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 tolerated for the same stress.

Difference Between Fire Tube Boiler and Water Tube Boiler

Fire Tube Boiler. It is a boiler in which the hot flue gases is present inside the tubes and the water surrounds these tubes. As fire is present insides the tubes, hence it is called as fire tube boiler. The steam produced by these boilers have pressure of about 25 bar and that's why they fall under the category of low pressure boilers.

Boiler Basics and Types of Boilers, Differences

A boiler is a steel pressure vessel in which water under pressure is converted into steam by the application of combustion. In other words, it is simply a heat exchanger which uses radiant heat and hot flue gases, liberated from burning fuel, to generate steam and hot water for heating and processing loads.

Boiler modulation - is more better? - HPAC Magazine

Boilers are rated on their thermal efficiency, which is simply the ratio of the chemical energy added to the boiler over the energy added to the boiler water. As more heat is transferred from the hot gas into the boiler water, the thermal efficiencies increase and the exiting (flue) hot gas temperatures decrease.

The Temperature in Your Boiler and the Dangers of Overheating

If a boiler has reached 220°F, a sudden drop in pressure could cause the tank to burst. Overheating also is the main cause of leaking. When the water temperature in the boiler becomes too high, it increases the water pressure throughout the system. This will cause breaks to begin occurring at valves and connectors.

Guide to Managing the Condensate for Condensing Water Heaters.

The condensing process is achieved by passing the piped hot flue gases through the cooler return water flowing back into the boiler. Flue gas starts to condense when it drops below its dew point of 55°C. This is why condensing boilers are designed to accommodate a return water temperature of 54°C or less.
