2. FEATURES OF FIRE-TUBE BOILERS The fire-tube boilers are potentially dangerous as the steam pressures are high and volume of hot water and steam content is large. * water surrounds the tubes through which hot combustion gases pass before venting to atmosphere through gas uptakes. * water converted into high pressure steam by transfer of heat ...

Water-tube or fire-tube condensing boiler, which is the

These design changes have resulted in a marked improvement in heat transfer efficiency of the fire-tube boilers. Another outcome from this is that the overall footprint (boiler size) of the fire-tube boilers will be smaller in comparison to the water-tube boilers only in the lower capacities up to about 4,000,000 BTU/hr.

Heat Transfer Study in 3-Pass Fire-Tube Boiler During a Cold

In this work, we are interested to simulate the transient thermal-hydraulic behaviour of 3-pass fire-tube boiler during a cold start-up. A transient thermal model has been developed based upon energy balance equations of the main components of the boiler and the relevant correlations describing heat transfer phenomena taking place.

BOILER WATER TREATMENT

BOILER WATER TREATMENT INTRODUCTION A boiler is a closed vessel in which water under pressure is transformed into steam by the application of heat. In the boiler furnace, the chemical energy in the fuel is converted into heat, and it is the function of the boiler to transfer this heat to the contained water in the most efficient manner.

Boiler

In case of a locomotive-type boiler, a boiler barrel extends from the firebox and the hot gases pass through a bundle of fire tubes inside the barrel which greatly increases the heating surface compared to a single tube and further improves heat transfer. Fire-tube boilers usually have a comparatively low rate of steam production, but high ...
