konus has developed a combustion system which enables economic energy generation from waste products - the kkv system. this system is of underfeed design with the fuel being transported into the burning chamber by a feed screw. the special features of this system are the round combustion chamber and tangential air nozzles which cause vertical combustion. depending on the fuel type, a system of secondary and tertiary air nozzles provides air to the grate area these unique construction characteristics, in particular the high, constant convection properties, of the round burning chamber, allow even traditionally difficult fuel, up to a moisture content of 150 on dry basis depending on the grate configuration, to be burned efficiently. the variety of fuels suitable for the kkv system ranges from wood wastes (e.g. shavings, chips, sander dust or bark), to bagasse, peanut hulls, cotton and coffee wastes. the konus product line encompasses thermal oil heaters for pressureless process heat up to 320 c, warm and hot water heaters for temperatures up to 200 c, and low pressure steam systems. the kkv systems range in unit capacity from 1.6 to 32 million btu per hour. modular construction of these systems keeps delivery and installation to a minimum. the burning chamber can be insulated prior to shipment.
