OSHA Technical Manual | Occupational Safety and Health
- Direct steam-type humidifiers inject boiler-generated steam directly into the air stream. These systems normally operate above 70 degrees C (158 degrees F), and Legionella cannot survive at that temperature. - Atomizing humidifiers use mechanical devices or pneumatic air to create a water mist that evaporates into the air stream.

Consulting - Specifying Engineer | Basics of hot water
Sep 18, 2020 · Hot combustion gases typically turn up and toward the front of the boiler then back toward the back, similar to a three-pass fire-tube boiler, but instead of the gases passing though tubes, the gases pass through extended surface gas channels on the exterior of the castings. The water is contained inside the castings.
