Different between Fire Tube Boiler and Water Tube Boiler
| | Fire Tube Boiler | Water Tube Boiler |
1. | The assembly is easy stiff with dense therefore the first cost is less. | Design is difficult thus early cost is elevated and it needs episodic examinations. |
2. | Every part are not simply accessible for cleaning, inspection or repair. | Every part is simply available for clean-up inspection or repair. |
3. | It has a little capability owing to smaller heating surface area resultant in slow speed of steam creation. It is not proper for steam power plants. | It has a extensive range of ability owing to lager heating surface area ensuing in high rate of steam creation. It is proper for big power plants. |
4. | It have a huge ratio of water contented to steam ability and thus slow in evaporation. | It have sensibly little percentage of water easy to steam with consequently rapid evaporation. |
5. | Flow is pitiable with thus there is each chance of a drop of impurities on the heated surface. Construction is such that taking away of impurities is not easy. | Spread is better so there are less probability of a putdown of impurities on the intense surface. Assembly is such that impurities if deposit from the water is found exterior zone of fast circulation and can be simply removed. |
6. | An explanation if it occurs turn into a extremely serious trouble in a fire tube boiler as of its large water capability. | As of small drum range the water is consistently extend in a large number of tubes, therefore the breakdown of one water tube does not reason any devastating explosion. |
7. | Breakdown in water supply is less effectual and might not burn the boiler due to large capability of water. | Breakdown in water supply system brings on a stop working as boiler might be excited owing to short capacity of water, |
8. | The Warm pipe gases flow within the tubes as water surroundings the tube. | The Water surge within tubes as the hot flue gases encircle the tube. |
9. | Stress consideration limits array of pressure as of 17.5 bar to 24.5 bar. Therefore it is proper for low Pressure. | It is able to endure high inside pressure for similar wall thickness with stress. Therefore, it is proper for pressures as elevated as 200 bar. |
10. | It is less efficient. | It is extremely efficient. |
