The space formed between the outer cylinder and the inner cylinder has a smaller channel area than the interior of the inner cylinder, and a swirling flow along a guide formed on an outer circumferential surface of the inner cylinder and a substantially linear flow in a longitudinal direction of the outer cylinder and the inner cylinder are applied to the cooling water returned to the base end through the space formed between the outer cylinder and the inner cylinder.

Abstract: A combustion device in the form of an elevated fixed-grate that includes arcuately shaped solid refractory brick with ribs placed thereunder so as to allow horizontal air flow for fuel combustion. The brick are arranged atop one another in a stacked concentric configuration that forms a central fuel passageway and allows cascading of a fuel pile throughout the combustion stages. The device provides the benefit of proper de-ashing online while distributing the underfire air radially around the fuel pile. The elevated design of the bricks allows the air to be evenly distributed throughout the fuel pile and further allows the isolation of overfire and underfire air. Segregating overfire and underfire air in an evenly distributed manner allows the burner to combust a wide range of fuel moisture contents without modifying the mechanical components of the burner.

Abstract: A secondary lint trap couplable between a laundry dryer and a building-embedded vent duct. The trap has an elongate housing. Aligned inlet and outlet apertures are formed in bottom and top sides of the housing's rearward ends. A tray is removably insertable within the housing. A screened aperture in the tray is aligned between the inlet and outlet apertures when the tray is inserted within the housing. The housing is mountable above the dryer such that the inlet and outlet apertures extend rearwardly of the dryer. This facilitates coupling of the dryer's exhaust outlet to the inlet aperture through one 90° elbow via a first short, substantially straight, elbowless conduit; and facilitates coupling of the vent duct to the outlet aperture through one other 90° elbow collar via a second short, substantially straight, elbowless conduit.

Abstract: A control system for dryers in which the rotation speed of the motors are changed through frequent on/off connections to the electric power line. In accordance with the invention this task is solved by interrupting the electric power driving the electric motor for short periods in such a way that the motor does not come to a complete standstill or remains at a constant speed below the maximum speed. The motor power interruption or application is based upon readings of sensors reading dryer parameters other than the actual speed of the motor being controlled.

Abstract: In a sludge treatment installation, a movable carriage is arranged transversely above a work surface of a floor. The movement of the carriage by longitudinal translation over the floor is initiated by a first drive shaft carrying a toothed wheel meshing with a drive chain. A second chain helps to guide the carriage. On the carriage is provided a rotary turning tool which engages in the sludge. Driven in rotation by a second drive shaft independent of the first, it includes pairs of semi-cylindrical paddles fixed substantially symmetrically by one of their edges on either side of a shaft driven by the second drive shaft. The two paddles in each pair of paddles are asymmetrical as a result of having different radii, with a difference at least equal to about 5%. Forced ventilation acts directly on the paddles.

Abstract: An inside of an incinerator body into which sludge is fed is divided into a lower portion, a portion above the lower portion, and a top portion in a height direction. The lower portion serves as a pyrolysis zone for supplying fluidizing air having an air ratio of 1.1 or less together with fuel to thermally decompose the sludge while fluidizing the sludge. The portion above the lower portion serves as an over bed combustion zone for supplying only combustion air having an air ratio of 0.1 to 0.3 to form a local high temperature place to decompose N2O. The top portion serves as a perfect combustion zone for perfectly combusting unburned contents. The quantity of N2O generated during sludge incineration can be drastically reduced while maintaining the use quantity of auxiliary fuel at the same level as that of a conventional incineration method.
