砼构件生产的能耗主要是用于蒸汽养护,而目前蒸养中蒸汽的利用率只有28％,其主要原因就是养护设施设计不合理,热损过大,当然也有管理方面的“跑、冒、滴、漏”等原因,因此,设计一种合理的养护窑或改造旧有窑体就显得非常重要了。几年来,我厂在养护设施上想了一些办法,即改造不合理的旧有养护设施,尽量采用先进的,特别是节能的工艺。现举几个实例如下: 一、折线窑折线窑是国内较为先进的窑型,主要特点就是节能,它利用起拱所造成的压差使窑内蒸汽不致外逸,热损极低,加之窑体保温良好,能节省大量能源。由于窑体呈弓背状,自然形成一个合理的养护温程:“升
The energy consumption for the production of thorium components is mainly used for steam curing, and the utilization rate of steam in the current steam curing is only 28%. The main reason is that the design of maintenance facilities is unreasonable, and the heat loss is too large. Of course, there are management aspects of running and taking. , Dripping, Leaking, etc. Therefore, it is very important to design a reasonable conservation kiln or rebuild an old kiln. Over the past few years, our factory has thought of some measures in the maintenance of facilities, namely the transformation of unreasonable old conservation facilities, and the use of advanced, especially energy-saving techniques. Here are a few examples as follows: First, the folding line kiln fold line kiln is a more advanced kiln type in China, the main feature is energy saving, it uses the pressure difference caused by the arch to make the kiln steam does not escape, heat loss is extremely low, plus the kiln The body is well insulated and can save a lot of energy. Because the kiln is arched, it naturally forms a reasonable conservation temperature:
