Corrosion in boilers - Lenntech

Corrosion is a relevant problem caused by water in boilers. Corrosion can be of widely varying origin and nature due to the action of dissolved oxygen, to corrosion currents set up as a result of heterogeneities on metal surfaces, or to the iron being directly attacked by the water.

How do Boilers Work & What is their Use on Ships? - Bright

A basic boiler is a machine with the simplest arrangement of the internal parts. The main job of a boiler is to make high pressure steam. The feed water supplied to the boiler drum utilizes the heat of the energy released by burning the fuel. This energy of the burning fuel is stored in the form of steam with high temperature and pressure.

Boiler Water Conductivity Measurement Fundamentals

A relatively high frequency (for example 1 000 Hz) is necessary to avoid polarization at the high conductivities of boiler water. Whilst the boiler water conductivity is converted to a resistance through the probe, it cannot be measured using a simple dc resistance meter.

Boiler Types and Classifications - Wiki - odesie by Tech

Boiler Types and Classifications. There are two general types of boilers: ''fire-tube'' and ''water-tube''. Boilers are classified as "high-pressure" or "low-pressure" and "steam boiler" or "hot water boiler."Boilers that operate higher than 15 psig are called "high-pressure" boilers.
