Boiler Engaged in Thermodynamics

Boiling water to quality in the tubes is undesirable because water vapor has different heat transfer characteristics than liquid water. This is referred to as low water condition. In low water conditions, the boiler does not receive the amount of feedwater needed to keep it running at safe conditions.

Which Heat Exchanger Is Best? The Three Main Types

The shell and tube heat exchanger in the photo above has about twelve times the efficiency than a hypothetical single-tube heat exchanger of the same size. However, there is a disadvantage to smaller tubes – if the fluid in your application is very viscous or has particulates, it can foul up the tube and undermine the heat transfer process.

Different Types of Radiator/ Boiler Systems Hunker

Next to forced-air heat, a boiler-and-radiator system is the most common type of heating system in cold-winter climates. All boiler systems use hot water to heat the home. There are two main types of boilers—steam and hot water (also known as hydronic)—and many more types of radiators or heating appliances, the units that transmit the heat into the rooms.
