the advantage of water tube boiler for fire tube boiler
Molten salt heaters use molten potassium nitrate and sodium nitrite as heating media. Molten salt heater will heat the powder salt over the melting point until the viscosity of the molten salt allows circulating pump works, after the whole system is under circulating condition, then feed then into the thermal fluid heater for further circulating rising temperature to make it to be recycling used. Normal media working temperature is 400-550℃, top working temperature could reach 600℃.
3. Fire tube boiler can be used in small scale industries. 4. Fire tube boiler is relatively cheaper than water tube boiler. Disadvantages of fire tube boiler: 1. From the furnace combustion side, required time to fill water is longer than to increase temperature and pressure. 2. The efficiency of heat transfer (heat transfer efficiency) is bad
The design of the current boiler products has been in place for well over 30 years. However, both market conditions and a demand for furnace chambers that will be compatible to low NOx combustion systems have resulted in a need for new, innovative firetube boiler design.
Fire tube boiler is easy to use, clean and maintain. It can be easily used in small scale industries. Fire tube boiler is relatively cheaper than water tube boiler. Disadvantages of Fire Tube Boiler: Steam output pressure cannot be very high since the water and steam are enclosed in the same vessel. The steam received from the fire tube boiler
A fire-tube boiler is a Packaged boiler in which hot gases from a fire pass through one tube or more tubes running through a packaged container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.
First of all Water Tube Boiler and Fire Tube Boiler are completely opposite for its structural designs. In Water Tube Boiler water will be heated inside the Boiler Tube and heat will passes around the Tubes. Generally heat passes from the boiler Furnace or Combustion Chamber to around the Boiler Tube.
Benson Boiler | Construction and Working Principle of Benson Boiler; Water tube boiler: The boiler in which the water is present inside the tubes and fire or hot gases surrounds these fire tubes. The examples of water tube boilers are a La-Mont boiler, Benson boiler, Stirling boiler, Babcock and Wilcox boiler, Yarrow boiler and Loeffler boiler
The boiler is divided into two main types. One is known as fire tube boiler and the other one is known as water tube boiler. These boilers is largely used in power development and other industrial like sugar industries, cotton industries etc. for steam generation.
Vertical boiler's wiki: A vertical boiler is a type of fire-tube or water-tube boiler where the boiler barrel is oriented vertically instead of the more common horizontal orientation. Vertical boilers were used for a variety of steam . Chat Online

Therefore water tube boilers can develop higher pressures than the fire tube boilers. 3. Higher rate of evaporation: In water tube boilers, water is contained in a large number of small diameter tubes; therefore the heating surface of a water tube boiler is more than that of the fire tube boiler.
Water tube and fire tube boilers have totally opposite structural designs.The water to be heated in water tube boilers is enclosed inside the boiler tubes. The hot combustion gases exhausted by the burner keep circulating around the tube surfaces.
