Abstract:

The traditional method of the high-temperature elements of different thermal plants, connected with the use of heat-insulating materials, has substantial Shortcomings because a significant part of fuel energy is spent for cooling. A different, in principle, method is here connected with the technology of thermochemical recuperation adapted to the problem under consideration (thermochemical protection). The known model of such system has serious mistakes, and, hence, we have developed a more correct model, based on the calculation of fuel reforming and heat transfer of the reacting gas mixture with the wall. It is necessary to conform the intensities of these processes and, in such a way, to satisfy the conditions of energy balance. We present examples of calculations that open a possibility to do this.

Keywords: high-temperature elements, thermochemical protection, fuel reforming, heat transfer, energy balance, mathematical model.
