The water is surrounded by heated gases rather than the other way around in the water tube configuration. The hot gas travels from the firebox to t
suijitupian60.jpg" />The furnace can be situated at one end of a fire-tube which lengthens the path of the hot gases, thus augmenting the heating surface which can be further increased by making the gases reverse direction through a second parallel tube or a bundle of multiple tubes (two-pass or return flue boiler); alternatively the gases may be taken along the
suijitupian98.jpg" />The steam piping (with steam flowing through it) is directed through the flue gas path in the boiler furnace. This area typically is between 1,300 °C (2,372 °F )-1,600 °C (2,912 °F). Some superheaters are radiant type (absorb heat by radiation), others are convection type (absorb heat via a fluid i.e. gas) and some are a combination of the two.

suijitupian64.jpg" />Fire-tube boiler. In this boiler, the products of combustion/hot flue gases flows inside and the water flow outside of the boiler tubes. Figure 27.1shows the fire-tube boiler. The examples of the fire-tube boilers are (a) Cochran, (b) Lancashire, (c) Cornish and (d) Locomotive boilers. Fig. 27.1. Fire-tube Boiler. Water-tube boiler. In water
suijitupian138.jpg" />Answer (1 of 3): Can you plz elaborate the question. You just want to either see the Water tube boiler image or it's working. There are basic two types of Boiler 1. Fire tube Boiler 2. Water tube Boiler Fire tube boiler- In this Boiler Flue gases flow inside the Tube and water flow outside the
suijitupian33.jpg" />See Page 1. Differences between Water Tube and Fire Tube Boilers: Department of Mechanical & Manufacturing Engineering, MIT, Manipal 8. Steam Boilers Question Bank Sl. No. Questions 1 Sate the difference between forced circulation and natural circulation boiler. 2 Among the two, fire tube and water tube boilers which one can generate steam faster?
suijitupian198.jpg" />Fire Tube Boilers:A fire tube boilers, is the boiler wherein the products of combustion pass through inside of the tubes (either one or several) and water which is to be converted in to steam is made to surround outside these tubes. Start up and bringing to full load is faster compared to fire tube boilers, d) Fairly long path of flue gas
suijitupian63.jpg" />Direct the path of the gases of combustion so that the maximum heat will be absorbed by the water before the gases of combustion enter the breeching and chimney. A flue gas analyzer that measures the percentage of carbon dioxide, oxygen & carbon monoxide in the gases of combustion Found on fire tube boilers (HRT & scotch marine) to keep
suijitupian64.jpg" />Sep 05, 2020 · Lancashire boiler works on the principle of the heat exchanger.The heat is a transfer from exhaust gases to the water through convection. It is a natural circulation boiler which uses natural current to flow the water inside the boiler.. It is basically a shell and tube type heat exchanger in which the exhaust gases flow through the tubes and the water flows through shell.
suijitupian81.jpg" />It is a stationary fire tube, internally fixed, horizontal natural circulation boiler as shown in Fig. 3. This is a widely used boiler because of its good steaming quality and its ability to work coal of inferior quality. These boilers have a cylindrical shell 2m in diameter and its length varies from 8m to 10m.
suijitupian72.jpg" />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 …
suijitupian158.jpg" />Mar 01, 2019 · In general, the furnace of fire-tube boilers was widely studied,, . A numerical study on the integration of the gas burner into the furnace space of the hot-water boiler was carried out in . The results of calculating the distributions of the velocity of flue gases, temperature fields and concentrations of nitrogen oxides showed the necessity
suijitupian14.jpg" />Based upon relative position of water and flue gas (hot gas) carrying tubes, 1) Fire tube boiler 2)Water tube boiler Based upon location of furnace, 1) Externally fired boiler 2) Internally fired boiler Based upon method of water circulation, 1) Natural circulation 2)Forced circulation Based upon …
