The Cogeneration or CHP Directive

This refers to the ”’Directive on the promotion of cogeneration based on a useful heat demand in the internal energy market and amending Directive  92/62/EEC”’, officially 2004/8/EC and popularly better known as the ‘CHP Directive’ It is a European Union directive for promoting the use of cogeneration in order to increase the energy efficiency and […]

Owning and Operating Costs of Waste and Biomass Power Plants

Claverton Energy Conference, 23/24/25th October 2009

Dave Andrews, DAEC

Here are some broad brush head line figures for the owning and operating of a particular kind of advanced staged combustion power plant, obtained from a leading manufacturer, suitable for biomass, waste materials and waste wood. The process is essential combustion, but is referred to as gasification / combustion, meaning the material is first charred on a grate, with the off syngas being burnt in a separate adjacent and low level refractory chamber. The char is then burnt at a later stage as it moves down the great. This leads to greater burn up of fuel and lower emissions. The syngas combustion is maintained within the ceramic, and special gas flows prevent the contaminants in the gases fouling and degrading the ceramics.

ADRECS – How To Rapidly Convert The Central Deserts Of China To Agricultural Regions Producing Huge Amounts Of Renewable Energy For Europe

This article describes a novel concept using existing technology to very quickly a) control the desertification and sand drifts b) enable the establishment of plant species c) the construction of wind farms or CSP connected to Europe by either a lengthy HVDC transmission system, or the local production of ammonia which can readily be transported to eg Europe / USA and easily used as a vehicle fuel d) the construction of a vast area of seawater greenhouses using sea water pumped thousands of miles to be desalinated by solar energy to allow the production of food and or energy crops. (Contrary to what some ill-informed people claim this does not use a huge amount of energy compared to other national uses) e) unlocks the massive potential for carbon sequestration via organic matter in soil

KIV – Biomass and waste to energy district heating and power generation plants

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.
