Water Tube Boiler: Construction, Operation - ME Mechanical

Jun 10, 2017· Special features of water tube boiler: Water tube boilers have the high evaporating capacity (20,000 to 40,000 kg/h) compared with other boilers. The operating pressure lies between 11.5 to 17.5 bar. The draft losses are minimum. The defective tubes in water tube boilers can be identified and replaced easily. The entire boiler rests on iron structures, independent of brick structure.

In a scotch boiler, the furnace is a large diameter tube, within the boiler, surrounded by water. Some older, large scotch boilers had two or three furnaces but modern boilers typically have only one. Scotch boilers may be two-pass, three-pass, or four-pass depending upon the arrangement of baffles and tubes.

Boiler Types and Classifications - Wiki - odesie by Tech

The most common fire-tube boilers used in facility heating applications are often referred to as ''scotch'' or ''scotch marine'' boilers, as this boiler type was commonly used for marine service because of its compact size (fire-box integral with boiler section). The name "fire-tube" is very descriptive.

Comparison Between Fire Tube and Water Tube Boiler

Jun 05, 2018· Comparison Between Fire Tube and Water Tube Boiler. 1 In Fire-tube boilers hot flue gases pass through tubes and water surrounds them. In Water-tube boilers water passes through tubes and hot flue gasses surround them. 2 These are operated at low pressures up to 20 bar. The working pressure is high enough, up to 250 bar in super critical boilers.

Boiler Efficiency: Introduction and Methods of Calculation

Combustion Efficiency. The combustion efficiency of a boiler is the indication of burners ability to burn fuel. The two parameters which determine the burner efficiency are unburnt fuel quantities in exhaust and excess oxygen levels in the exhaust. As the amount of excess air is increased, the quantity of unburnt fuel in the exhaust decreases.
