Recuperator or Heat Exchanger for Combustion Chamber

The invention comprises a recuperator shell mounted on a base. The shell has an internal hollow pipe for flue gas exhaust which is connected to an orifice at the base, orifice for air inlet and hot air outlet orifice . The internal hollow pipe is so designed that at its exterior cylindrical surface, multiple turns of a guide way are welded in a helical fashion. The angle at which each guideway is helixed is 45 degree which gives a tangential flow direction to natural fresh air entering through the orifice.
