a way of producing heat and power from residual waste in an efficient and reliable way that eliminates and minimizes harmful by-products.

When residual waste is burned it produces hot combustion gases. These hot gases are then used to generate steam through a boiler for the production of electrical energy and then reused for heating industrial facilities, office blocks and housing estates.

The tapered cylindrical shape of the combustion chamber (where the residual waste is burned), its oscillation (which keeps the waste constantly moving) and directed flows of hot air, combined with the specially designed insulating refractory lining (which prevents heat from being lost and keeps the kiln lining hot) mean that high temperatures are easily maintained.

Maintaining a high temperature means that very few hazardous by-products, such as dioxins, furans and carbon monoxide are formed in the process. In keeping with strict SEPA and EU regulations waste gases are monitored and where necessary treated. As well as minimising environmental impact this also means that the plant can produce energy more efficiently.
The technology is designed to reduce and reuse residual waste. The solid waste left over from the process, bottom ash, is of a high enough quality to be recycled. At the Cyclerval plant in Pontenx, Southern France, 100% of bottom .ash is recycled for road base and path constructions purpose. Metals passing through the kiln are recovered and recycled.
