چکیده

در پژوهش حاضر به مطالعه تجربی تولید بخار خورشیدی با استفاده از چوب درخت کاج پرداخته می‌شود. ویژگی‌های منحصر به فرد چوب نظیر تخلخل بالا، آب دوستی، سبکی و ضریب هدایت حرارتی پایین باعث شده است تا جهت محلی‌سازی نور در سطح آب و تولید بخار خورشیدی در این پژوهش مورد توجه قرار گیرد. برای این منظور در گام نخست به مقایسه بخار تولیدی آب و چوب درخت کاج که قادر است در سطح آب شناور باشد، پرداخته می‌شود. نتایج نشان می‌دهد استفاده از چوب معمولی به عنوان غشاء سطحی باعث بهبود فرایند تبخیر می‌شود به طوری که نرخ تبخیر آن 3/26 درصد در مقایسه با نرخ تبخیر آب افزایش می‌یابد. به منظور افزایش جذب نور و نرخ تبخیر، سطح چوب توسط یک صفحه‌ی داغ فلزی با دمای 400 درجه سانتی‌گراد کربنیزه می‌شود. علاوه بر این ضخامت بهینه چوب و نیز اثر مدت زمان فرایند کربنیزاسیون در نرخ تبخیر مورد مطالعه قرار می‌گیرد. نتایج تبخیری نشان می‌دهد که ضخامت بهینه چوب 10 میلیمتر و زمان کربنیزه 150 ثانیه می‌باشد. به طوری که استفاده از چوب کربنیزه با این ویژگی نرخ تبخیر را نسبت به آب تا 86/1 برابر افزایش و بازده تبخیری 2/64 درصد را به خود اختصاص می‌دهد.

چکیده [English]

In the present paper, an experimental study using pinewood in a solar steam generation is carried out. The unique properties of wood such as high porosity, hydrophilicity, lightness, and low thermal conductivity have led to consider for localizing light on the water surface and generating steam in this paper. At the first step, steam generated by water and the pinewood which can float on the water surface was compared. The results showed that the wood as a surface membrane can improve the evaporated mass so that its evaporation rate increased to 26.3% of water. To enhance the light absorption via wood and evaporation rate, wood’s surface was carbonized with a metal plate at a temperature 400°C. In addition, the optimum thickness and the effect of the duration of the carbonization process were tested. According to the results, the optimum thickness of carbonized wood and carbonized time were 10 mm and 150 s respectively. However, using carbonated wood enhanced the evaporation rate about 1.86 times larger than water and allocated evaporation efficiency of 64.2 % to itself.
