The advantages of a fire-tube boiler are its simple construction and less rigid water treatment requirements. The disadvantages are the excessive weight-per-pound of steam generated, excessive time required to raise steam pressure because of the relatively large volume of water, and inability to respond quickly to load changes, again, due to

Water Tube Boiler: * Water circulates in tubes and heated externally by hot gases. Fuel is burned inside the furnace. i.e (hot gases- outside the tubes and water- inside the tubes). * Operating pressure = upto 100 bar * Efficiency = upto 90% * Ste

Advantages & Disadvantages of Electric Heating | â">

Definition of BoilerAlthough electric heating offers considerable advantages, it also has certain disadvantages which gain significance depending on the climate in which you live. Reliability Some reliability related advantages include electric heating's solid safety record, and its lack of any dangerous point-of-use emissions or noise pollution, according to

Disadvantages: 1. There is a large diameter boiler shell, so the metal consumption is large. 2. Boiler capacity and pressure are limited. Generally, the capacity of a fire tube boiler doesn’t exceed 10 t/h and pressure doesn’t exceed 2 MPa. 3. The thermal efficiency is not as high as that of water tube boilers. Large water capacity and slow

Shell boilers may be defined as those boilers in which the heat transfer surfaces are all contained within a steel shell. Shell boilers may also be referred to as ‘fire tube’ or ‘smoke tube’ boilers because the products of combustion pass through the boiler tubes, which in turn transfer heat to the surrounding boiler …

Fire Tube Boiler Diagram. These boilers include a water level indicator; a pressure gauge, steam stop tap security tap, & a manhole like mountings for providing security as well as simplicity of working. The Fuel burns on the grate of the firebox in the boiler and the resultant hot-flue gases are permitted to flow in the region of cross tubes.

2012-7-30 · 2. Firetube boiler is so easy to use, operate, clean and maintain 3. Fire tube boiler can be used in small scale industries. 4. Fire tube boiler is relatively cheaper than water tube boiler. 2.3.2 Disadvantages of fire tube boiler: 1.From the furnace combustion side, required time to fill water is longer than to increase temperature and

Disadvantages are: liable to disastrous explosions because drums and joints are set over the fire, inaccessible for inspection, poor circulation, slow steamers, inefficient, pressure and capacity are limited. 4 types are; HRT, Locomotive, Scotch marine and vertical fire tube.

2004-3-19 · 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
