MUMBAI, India, Nov. 28 -- Intellectual Property India has published a patent application (202411025951 A) filed by Engineers India Limited, New Delhi, on March 29, 2024, for 'a fired heater.'
Inventor(s) include Mandip Kapoor; Rajesh Patel; Shilpa Singh; Rajesh Singh; Rupam Mukherjee; and Marcus Barla.
The application for the patent was published on Nov. 28, under issue no. 48/2025.
According to the abstract released by the Intellectual Property India: "Present disclosure relates to an innovative tube configuration in the firebox which does not use any 180 degree return bend and allows the placing of a higher number of tubes on all four walls (W) of the cabin heater firebox. In this arrangement, tubes (20) are 5 connected through 90 deg. bends and can be placed closely on all 4 walls (W) of the firebox, while being supported through vertical pipe-column supports or conventional wall tube hangers. The tubes (20) on at least one of the walls of the firebox need to be at a gentle slope and can be kept horizontal at other walls. This configuration has multiple advantages with respect to the existing fired heater tube arrangements, like 10 placement of tubes irrespective of standard tube pitch as no 180deg. standard return bend is used, maximization of heat transfer area within a defined fire box volume, uniform heat flux & hydraulic symmetry in all passes (including odd passes)."
