摘要： 锅炉作为一种能源转换设备,在工业生产中得到了广泛的应用。它通过煤、石油或天然气的燃烧放出的化学能，并通过传热把热量传递给水，使水加热（或变成蒸汽），热水直供给工业生产和民用生活、供暖，所以锅炉的主要任务是：把燃料中的化学能最有效的转变为热能。本次毕业设计的题目是SHL10-2.5/400-A。在整个设计过程中，作为技术支持进行了热力计算、强度计算和烟风阻力计算。为了是小型锅炉的结构紧凑，大部分受热面都布置在炉膛内，同时，还要确保有一定的气密性来保证炉膛内进行负压燃烧。同时，利用CAD绘制出锅炉总图，本体图，集箱图，炉墙图。24758

Thermal design of SHL10-2.5/400-A boiler
Abstract: Boiler is one kind of energy conversion equipment, has been widely used in industrial production. Combustion chemistry by coal, oil or natural gas, and heat the heat transfer through the water, the water heating (or vapor), direct hot water supply to the industrial production and civil life, heating, so the main task of boiler is: convert the chemical energy of the fuel into heat energy the most effective.
The graduation design topic is SHL10-2.5/400-A.
In the whole process of design, as a technical support for the calculation of the thermodynamic calculation, strength calculation and smoke wind resistance. In order to small boiler has the advantages of compact structure, large heating surface are arranged in the furnace, at the same time, to make sure that there are certain to ensure airtight negative pressure within the combustion chamber.
At the same time, using CAD to draw the boiler body general layout, map, set box, furnace wall chart.
