摘要沥青船的货舱加热系统作为其最主要的组成部分，在整个运输过程中为沥青提供加热，保温所需的热量，保证整个过程中沥青处于液态，使得沥青可以通过管道输送，让运输过程变得方便快捷。以前沥青用的都是国外租下来的，国内的沥青船制造技术不够完美。这篇论文为研究37000吨沥青船液货加热系统。86825

    本文以37000DWT沥青船为例，开头介绍了沥青船的研究背景以及国内外研究对象，另外介绍了沥青的特点。然后通过比较热油系统的优缺点，在设计热油加热系统之前先对燃油热油加热系统原理进行设计，本文对沥青船的货舱加热系统进行设计，采用数值计算的方法对货舱加热，保温所需的热量进行计算，确定加热设备的选择之后，根据设计规定和理论进行选型。同时对燃油热油锅炉、、热油循环泵、导热油油柜的计算与选型。此外对沥青船加热管系进行计算设计。

Abstract The heating system of the asphalt tanker is the most important part of the system。In the whole process of transportation to provide heating for the asphalt, the heat required to heat, to ensure that the entire process of asphalt in the liquid, so that asphalt can be transported through the pipeline, so that the transport process becomes convenient and quick 。Before asphalt domestic carriers by foreign imports or rented boat asphalt, and so far the country's manufacturing asphalt tanker technology is not mature。 In this context the domestic situation, I would be in 37000DWT liquid cargo ship bitumen heating system design。

In this paper, 37000DWT asphalt boat, for example, at the beginning introduces the research background and the object of study abroad asphalt boat, another describes the characteristics of asphalt。 Then compare the advantages and disadvantages of hot oil through the system, the design of the thermal oil heating system before the first of the hot oil hot oil heating system design principles, followed by the design requirements for thermal analysis and calculation of fuel oil boiler, be selected according to the design requirements and theoretical type。 Meanwhile heat the fuel oil boiler, gas fired boiler, hot oil circulating pumps, oil fuel tanks of calculation and selection。 In addition to the asphalt heating pipe system to calculate the ship design。

Keywords:Asphalt Ship;System Design and Selection;Heating pipe system。
