Design and Construction of a Portable Boiler

Abstract

The article describes a research which is focused on the design and construction of a portable boiler. This is to enhance energy system in Africa and the world at large. Water at atmospheric pressure of 1.613252bar, 25°c was supplied to the pressure to an absolute pressure of 4.5bar, a burner and liquefied petroleum gas (LPG) were used to supply heat to the boiler that raised the water at the copper piping to a saturation temperature or 147.9°c there by producing steam. During testing 0.5kg of gas was burnt for 25min and the wet steam generated at the exist pipe was at a gauge pressure of 3.2bar. The steam generated find application in textile industries for sizing and bleaching, sugar mills, chemical industries and production of hot water for hot water supply. In conclusion, the developed modular boiler is efficient and effective at optimal working condition.
