Natural gas is used as a heat source in the majority of modern drying plants in agriculture. The input gas is a mixture of natural gas and atmospheric air. With burning, the composition of this mixture changes. Drying medium is a mixture of hot combustion gases from natural gas and atmospheric air added. The thermic parameters of natural gas and atmospheric air are permanently constant. The authors present their method of the calculation of thermodynamic parameters of the drying medium. They elaborated two computer programmes in Q-Basic for the calculation related to the drying medium with temperatures in the range 100–200°C.Keywords:
