Biomass gasification filters P
orvair Filtration Group has expanded its range of high temperature filters with the
introduction of metallic filter elements optimised for biomass gasification. High temperature filtration in
the biomass gasification process is a demanding application. The efficiency of the thermochemical
conversion process and the subsequent emission control are highly important areas in the development of environmentally sound and sustainable technology. Both are highly important for biomass combustion and gasification plant design, operation and economy. Biomass gasification processes are
characterised by the use of increasingly higher temperatures and a contaminant that in some ways is more challenging due to its inherent cohesivity and adhesivity making it more difficult to be removed as a filter cake during in situ cleaning. Proprietary metallic filter material
developments made by Porvair Filtration Group has now permitted these higher
Biomass gasification involves
incomplete combustion of biomass and this results in the production of combustible gases, consisting of Carbon monoxide (CO), Hydrogen (H2 Methane (CH4
). This mixture is called producer gas.
Producer gas can be used to run internal combustion engines (both compression and spark ignition), and can be used as a substitute for furnace oil in direct heat applications. Porvair says It can also be used to
produce, in an economically viable way, methanol – an extremely attractive chemical which is useful both as fuel for heat engines as well as chemical feedstock for industries. Since any biomass material can undergo
temperature duties to be considered and changes to the Pulsejet design now enable biomass gasification filter cakes to be removed more effectively thus ensuring continuous on-service performance.
