(b) Cochran (vertical shell) horizontal tube. Various advantages of fire tube boilers are as follows. (i) Low cost (ii) Fluctuations of steam demand can be met easily (iii) It is compact in size. 2.1.2 Fire-Tube Boiler This boiler consists of a cylindrical shell with its crown having a spherical shape. The furnace is also hemispherical in shape.
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
Factory owners must ensure the boiler is
The owner of a boiler can be prosecuted and fined a maximum of $50,000 for operating the boiler:─ * without statutory examination or a valid certificate of fitness. * without direct supervision of a competent person. 2. FEATURES OF FIRE-TUBE BOILERS The fire-tube boilers are potentially dangerous as the steam pressures are high

May 31, 2015 · engineer. Proper boiler venting is critical for operation of your boiler. The flue must be as large or larger than the diameter of the collar opening. Actual sized depends on total distance of flue. It is important to keep the vent pressure at a negative and it is even more important that the pressure is no more negative than -0.05” wc.
