Subject syllabus
• Classification of heat exchangers. The importance of heat exchangers, energy saving, fuel savings, the degree of recuperation, increasing combustion temperature, increase performance aggregate.
• Thermal calculation of recuperator. The differential equation for the relationship between medium temperature and the size heat transfer surface. Solving equations for various cases boundary conditions.
• Dependence of temperature difference between the hot and cold streams on the size of the heat transfer surface. Calculation of the mean temperature difference.
• Overall heat transfer coefficient for the ceramic and metal recuperators. Influence of heat transfer coefficients on the overall heat transfer coefficient
• Heat rate of recuperator. Temperature heat transfer surfaces in the consideration or neglecting the thermal resistance of heat transfer surfaces, a criteria expression.
• The definition of heat exchanger effectiveness. Determination of heat exchanger effectiveness for the parallel-flow and counter-flow for different ratios between total heat capacities.
• Hydraulic calculation. Pressure loss by friction, local, geometric. Pressure losses resulting from non-isothermal flow mediums.
• Types of recuperators. Operating conditions.
