KIV commenced the commissioning a new gasification EfW CHP and district heating scheme in September 2008. The plant has been designed to environmental standards above and beyond the EU Waste Incineration Directive (WID), which also incorporates Best Available Technique (BAT), lodged with the EU BREF documents office. The plant will be an EU ‘showcase’ project, which incorporates a presentation room for coach parties of visitors.
Approximately five years ago, KIV commenced a joint development for the gasification EfW CHP plant with Celje town council. The plant has an 18MWth input capacity for <38,000 tpa of a mixed fuel (80% RDF + 20% Sewage Sludge), with an average CV of 13.6MJ/kg, based on a guaranteed 8,000 hrs/annum availability. The scheme is connected to an existing District Heating scheme, which has a 110oC flow temperature. The scheme is ‘heat led’ and therefore produces a reduced amount of gross power at 2.1 MWe. If the scheme was ‘electricity led’, it would produce 3.8MWe of gross power.
The concept is a town sized solution, for the safe disposal of local residual waste (RDF), mixed with sewage sludge. The energy released from this mix of waste is returned locally to heat residences. This
means the plant is extremely carbon friendly, with minimal waste movements, unlike large mass burn incineration systems.
KIV EfW and biomass plants are designed on the basis of over 30 years of experience of their proven step grate and 17 years of their patented gasification technology. The systems are efficient, robust, reliable and overall bankable, ensuring return on investment, which is increasingly important for the larger EfW and biomass power generation projects.
KIV’s largest single Waste Incineration Directive (WID) compliant gasification train is capable of handling up to 55,000 tpa of waste (depends on net CV of waste / fuel), therefore two ‘trains’ (50MWth input), can dispose of up to 110,000 tpa of waste on a single site, which would produce between 10 and 14 MWe. Typically, an EfW plant of this throughput, 110,000 tpa/annum, with civils and buildings would cost less than £50M. A front end processing plant would be additional.
Besides these larger plants, KIV design, manufacture and install smaller WID compliant and clean biomass CHP or steam/hot water only plants down to 1MWth. This means that ‘on-site’ bespoke EfW solutions are available for Commercial and Industrial sites, to simultaneously reduce waste disposal costs and fossil fuel bills.
Development at KIV is underway to ensure that future plants are capable of meeting the recent changes to legislation, i.e. EU Waste Framework Directive (WFD), to ensure the plant has a high electrical efficiency to be classed as a ‘Recovery’ plant and not as a ‘Disposal’ plant, and also to comply with the UK Gov. change to confirm that >4MJ/Nm3 syngas is being produced, this will then lead to the plant being classed as Advanced Gasification, which will place the plant in the two ROC’s banding for the biomass percentage.

Richard – thanks for this.
Can you give us some figures on roughly :
The total CAPEX to install the plant.
CAPEX to install the pipework to the houses.
The population served with heat
No dwellings served with heat
The peak heat demand
What the emission actually are
Construction lead time
Smallest viable plant size
YOUR WEBSITE IS VERY USEFUL TO ME
I must agree completely, but if a call is formed, don’t we still need to go ahead? I agree, but what are the choices? Good articlethough. Thanks.
