Ceramic Filters for Biomass Wood Fired Boilers

CASE STUDY 18. Ladyloan School Scotland In 2007.

Glosfume was asked to reduce the emissions from a wood fired biomass boiler at Ladyloan School in Scotland. Both the local authority but more importantly the parents' were concerned about how the high level of PM10 and PM2.5 particles would disperse in and around the playground area.

Ladyloan school was our first ceramic filter installation to control both PM10 and PM2.5 emissions from a biomass wood fired boiler. From this we then developed our BMF range of filters to control boilers rated from 50kW to 10MW.

Glosfume’s success in removing PM10 and PM2.5 at Ladyloan resulted in a Rushlight Award for Air Pollution Technology. This helped establish Glosfume's ability to remove these ultra low levels of particulates.

Most major wood fired boiler manufacturers now use BMF filters which enables biomass wood fired boilers to be used in areas of poor air quality.

As at October 2013 Glosfume has installed over 250 BMF filters, including a 2MW boiler at a French tomato farm where the boiler contaminated neighbouring strawberry farm . Glosfume resolved the problem. The Tomato farm has now placed a second order to control the second boiler.

With complete combustion, without formation of tars, the expected life span for the ceramic elements will be up to 5 years.

Typical emssions: Ladyloan benefits from emissions levels as low as 1.5g/GJ (typically 0.5)

To qualify for RHI funding the emissions need to be 30g/GJ
