how much is the water quality oxygen content of steam boiler


Types of Heating Systems | Smarter House

In steam boilers, which are much less common in homes today, the water is boiled and steam carries heat through the house, condensing to water in the radiators as it cools. Oil and natural gas are commonly used. Instead of a fan and duct system, a boiler uses a pump to circulate hot water through pipes to radiators.

Water Handbook - Water Sources, Impurities and Chemistry

WATER AS A SOLVENT. Pure water (H 2 0) is colorless, tasteless, and odorless. It is composed of hydrogen and oxygen. Because water becomes contaminated by the substances with which it comes into contact, it is not available for use in its pure state. To some degree, water can dissolve every naturally occurring substance on the earth.
