Owning and Operating Costs of Waste and Biomass Power Plants
Posted by: | CommentsClaverton 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.
This is a big issue in conventional plants since refractories have to be replaced every few years due to chlorine attack.

FOE Cymru were gutted by the recent consent given to the 2GWe CCGT Npower application at Pembroke power station site. Its on the south side of the Haven and will dump 9 TWh/y into the waterway (capturing 6 TWh/ would have been enough to heat 330,000 homes rising to 500,000 if insulation programmes reduced annual consumption to 12 MWh). Worse, the two new LNG terminals are a few miles away but on the north side of the Haven and will require about 3 – 6 TWh/y of low grade heat to re-gas the LNG ! They say putting CHP pipes under the 1 mile water way is not feasible (to their lazy mindset) but they will be putting a gas pipeline under the waterway to fuel the CCGT. – a correspondent writes.

Almost new gas engine built to operate on biogas generated from a gasification process from woodchip. The project is for The Highland Council in Wick who are carrying out an assessment of possible options for heat supply.
The engine specification is as follows:
- Engine model Jenbacher JMS 620 GS-S.L. (1.5MWe)
- Gas analysis: 15-20% H2; 3%CH4;15-20% CO; 10% CO2; 40-50% N2
- 43 starts
- Generated 6.4MWh
- Operated for 13 hours

NATURE magazine promotes CHP, CHP/DH and Rankine cycle turbine for energy recovery.
Posted by: | CommentsNature this month carries a very good article on using high temperature waste heat to generate power in a Rankine cycle, and strongly advocates the use of CHP and holds out Denmark as an example.
