Abstract

The present investigations put forth the development of a novel double wall vented rotary fluid heating device. In this device, water is used as a process fluid and is heated by the combustion of sugarcane bagasse. The proposed combustion method is found to provide the use of a more systematic fuel transport system and ensure the efficient heat transfer process to the fluid. It is observed to offer many advantages over the conventional furnaces and obviates the use of any mechanized system such as traveling grate, fluidized bed system, dumping grate, etc. in conventional systems. Also, the heat liberated in combustion is used effectively for heating fluid through a helical coiled tube mounted over the surface of the drum. The present study aims to assess the thermal performance of the proposed rotary combustion chamber at different experimental parameters. It was concluded to have a maximum temperature rise, and the thermal efficiency of this system at 45.3C and 45.2% when drum speed is 6 RPM at Reynolds number equal to 1176.

螺旋盘管生物质燃烧旋转装置传热实验研究

本研究提出了一种新型的双壁通风旋转流体加热装置的研制。在该装置中，水被用作工艺流体，并通过甘蔗渣的燃烧而被加热。发现所提出的燃烧方法提供了更系统的燃料输送系统的使用，并确保了到流体的有效热传递过程。据观察，它提供了许多优于传统熔炉的优点，并避免了在传统系统中使用任何机械化系统，如移动炉排、流化床系统、倾卸炉排等。此外，燃烧中释放的热量通过安装在滚筒表面上的螺旋盘管有效地用于加热流体。本研究旨在评估所提出的旋转燃烧室在不同实验参数下的热性能。得出的结论是，当鼓转速为6RPM，雷诺数等于1176时，该系统具有最大温升，热效率分别为45.3C和45.2%。

期刊介绍： Journal of Thermal Enginering is aimed at giving a recognized platform to students, researchers, research scholars, teachers, authors and other professionals in the field of research in Thermal Engineering subjects, to publish their original and current research work to a wide, international audience. In order to achieve this goal, we will have applied for SCI-Expanded Index in 2021 after having an Impact Factor in 2020. The aim of the journal, published on behalf of Yildiz Technical University in Istanbul-Turkey, is to not only include actual, original and applied studies prepared on the sciences of heat transfer and thermodynamics, and contribute to the literature of engineering sciences on the national and international areas but also help the development of Mechanical Engineering. Engineers and academicians from disciplines of Power Plant Engineering, Energy Engineering, Building Services Engineering, HVAC Engineering, Solar Engineering, Wind Engineering, Nanoengineering, surface engineering, thin film technologies, and Computer Aided Engineering will be expected to benefit from this journal’s outputs.
