In this paper, a simple design method of gas immersed heat exchanger is put forward basing on the principle and formula of heat transfer. The key parameters in the design of gas immersed heat exchanger are studied, and the temperature drop of flue gas in a unit length tube of different diameters, shape, temperature of flue gas at the entrance and power is given. The deviation between the temperature at the exit calculated and that measured is less than 10%, which can meet the engineering requirement.
