The studies were carried out at the Agricultural Engineering Department laboratory of ASU. The studies included the use of fully closed and semi-open steam diffuser protecting shields. The research focused on shifting the lengths of protecting shields: 20, 25, 30, 35, 40, 45 and 50 cm. The studies were performed at varying wind speed side-on - 1, 2, 3, 4 and 5 m/s. When the shields are only side-on and when the steam diffuser is fully closed, the maximum temperature in the plant is influenced differently by the wind speed. When the protection shields are side-on and the length varies from 20 – 50 cm, the temperature in the central part of the plant reaches 29.1 to 66.9 °C, whereas, in case the plant is affected by a fully closed steam diffuser the temperature in the central part of the plant model reaches from 49.6 to 84.6 oC. The optimal length of the closed steam diffuser protecting shields is from 25 to 30 cm. In conclusion, the research data indicates that when the steam diffuser is fully closed the achieved temperature is higher in comparison when the steam protecting shields are placed side-on.
