Abstract


In most boilers, solid fuels are used, which are prone to issues of partial combustion. This occurs due to various reasons such as inadequate oxygen, improper air delivery system, etc. In this work, an attempt has been made to avoid/overcome the issue of partial combustion by increasing the pressure at the end of the air delivery system without increasing the inlet pressure. Moreover, effectively increasing velocity after air exit and turbulence aids in the complete combustion of the solid fuel. Efficiency is expected to increase by up to 10-15% due to complete combustion.
