如果采暖系统中存在大量的空气,热力设备和采暖系统的管道及附除就会受到腐蚀,同时也影响热水采暖系统的循环至致使散热器不能正常散热。及时及将系统内的空气排掉,会延长系统的使用寿命,并且可以减少燃料的消耗量,提高系统运行的经济性。 相似文献

为回收一台52m^2铁矿烧结机的冷却过程余热资源,回用于烧结原料的混合和加热过程,实际设计—套基于热管元件的余热锅炉系统。该系统以热管为主要传热元件,以分离式汽化套管为蒸汽发生器,以直立式翅片结构为强化传热手段,使之适应烧结冷却废气的流量、温度和含尘量特点。经过至今约8年的实际运行,该系统几乎可以稳定地提供6t/h的饱和蒸汽,并且对于铁矿烧结过程具有较好的适用性和经济效益。 相似文献

"Ondol" is a Korean unique heating system. It is a specific radiant floor heating system using combustion heat of briquette or timber in Korea. Such traditional "Ondol" is changed to radiant heating system with pipe-coil embedded in the floor or slab. This study has contributed to the understandings of the transient behaviours of Ondol-heated floor panels and enclosure exposed to this type of heating system. The result is that the water supply temperature had a large effect on the rate of increase in floor surface and room air temperature. But, in spite of a higher water supply temperature, the heat flow rate was not increased considerably. The shallow pipe embedding depths, of course, result in a low heat flow rate. 相似文献

Application of the porous medium combustion technology in the chamber reheating furnaces at Baosteel
《Baosteel Technical Research》2012,6(2):60-63
The design of the porous medium combustion ( PMC) system which has been applied to chamber reheating furnaces is presented in this study and its main application effects are described in detail. Porous medium materials are mainly ceramic ball sucked granular bed porous media and foam ceramic porous media. This study investigates the foam ceramic porous medium and a schematic diagram of the combustion inside this porous medium. The PMC takes a solid medium as its main heat exchange way,thus greatly improving the heat transfer efficiency. Judging from the application effects,the following conclusions have been made: the PMC technology can save more than 25% of energy with remarkable effects; the furnace temperature uniformity can be significantly enhanced; the porous media combustion technology can make the heating furnace design in a more compact way,reduce the time for heating up the furnace, improve the heating rate and reduce energy consumption. 相似文献
