近年来,我厂相继开发设计了SZL型6吨/时、8吨/时、10吨/时组装水管锅炉系列产品,6吨/时已于87年通过鉴定,8吨/时、10吨/时正在安装调试。由于这种类型的锅炉热效率高,结构紧凑,钢材耗量少,安全可靠,使用方便,安装容易周期短,锅炉房可以单层布置,基建投资节省,不仅适应各个工矿企业新增供汽、供热扩建改造的需要,而且适宜于老设备的更新,深受广大用户的欢迎。 相似文献

SZL型快组装水管锅炉系长短汽包纵向布置前置炉膛结构,目前国内已有20多家企业生产.而巨产量占整个工业锅炉产品的份额高达50%以上,由于其良好的快组装系列化性能,已经越来越为用户所熟悉和喜爱。随着中国高效工业锅炉项目的开展,这种护型在今后较长时间内势必成为中国工业锅炉的主导产品之一。现在提出该型锅炉开发试制初期在水循环方面曾有过的麻烦。就显得十分必要了。SZL10-1.25-AⅡ锅炉早期为江苏省联合设计而成;蒸汽锅炉及在此基础上开发的热水锅炉,在试制期及前期批量生产的该型锅炉产品中.绝大多数均发现炉膛后部或… 相似文献

A thermal model for the prediction of possible tube overheating was developed. The model incorporates a nonlinear state space dynamic model that captures the important physical interactions of the main variables of steam generation in naturally circulated water tube drum boilers. This paper provides an investigation of the dynamic effects of rapid rise in fuel flow rate (heat input) on the thermal and flow characteristics of the riser tubes in natural circulation water tube boilers. The system under consideration includes the drum, riser and downcomer as its major components. The dynamic response of the system's state variables due to rapid rises in fuel flow rates was investigated. The results show that the sudden rise in the firing rate is followed by an increase in the steam quality, which is accompanied by a decrease in the circulation rate as a result of increase in the pressure. The riser temperature increases slightly above the saturation temperature due to the increase in the steam temperature and due to the dynamic influence resulting from sudden increase in the heat flux. The present calculations of the water level in the drum provide good comparison with those in the literature. Copyright © 2009 John Wiley & Sons, Ltd. 相似文献

There has been considerable effort as to the manner in which the productivity of solar stills is affected by many of the designs and operating variables. To assist in designing the stills of improved performance, design parameters involved in the operation of the system have been considered in this paper. Curves showing the magnitude of the effects of design changes on the productivity are presented. Numerical computations, which are based on energy balances of different components of this system, confirm the productivity improvement in between 23.6% to 51.2% depending on the water-flow-rate from the vertical water column on the multiwicks. This design incorporates a multiwick solar still and a conventional basin type solar still. Hot water at considerably higher than the ambient temperature may be obtained at different flow rate from this design as well. 相似文献
