  fin material
The conductivity of the fin material has also been demonstrated to be an important factor to the thermal performance.
      
Numerical experiments are performed to study the influence of parameters namely the fin height, temperature of the heating source and the fin material on the average heat transfer coefficient.
      
The thermal properties of the fin material are assumed to be constant and the radiative exchange between the fin and its base is neglected.
      
The optimum arrangement is dependent on fin thermal conductivity, tube diameter, volume of fin material per unit length of tube, and temperature difference between the tube and the surrounding air.

The traditional approach to the optimization of the heat transfer of fins consists of minimizing the comsumption (investment) of fin material for the execution of a specified heat transfer task. The minimum weight cooling fin has optional profile to be a concave parabola. Therefore, the optimum geometric dimensions of circular fins of parabolic profile with variable thermal parameters are studied.

The traditional approach to the optimization of the heat transfer of fins consists of minimizing the comsumption (investment) of fin material for the execution of a specified heat transfer task. The minimum weight cooling fin has optional profile to be a concave parabola. Therefore, the optimum geometric dimensions of circular fins of parabolic profile with variable thermal parameters are studied. The effect of the two pertinent physical parameters - thermal conductivity variation parameter a and the index of the heat transfer coefficient variation m upon the optimum geometric dimension has also been studied. An invariant imbedding technique has been used in this study. The results presented can be used as the design guideline for engineering practice.

According to the task of Sixth Five-Year Plan, the fin materials for 130 t/h fluidized-bed for firing coal gangue have been investigated based on the characteristics of fluidized-bed combustion (FBC) systems. It is indicates that the fin materials have adequate high temperature strength and hardness, good oxidation and corrosion resistance by adding certain amount of Cr, Mo, V, Si alloying elements. The new materials have been in service for 4300h in FBC. The results of pilot-plant showed that the erosion value has only about 0-4mm. According to the extrapolated value of erosion rate, the lifetime of the new fin materials will come up to 20000h, which is about 3 times greater than the lifetime of 16Mn steel, the orginal fin material.
