[QUOTE="MGE90D, post: 913866, member: 7191"] It really depends on the drier. A 12t GT would be at the lower end of air throughput and a 50t Mecmar. But generally speaking I would say anything up to 300kW is unlikely to be cost effective with a mobile drier. The aim of the game is to burn a high proportion of biomass compared to diesel/LPG. There is a trade off, drying at lower temperatures will reduce the amount of oil/gas used in comparison to biomass but will extend drying times. To put it into context I work for McArthur Agriculture and we specialize in batch driers. It is in my interests to identify commercially viable operations as we can provide heat exchangers tailor made to different driers (mobile or static or floor). However, there is a very slim set of parameters where it works. In general the biomass for drying grain concept (in any type of drier) is nowhere near as commercially viable as one would be led to believe from the media coverage. And the situations where it does stack up you are dependent on the guaranteed payments. Personally I don't believe anything is guaranteed when it is coming ultimately from the government. I know that all sounds very negative, it is possible to make it work but I keep finding my customers who have been given extremely questionable sales pitches for using the biomass by people who know nothing about drying grain, frankly its getting a bit ridiculous.
