Operational mode


ECOL­O­GIST PRO­FORTE is the PRO­BAT ex­haust air clean­ing sys­tem for max­i­mum clean­ing ef­fi­ciency. The ex­haust gases pro­duced dur­ing roast­ing are piped through a ce­ramic bed which has an in­ter­nal tem­per­a­ture of 900 to 1,100 °C. This en­ables the ther­mal com­bus­tion of the emis­sions with­out gen­er­at­ing the ni­tric ox­ides as­so­ci­ated with catal­y­sers. The ce­ramic bed is heated up elec­tri­cally, then its tem­per­a­ture is main­tained by the ex­haust gases’ re­ac­tion (or by feed­ing gas in through noz­zles in standby mode). The di­rec­tion of flow is cycli­cally re­versed to keep the high tem­per­a­ture in the mid­dle of the bed. This re­sults in ther­mal ef­fi­ciency of ap­prox. 95 to 98 %. As an op­tion, a buffer tank can be added to the sys­tem to catch the un­cleaned ex­haust air which would oth­er­wise es­cape dur­ing the changeover. Once the di­rec­tion of flow has been re­versed, this air is then in­cor­po­rated into the clean­ing process again. The lim­its stip­u­lated in Ger­many’s air pol­lu­tion con­trol reg­u­la­tions are re­li­ably ob­served, whether a buffer tank is used or not.
