Digester-biology analysis reaps double-output rewards
Feature
Operators of a crop-fed biogas plant-have watched energy output double in just six months following an overhaul of the digester biology. Based in Consett,County Durham, the 1 MW Generation X AD plant was operating at just 40% efficiency and was suffering from biological instability.
Cheshire biomass plant operational, largest of its kind
Feature
An independent power producer specialising in energy from waste and biomass, Bioenergy Infrastructure Group (BIG), is announcing that one of its largest assets in the UK, Ince Bio Power, has become fully operational after successfully completing its testing phase.
The most effective enzyme preparation to improve flowability?
Feature
Stirrer failures, unstable processes, excessive power consumption and the associated loss of performance are often caused by insufficient flowability of the fermenter media. The application of a new test system for the selection and application of optimal enzyme mixtures to reduce viscosity and substantially improve flowability promises a solution.
The benefits of drying biogas
Feature
With subsidies for renewable electricity generation dwindling, it is more crucial than ever that each part of the AD process is optimised. Not only that, but if water enters a CHP engine it can decrease its efficiency and lead to corrosion, resulting in reduced biogas.
Briquetting: A growing trend for domestic fuel
Feature
Since the beginning of civilization, humans have tried to store and intensify energy. Methods used were as simple as drying, bundling and bailing to compact loose combustible material for fuel making purposes.
Shredding innovations fuel greater biomass potential
Feature
Processing various types of wood “waste” has long been common place. For decades, sawmills have turned wood shavings into useful industry by-products and savvy manufacturers have sought to convert offcuts into woodchips that can be utilised elsewhere.
Trailer loading stations: bad design, good design
Feature
Trailer loading stations are a simple concept. A frame holds an open bottom conveyor over a trailer, which the conveyor fills with material from storage or a live waste stream. They typically employ a screw to distribute the material down the length of the trailer, though drag conveyors are sometimes used.
Efficiently recover heat, capture gases and maximise energy usage
Feature
Whether existing plants are converting from fossil fuel to biomass, or new biofuel — specific plants are being constructed, boilers are required to produce steam that powers other applications.
Slurry pump works wonders, dairy farmer's AD plant
Feature
A Shropshire dairy farmer and anaerobic digestion (AD) operator remembers days when his sorrow turned to joy over what he thought was a faulty flowmeter, only to later discover that the output created by a new slurry pump had sent readings soaring to numbers previously not recorded by the site’s instrumentation.
Biogas plant optimisation, future unlocked
Feature
Governments around the world are seeking to lower greenhouse gas (GHG) emissions in the fight against climate change, to reduce waste to landfill and to increase their utilisation of renewable energy in compliance with international agreements. Consequently, in many countries, subsidies have been made available to encourage the growth of the biogas sector.
