The heat from the hot gases transfers through the walls of the tubes and heats the water. In a water-tube boiler, the water is in the tubes while the fire is external to the tubes. The hot flue gases pass around and between the tubes, heating the water and then out the boiler vent.Learn More
Feed-water purity requirements therefore can vary widely. A low-pressure fire-tube boiler can usually tolerate high feed-water hardness with proper treatment while virtually all impurities must be removed from water used in some modern, high-pressure boilers. Only relatively wide ranges can be given as to maximum levels of alkalis, salt, silica Learn More
Aug 19, 2019 · Once again, when the water is boiled, steam is generated and moved downstream. A water-tube boiler is more thermally efficient than a fire-tube boiler, but they are more complex to construct and the quality of the water can be a limiting factor. The water may need filtering to operate most effectively.Learn More

A cost saving can be achieved with respect to chemicals - this argument becomes increasingly valid on large water-tube type boilers where flowrates are high, and low TDS levels (< 1 000 ppm) need to be maintained in the boiler feedwater. Chemicals added to control the oxygen content of the boiler water will themselves require blowing down.Learn More

Boiler water carry-over is the contamination of the steam with boiler-water solids. Bubbles or froth actually build up on the surface of the boiler water and pass out with the steam. This is called foaming and it is caused by high concentration of any solids in the boiler water. It is generally believed, however, that specific substances such as alkalis, oils, fats, greases, certain …Learn More
The trays are placed in each drum of a water tube boiler, or on the top flues of a fire-tube unit. All manholes, handholes, vents, and connections are blanked and tightly closed. The boiler should be opened every month for inspection of the desiccant. If necessary, the desiccant should be renewed. Wet StorageLearn More
Difference Between Fire Tube Boiler and Water Tube Boiler . Since fire is inside the tubes and hence it is named as fire tube boiler.
