examination of fire tube boiler internally and externally

A fire-tube boiler is a type of boiler in which hot gases from a fire pass through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction , heating the water and ultimately creating steam . The fire-tube boiler developed as the third of the four major historical types of boilers: low

LOCOMOTIVE BOILER Locomotive boiler is a horizontal fire tube type mobile boiler. The main requirement of this boiler is that it should produce steam at a very high rate. Therefore, this boiler requires a large amount of heating surface and large grate area to burn coal at a rapid rate.

Boiler tubes can be internally inspected by a fiberscope type of instrument that can give a TV picture of the inside of the tubes. Sometimes sections or tubes may be cut out for inspection and replacement. Internal boiler scale (deposits) may indicate the need for chemical cleaning. The tube in Figure 3 is in definite need of chemical cleaning.

14-9.1 Tube ends of fire tube boilers 14-9.2 Tube ends of water tube boilers and superheaters under pressure or vacuum for use externally to itself by the application of heat from combustible fuels, electricity, or Portable boiler means an internally fired boiler primarily intended for temporary location and whose construction

Boilers examined internally and externally and found to be or placed in a satisfactory condition. Class II All Fire-tube Boilers (including automatically controlled) and Steam Receivers BOILERS AND PRESSURE VESSELS (FORMS) ORDER SCHEDULES-24 Cap. 56B.

Fire Tube Boilers Fire Tube boilers in common use are— A. Vertical Tubular Boilers. There are various designs and makes of this type of boiler but the following are commonly en-countered. (i) Vertical Cross Tube Boiler—In its simplest from the boiler (Fig. 1) consists of a cylindrical shell surrounding a nearly cylindrical fire-box.

High Risk Boilers: All boilers other than Small Industrial Boilers, Vertical cross tube Boilers and Lancashire Boilers. Procedure for Thorough Examination as per Reg 390 of IBR,1950: a) For examination of boiler, the boiler shall be empty and thoroughly clean in all its parts i.e., shell, tubes and furnace chambers internally as well as externally.

Describe the physical properties, use and action of suitable chemicals for treatment of the water and protection of the associated piping of a water-tube boiler operating at 54 kg/cm2 9600F. Describe the complete examination both internally and externally of either: (a) a …
