ABSTRACT:
An exceptionally long, segmented, high-altitude flue of flexible, light-weight material suspended vertically at its upper end from a gas-filled balloon and including at its lower end an open-bottomed hood. The hood segment tapers upwardly from an extremely large bottom opening to its junction with a stack segment. The stack segment is of uniform cross-section throughout and is formed from a plurality of tubular sections permitting the stack to be adjustably raised to any desired height. For field burning purposes, the stack and hood segments are made of a fire-proof material and the bottom hood opening is surrounded by a refractory, rigid-walled enclosure elevated above ground level by skid-type supports. Refire grids of refractory material are provided within the apparatus to minimize the escape of incompletely combusted particulate matter suspended in the hot gases which rise through the hood and stack. Cables connecting both the balloon and the rigid-walled enclosure to winch-equipped ground vehicles are utilized to control the altitude of the stack and the position of the hood enclosure and to advance the enclosure over the ground.
