Improved ash removal from BioMass plant
Solids handling equipment specialist, Ajax Equipment has supplied 24 plug screw feeders to BioMass Engineering to handle ash removal from a gasification based renewable energy plant
The plug screw feeders are used to prevent oxygen entering the furnace as ash is removed from the process gasifier and filter Owned by O-Gen UK, the 4.5 MWe reclaimed wood fuelled biomass gasification plant produces energy from wood chippings, forestry wood and energy crops, which will be exported to the National Grid

Increasing leather process chemical production
An innovative twin screw feeder developed by solids handling equipment specialists Ajax Equipment is set to significantly boost Leather Process Chemical productivity at Clariant Chemicals
It consists of a three stage process: fuel preparation (size and moisture), wood gasification and finally power and heat generation.
Ash is produced during the gasification which has to be removed from the gasifier.
Ash in the gasifier exhaust gas is captured by filters which also has to be removed for recycling into a useful by-product.
Maintaining an oxygen-free gasifier is essential.
BioMass Engineering had tried using traditional screw feeders and airlock hoppers to remove and store the ash, however, these allowed ingress of oxygen into the process.
The company contacted Ajax Equipment to assist in overcoming the problem.
Ajax devised a plug screw feeder solution to remove the ash from the gasifier and filter.
The screw densifies the ash as it leaves the screw to create an impenetrable barrier.
"Adopting a plug screw feeder allows BioMass to run the process continuously, the ash being removed without oxygen entering the system," said Eddie McGee, technical director, Ajax Equipment.
Jim Campion, managing director, BioMass Engineering, commented, "The way Ajax Equipment approached the problem, and worked with us to find the right solution for removing the ash, has allowed us to improve the overall process reliability".
This Stoke-on-Trent renewable energy plant is set to come into operation mid 2008.
