In addition to operating portable boilers, such as the Scotch marine and vertical fire-tube boilers. the Utilitiesman must also be able to operate stationary boilers, both in the plant and in the field. A STATIONARY BOILER can be defined as one having a permanent foundation and not easily moved or relocated.

THE HORIZONTAL-RETURN TUBULAR BOILER

Jun 17, 2015· In the horizontal-return tubular (HRT) fire-tube boiler the boiler shell is a horizontal cylinder closed at each end by a flat tube sheet or head. The fire tubes, which are usually 3 to 4 in. … In the horizontal-return tubular (HRT) fire-tube boiler the boiler shell is a horizontal cylinder closed at each end by a flat tube sheet or head. The fire tubes, which are usually 3 to 4 in. in diameter, extend through the boiler from one tube sheet to the other and are rolled or expanded into the tube sheets at each end, thus serving not only

Water Tube Boiler | Operation and Types of Water Tube

Mar 04, 2020· Larger heating surface can be achieved by using more numbers of water tubes. Due to convectional flow, movement of water is much faster than that of fire tube boiler, hence … Larger heating surface can be achieved by using more numbers of water tubes. Due to convectional flow, movement of water is much faster than that of fire tube boiler, hence rate of heat transfer is high which results into higher efficiency. Very high pressure in order of 140 kg/cm 2 can be obtained smoothly.Advantages of Water Tube Boiler1. Larger heating surface can be achieved by using more numbers of water tubes. 2. Due to convectional flow, movement of water is much faster thanWorking Principle of Water Tube BoilerMore and more steam is produced the pressure of the closed system increases which obstructs this convectional flow of water and hence rate productiTypes of Water Tube Boiler1.

Boiler Preparation, Start-Up and Shutdown

10 To start the warm up, open the drain on the non-return valve. It is important to know that this drain is actually connected internally to the downstream side of the valve plug. Next, open the header valve … 10 To start the warm up, open the drain on the non-return valve. It is important to know that this drain is actually connected internally to the downstream side of the valve plug. Next, open the header valve a slight amount, allowing steam to flow from the steam header into the boiler steam line and out the drain.
