An atomizing spray dryer employs one or more stages defined by ultrasonic transducers in close proximity to a liquid feed opening forming a path of an atomization flow for producing uniform droplets from a close tolerance with the transducer. The atomization flow exits a gap between the transducer and an outer edge of the opening, such that the passed liquid is responsive to an oscillation of the transducer for forming the droplets. A conical or other suitably shaped transducer engages a substantially round liquid feed opening. Subsequent stages may include a circular, ring, or other suitable shape aligned to receive the atomization flow from a circumference of the conical base, or may also take any suitable shape, preferably to receive droplets directed by the first stage.

Methods and systems for treating wood byproducts, the method comprising the steps of: (i) providing a first quantity of wood byproducts in a first location; and (ii) exposing the first quantity of wood byproducts to ozone at a first concentration for a first time period, wherein the first concentration is configured to decrease the release of carbon monoxide from the first quantity of wood byproducts.

Disclosed is a slurry drying plant (1) comprising a slurry extruder (3) including a slurry inlet (2) and conveying means (4) arranged to convey the slurry through the slurry extruder (3) and force the slurry out of a plurality of exit openings (5) of the slurry extruder (3) to form a plurality of slurry strings (7), wherein the slurry strings (7) are forced out into a drying chamber (8) in which the plurality of slurry strings (7) is dried. The slurry drying plant (1) further comprises slurry heating means (6) comprising flow means for passing superheated steam past the slurry strings (7) in the drying chamber (8), and inlet pressure detection means (9) for detecting a slurry inlet pressure at the slurry inlet (2). The slurry drying plant (1) also comprises control means (17) arranged to control the conveying speed of the conveying means (4) in response to the slurry inlet pressure. Furthermore, a method for drying slurry and use of a slurry drying plant (1) is disclosed.

Insulated ovens include an oven entry enclosure having a quick cool-down fan and damper, a direct-fired, forced draft combustion chamber, a converging enclosure at a distal end of the chamber, an oven exit enclosure having an exhaust fan, and oven cool-down doors. Combustion burners form a first heated gas that heats a wet coated continuous metal sheet to form a dried, uncured continuous metal sheet having a first heated temperature. The converging enclosure includes more burners, creating impinging flames that heat the dried, uncured continuous metal sheet, forming a continuous metal sheet having a dried, cured water-based coating having a second heated temperature. During cooling, actuators stop the coated continuous metal sheet upon receipt of a first signal, stop combustion except for pilot burners, open the cool-down doors and operate the quick cool-down fan to avoid waste. Burners may be relit in a second heating cycle.
