Differences Between Fire Tube Boiler and Water Tube Boiler

Boiler: A Boiler is a closed vessel in which steams are generated (Water to steam) with the help of coal-burning or other fuel substances.. Basically, There are two types of Boiler. Fire Tube Boiler; Water Tube Boiler; Fire Tube Boiler: The fire-tube boiler is the boiler in which fire (hot flue gases) is inside the tube and water is surrounded by them.. Some example of Fire Tube Boiler are:

How Scale Impacts Boiler Performance | Goodway

In a water tube boiler, water runs through tubes that are surrounded by the heating source. Because the water is heated to very high temperatures in this type of boiler, the solids in the water tend to accumulate quickly on the tubes' inside surfaces, causing the same heat transfer problem and related cost increases as occur in firetube boilers.

The High Cost of Boiler Scale - Chem-Aqua, Inc. Water

Because boiler deposits are insulating, the fireside/waterside metal temperatures are much hotter in a dirty boiler than in a clean one. The increased metal temperatures in turn increase the potential for tube overheating and tube failure. Scale deposits in water tube boilers are prone to "slough off" inside the tubes and block water flow.

Drying Refractory in Steam-Generating Boilers - Insulation

Therefore, a power plant must be able to read, monitor, and approximate the temperature of the water/steam inside the boiler wall tubes. The following is an example of a fairly simple dry-out schedule that could be used for drying refractory on the outside of water wall tubes. Raise the water temperature inside the wall tubes or steam drum at

How to Destroy a Boiler -- Part 1

Typical industrial boilers are "natural circulation" boilers and do not utilize pumps to circulate water through the tubes. These units rely on the differential density between hot and cold water to provide the circulation. As the water removes heat from the tubes, the water temperature increases and it rises to the boiler steam drum.

Why Once Through Boiler | Once Through Boiler

The fire tube boiler will run both units (12 ton/h) while Once Through Boiler will run three units (9 ton/h) and have the fourth unit available as required. Since Once Through Boiler can operate from a cold back-up, (water to steam in 5 minutes, while the fire tube boiler can take hours), the fourth unit can be idle until needed.

occur in boilers too. Vibration and noise problems may be encountered as the air / gas / water / steam flow over tube bundles in a power plant. Vortices areformed and shed beyond the wake of the tubes, resulting in harmonically varying forces on the tubes perpendicular tothe flow direction. It is a self-excited vibration.

Boiler Tube Corrosion: How It Starts and How You Can

PITTING The concentration of oxygen in the water is the main cause for severe damage on the water side of boiler tubes by pitting. Water molecules go into the vapor phase at higher temperatures resulting in more water vapor in the air. Cold water holds more air. A deaerator can be used to heat the water with steam to remove oxygen.

Symptoms: Aggressive localized boiler tube corrosion and loss of tube wall.Pits can act as stress-concentration sites which can be initiation points for stress-related corrosion mechanisms. Causes: Oxygen pitting occurs with the presence of excessive oxygen in boiler water.It can occur during operation as a result of in-leakage of air at pumps, or failure in operation of preboiler water
