THE THEORETICAL DESIGN OF HOT-AIR HEATING ANTI-ICING SYSTEM AND APPLICATION IN ENGINEERING PRACTICE

Abstract

Abstract: Based on the principle of hot-air heating method, a anti-icing thermodynamics computational model is established for MW wind turbine blades. The model is used to calculate the time for melting ice attached on composite surface. The results show good agreements between the mathematical model and FEA. Then a hot-air heating anti-icing system designed by means of FEA, is equipped in a 2 MW wind turbine. The test in wind-farm shows that, in -10 ℃ environment, ice on the surface of blades starts to be melt in 45 minutes. This system could be applied to anti-icing of wind turbine blades.

Key words: wind-turbine blade, hot-air anti-icing, wind-farm test
