Construction of a vertical fire tube boiler

Thesis Overview

<p> </p><p>INTRODUCTION</p><p>The term “boiler” applies to a device for generating: Steam for power, processing or heating purposes; Hot water for heating purposes or hot water supply. Boilers are designed to transmit heat from an external combustion source (usually full combustion) to a fluid contained within the boiler itself.</p><p>Boilers can be broadly grouped into lower pressure type and high pressure boiler. The constructed vertical fire tube boiler is a low pressure boiler. The boiler is constructed so as to generate steam for chemical engineering processes, heating drying, sterilizing, etc.</p><p>Holes at triangular pitch were drilled at the bottom and top sheet plates of the boiler. Steam tubes were passed through these holes and then welded strongly. Other holes were drilled only on the top plate, so that steam will pass through them. This was pushed in to a shell and welded together. A mild steel plate was used to prevent the products of combustion passing from the steam tubes to come into contact with the generated steam. A stack was provided for the flue gases to escape.</p> <br><p></p>
