Water Tube Boiler. In this system, a narrow tube filled with water passes through the furnace where the liquid is heated directly. A water tube system produces a lower volume of hot liquid due to its design, but generates a higher level of heat. The liquid heats the house the same way as with the fire tube system. Controlling the System
Mechanisms. Carryover also known as priming is any solid, liquid or vaporous contaminant that leaves a boiler with the steam. In low/medium pressure boilers (<100 bar) entrained boiler water is the most common cause of steam contamination. Both mechanical factors such as boiler design, high water levels, load characteristics and chemical factors such as high solids concentration, excessive
Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships.They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler.
Water drum size is limited to that required to receive the generating tubes, for modern radiant heat boilers with only a single bank of screen tubes and no generating tubes between the drums, the water drum has been replaced by a header and the downcomers fed straight to the waterwall headers.

Water tube boilers. Industrial water-tube boilers work in the opposite way: water is circulated inside the boiler tubes and the tubes are surrounded by hot gases. This type is relatively rare in the UK, but much more common in other parts of the world.
On the other hand in water tube boilers, the water flows inside the tubes and the heat surrounds these tubes. Generally we use the water tube boiler in order to generate the super heated steam like on steam ships etc. the pressure generated on water tubes is always higher the smoke type of boilers.
Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure
Fire-tube boiler: This is a boiler in which the fire or hot gas is present inside the tubes and water surrounds these fire tubes.; Since fire is inside the tubes and hence it is named as fire tube boiler.The heat from the hot gases is conducted through the walls of the tube to the water.
Boiler Types According to tubing methods Ther e are two main types of boiler Fire tube boilers and water tube boilers. Fire tube boilers are those boilers in which fire or flue gases are inside of the tubes and water is on the shell side. Fire Tube Boilers are low capacity low-pressure boilers usually used for heating, processor to produce hot water.

In a fire-tube boiler, the entire tank is under pressure, so if the tank bursts it creates a major explosion. More common today are water-tube boilers, in which water runs through a rack of tubes that are positioned in the hot gases from the fire.The following simplified diagram shows you a typical layout for a water-tube boiler:
These boilers are typically found in colleges, universities, or areas where the system is used to produce steam for space heating or use to create hot water. 3. Scotch Fire Tube Boiler Design. The scotch fire tube boiler design is most commonly referred to as the scotch marine boiler. With this design, the furnace is a big diameter tube located
In a watertube boiler, the heating element acts directly on tubes filled with water, which run through the furnace casing, to produce the needed steam or super-hot water. In a firetube boiler, the heating element produces hot water through a more indirect mechanism. The hot flue gases generated by the boiler's combustion are channeled into
The thermal efficiency of a boiler specifies the effectiveness of the heat exchanger of the boiler which actually transfers the heat energy from fireside to water side. Thermal efficiency is badly affected by scale formation/soot formation on the boiler tubes. Direct and Indirect Boiler Efficiency
Water inside the drum flows down through down comer pipes and distributed by bottom header to water walls. Down comer pipes are outside the boiler furnace while water walls are inside the furnace. Water rises through water wall tubes are exposed to furnace heat. When water rises upside in tubes, a portion of the water is converted into steam
