The core consists of a series of radial plates between which are a series of triangular baffles arranged at an angle with the horizontal of 45 to 70 degrees. The baffles intercept the flow of flue gas and gently channel the flow of gas into a swirling pattern thereby enhancing convective heat transfer while maintaining low pressure …
