Fire Tube Boiler: Fire tube or fire in tube boilers; contain long steel tubes through which the hot gasses from a furnace pass and around which the water to be converted to steam circulates. (Refer Figure 2.2). Fire tube boilers, typically have a lower initial cost, are more fuel efficient
A condensing boiler; also known as a condensing hot water heater although referred to as a boiler in this article, is a type of boiler that is much more efficient than the traditional type appliance. Extra efficiency is achieved by extracting more energy out of the flue gas as compared to that of a conventional boiler and using this energy to
Mar 19, 2016· The main difference between fire tube and water tube is that in fire tube boiler the flue gases flow in the tubes and water flows from the shell and in water tube boiler, water flows from the tubes and the flue gases from the shell or passes over the tubes. This is the key difference between these boilers.
Jun 05, 2018· Comparison Between Fire Tube and Water Tube Boiler. 1 In Fire-tube boilers hot flue gases pass through tubes and water surrounds them. In Water-tube boilers water passes through tubes and hot flue gasses surround them. 2 These are operated at low pressures up to 20 bar. The working pressure is high enough, up to 250 bar in super critical boilers.
Apr 23, 2016· Fire tube boiler. Water tube boiler. 1. In this boiler the hot flue gases is present inside the tubes and water surrounds them: The water is present inside the tubes and the hot flue gases surrounds them: 2. They are low pressure boilers. The operating pressure is about 25 bar. They are high pressure boilers and the operating pressure is about 165 bar. 3.
Typical designs are O, D and A type boilers Steam separation equipment - drum furniture Cyclone separators Demister pads Baffle plates Have economisers and superheaters Large water tube boilers are field erected and may be unique design Fire Tube Boilers
It adopt chain grate coal feeding design. Save Fuel Type DZL Coal Fired Hot Water Boiler Drawing Fire Tube Boiler | Operation and Types of Fire Tube Boiler Operation and Types of Fire Tube Boiler The water is fed into the boiler through the feed water inlet. There are mainly three types of external furnace fire tube boiler.

This boiler is a kind of fully automatic horizontal type fire tube oil gas fired hot water boiler with high thermal efficiency and it is safe and reliable.
Dec 20, 2018· Green Mechanic: Difference between Fire tube boiler and water tube Both are shell and tube type of boiler, fire tube have hot gases inside the tube while Steam pressure limit of the fire tube boiler is lies between 20-30 bar and the pressure Torsional Testing of
Fire tube boilers are used for supplying steam or warm water in small-scale applications.  Usually fire tube boilers consist of cylindrical chambers (1-3) where the main part of combustion takes place, and of fire tubes. In most of the cases, fire tubes are situated horizontally (fire tubes placed above chambers).
Two primary boiler types, the firetube boiler and the watertube boiler, are essentially opposite in design. The firetube boiler passes combustion gas inside a series of tubes surrounded by water in a vessel to produce steam, while a watertube instead sends water through a series of tubes surrounded by combustion gas used to transfer heat energy
May 05, 2017· A water tube boiler is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In Fire-tube boilers hot flue gases pass through tubes and water surrounds them.
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed 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..
Fin Tube Boilers. As in a water tube boiler, water passes through boiler tubes while combustion gases remain in the shell side, passing over the tube surfaces. Unlike conventional water tube boilers, however, the tubes in a fin tube boiler are fitted with fins, increasing the area available to transfer heat.
Flue gases flow through the flame tube and smoke tubes on the inside and boiler water flows around them on the outside. The flame tube, internal water-flushed rear flue gas reversing chamber, first smoke tube and second smoke tube are all arranged for optimum flow within the cylindrical pressure vessel.
FIRETUBE HOT WATER BOILER Thru-the-Door Design! Modified three-pass scotch marine fire tube boiler. Designed for minimal clearances where installation and floor space are the challenge. Durable features start with the thickest vessel shell in its class, along with large furnace volume for ultimate combustion efficiency.
Fire Tube type Hot Water Boiler for retailersZhengzhou Boiler Co.,Ltd (brand ZG) has a variety of efficient and reliable equipment platforms suited for retailers that require either hot water boiler or steam boiler. Retail owners and operators requiring. ZG is a steam boiler manufacturer in China.
Generally, the steam boiler with 0.5ton~2ton capacity is enough for a brewery, while, based on the production ability, the steam capacity is a little different. Sitong Boiler provides various models of fire tube 70t/h water tube boiler and hot water that necessary to the brewery. fire tube 70t/h water tube boiler in Paper Processing Industry
Aug 22, 2018· In fire tube boiler, the fuel is burnt inside a furnace. The hot gases produced in the furnace then passes through the fire tubes. The fire tubes are immersed in water inside the main vessel of the boiler. As the hot gases are passed through these tubes, the heat energy of the gasses is transferred to the water surrounds them.
