Combustion Chamber of Boiler to Generate Tornado Effect

Abstract

Introducing modern boiler concepts in the design of thermal power stations is nowadays becoming mandatory, not only from an economic point of view of new investments, but also as a significant and pro-active step towards the reduction of greenhouse gases & dust emissions by the enhancement of efficiency.The current work introduces a model design of combustion chamber of boiler which works on the principle of tornado effect most of which is formed from a thunderstorm. Tornado is violent, rotating column of air extending from a thunderstorm to the ground. For creating tornado, warm moist air and cool dry air is required. When these two air masses meet, they create instability in the environment. A change in wind direction and increase in wind speed and increasing height creates a horizontal spinning effect in the lower atmosphere. In the similar way, a flame is created in the combustion chamber. The flame is rotated with the help of primary motor and as the air is given to the chamber mixing of hot air and cold air occurs and due to the rotation, the flame moves upwards like a tornado. The main objective of the paper is to propose a design a novel combustion chamber of a boiler utilizing tornado-like vortex flow.
