The majority of maintenance issues and breakdowns for steam equipment are due to sediment buildup and calcification in the boiler component of the unit. A proper water filtration system for your food steamer can prevent unwanted buildup of sediment, cysts, lime, calcium, and chlorine taste and odor to keep your machine running in peak condition.Learn More
4. Economizer. Originally cast iron to resist conversion from 0. in boiler water. Now low carbon steel with de-aeration of feed- water. 5. Air Heaters. Mostly low carbon steel but low temperature parts may be stainless; ceramic and even glass has been employed. 6.Learn More
FAN—Blower on a locomotive boiler. (Standard practice is to issue these on tissue paper to facilitate the making of carbon copies) PETTICOAT—Portion of the exhaust stack that guides exhausted steam into the stack proper. When this becomes displaced, the spent steam goes back through the flues, cutting off the draft from the fire Learn More
- 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.Learn More
