Boilers | Inspectioneering

Boilers are one of the most fundamental systems of a refinery or chemical processing plant. They are literally the pieces of equipment that keep the plant up and running. Most industrial boilers fall into two broad categories of boiler types: Fire-Tube Boilers and Water-Tube Boilers. In fire-tube boilers, hot gas passes through one or many

The Importance of Boiler Water and Steam Chemistry

The Importance of Boiler Water and Steam Chemistry. Steam Purity. Purity or chemistry requirements for steam can be as simple as a specified maximum moisture content, or can include maximum concentrations for a variety of chemical species. Often, for low pressure building or process heater steam, only a maximum moisture content is specified.

Water Tube Boilers | Spirax Sarco

Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be …

How a Water Tube Boiler Works | Miura America

With the water tube design, the water is surrounded by heated gases rather than the other way around. The hot gas moves from the firebox into the boiler's main chamber. In some cases, the gas will hit the back wall of the boiler and then bounce back toward the other end of the boiler. This creates a superheater effect inside the boiler, which
