According to flow of water and hot gases: 1. Water tube. 2. Fire tube. In water tube boilers, water circulates through the tubes and hot products of combustion flow over these tubes. In fire tube boiler the hot products of combustion pass through the tubes, which are surrounded, by water. Fire tube boilers have low initial cost, and are more

gas and water in a fire-tube boiler is considered. In the literature, a comprehensive modeling for fire-tube boilers has not been treated. Generally, the few models found are focused to one aspect of the fire-tube boiler performance as the gas/fire side or the water/steam side, and normally centered on nominal operating conditions.

Aug 27, 2015 · Boiler Uptake Fire and Exhaust Gas Economiser Fire. Auxiliary boiler uptake or flue gases normally pass through economisers or air pre-heaters or feed water heaters. All these types of heat exchangers are fin type. Hence large amount of carbon or soot deposits on the fins. Along with the flue gases some un-burnt carbon particles also get
Aug 30, 2019 · Fire Tube Boiler. In Fire Tube Boilers, hot flue gases will be flown inside the tube and these tubes are surrounded by water. These are the low-pressure boiler which cannot generate much heat compared to water tube boilers. As the production of heat is less the overall efficiency of this boiler is also low. The figure which depicts the fire tube boiler is shown below.

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) In the locomotive-type boiler, fuel is burnt in a firebox to produce hot combustion The furnace remains a single large-diameter tube with the many small tubes The immersion fired boiler is a single-pass fire-tube boiler …
Introduction. Fire tube boilers, also known as smoke tube boilers, are the most common type of industrial boiler employed today. Compared to water tube boilers, they are much more suitable for smaller plant applications because they can better cope with sudden high demand steam fluctuations.. Combustion occurs within a furnace with the exhaust gasses (flue-gasses) passing through a series of
Feb 12, 2019 · Locomotive boiler is a fire tube type boiler. Multi tube is involved in it; all the tubes are horizontally in the horizontally placed drum. It has 116 general fire tube and around 38 super heated fire tube. Furnace that produces heat over the burning of coal is located inside the boiler and hence it is an internally fired boiler.
The Fire tube boiler is intended for transmitting hot-gases using heat source as well as cycle. These gases flow through pipes with a water-filled drum. This procedure efficiently transmits the heat from the hot gas to the water, which efficiently produces steam.
According to flow of water and hot gases: 1. Water tube. 2. Fire tube. In water tube boilers, water circulates through the tubes and hot products of combustion flow over these tubes. In fire tube boiler the hot products of combustion pass through the tubes, which are surrounded, by water. Fire tube boilers have low initial cost, and are more
Fire Tube - an overview | ScienceDirect Topics
Fire tube boilers represent one of a number of pressurized equipment options used to heat water or convert water into steam under controlled conditions. In fire tube boilers, combustion gases pass inside boiler tubes, and heat is transferred to water on the shell side. Fire tube boilers are most commonly used where required steam pressures do
i) The most common flue gas measurement location is immediately downstream of the steam generation section of a water-tube type boiler. For a fire-tube type boiler the flue gas sample is most commonly taken as the exhaust gases exit the boiler proper. i) Establish tune-up timeframe.
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
boiler output can be difficult for a boiler originally designed to burn coal. Higher tube -metal temperatures may be experienced when firing natural gas. In some cases, a unit derate of 15% or more, may be necessary to reduce flue gas and tube-metal (superheater, reheater) temperatures in the
Firebox—the area of a boiler where the burners are located and where radiant heat transfer occurs, p. 296. Fire tube boiler—a device that passes hot combustion gases through the tubes to heat water on the shell side, p. 298. Igniter—a device (similar to a spark plug) that automatically ignites the flammable
A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or more tubes running through a sealed container of water. The heat of the Fire Tube Boiler - Construction, Types and Its Working - ElProCus
