There are many applications for clean steam throughout the industrial processing, food and beverage, pharmaceutical, institutional, electronics, and healthcare fields. Clean steam is produced by a secondary generator using a controlled feedwater source free of contaminates that may be detrimental to the process or activity where the final steam product is used. An example, applicable in many areas, is the humidification of supply air in a plant, commercial, or institutional building. In some humidification designs, steam is injected or dispersed directly into the air flowing through a duct delivering supply air to occupied spaces. The steam, absorbed by the supply of air and increasing its moisture content, becomes part of the atmosphere in the human-occupied space. Carryover of commercial boiler feedwater chemicals or other potential contaminates will adversely impact the air quality. A secondary clean steam generator, heated with steam from the central plant boiler and utilizing properly treated or purified feedwater, delivers steam to the humidification system free of unwanted substances.
The application of a familiar commercial boiler as a secondary generator is generally not a solution to the production of clean steam. In most instances of clean steam generation, the feedwater is treated and purified to a condition that makes it aggressive to the range of steel types used in the fabrication of boilers intended for common industrial use. Clean steam generators need fabrication from stainless steel or other metals that can withstand the corrosive effects of purified water.
