                客户选用燃煤热风炉需要知道的几个原则

                燃煤热风炉的选用方法虽然不是很复杂,但是大家在选择的时候如果不想出现意外的话,可以先看一看在选择的过程〓之中需要注意的原则有哪些了。下面的这些内容ξ 就是当我们在选择燃煤热风炉的时候一定要遵守的几个原则。每种燃煤热风炉都有其特定的适用范围,而每种物料都可找到若干种能满足基本要求的燃煤热风炉,但最适合的只能有一种。如选型不当,用户除了要承担不必要的一次性高昂采购成本外,还要在整个使♀用期内付出沉重的代价,诸如效率低、耗能高、运行成本高、产品质量差、甚至装置根本不能正常运行等等。燃煤热风炉小编带大家了解关于〖燃煤热风炉选型的九项原则。
                Although the selection method of coal-fired hot blast stove is not very complicated, if you don't want to have any accidents in the selection process, you can first look at the principles that need attention in the selection process. The following are some principles that we must abide by when choosing a coal-fired hot blast stove. Each kind of coal-fired hot-blast stove has its specific application scope, and each material can find several kinds of coal-fired hot-blast stoves which can meet the basic requirements, but the most suitable one can only be found. For example, improper selection, users should not only bear the unnecessary one-time high procurement costs, but also pay a heavy price in the whole service life, such as low efficiency, high energy consumption, high operating costs, poor product quality, and even the normal operation of the device and so on. We all know about the nine principles of selection of coal-fired hot blast stoves. 1.选型前最好能做出物料的干燥实验,深入了解类似物料已经使用的燃煤热风炉(优缺点),往往对恰当选型有帮助。
                1. It's better to do drying experiments of materials before type selection. It's often helpful to know the advantages and disadvantages of coal-fired hot blast stoves that have been used for similar materials.

                2.不完全依赖过去的经验,注重吸收新技术,多听专家的意见。
                2. Not totally dependent on past experience, pay attention to absorbing new technologies and listen to experts'opinions.

                3.耗能低-------不同干燥方法耗能指标不同,一般传导式干燥的热效率理论上可达100%,对流▂式干燥只能70%左右。
                3. Low energy consumption - - - different drying methods have different energy consumption indicators. The thermal efficiency of conductive drying can reach 100% theoretically, and convective drying can only reach about 70%.

                4.节省投资-----完成同样功能的燃煤热风炉,有时其造价相差悬∩殊,应择其低者选用。
                4. Save investment - --- Coal-fired hot blast stoves with the same functions are sometimes very different in cost, so the lower one should be chosen.

                5.运行成本低---设备折旧、耗能、人工费、维修费,备件费…等运行费用要尽量低廉。
                5. Low operating costs - depreciation of equipment, energy consumption, labor costs, maintenance costs, spare parts costs. The operation cost should be as low as possible.

                6.干燥速率高---仅就干燥速率看,对流干燥时物料高度分散在热空气中,临界含水率低,干燥速度快,而且同是对流干燥,干燥方法不同临界含水率也不同,因而干燥速率也不同。
                6. High drying rate - In terms of drying rate, materials are highly dispersed in hot air during convective drying. The critical moisture content is low and the drying speed is fast, and the same convective drying method has different critical moisture content, so the drying rate is different.

                7.优先选择结构简单、备品备件╳供应充足、可靠性高、寿命长的燃煤热风炉。
                7. Priority should be given to coal-fired hot stoves with simple structure, adequate spare parts supply, high reliability and long service life.

                8.适用性-------燃煤热风炉首先必须能适用于特定物料,且满足物料干♀燥的基本使用要求,包括能很好的处理物料(给进、输送、流态化、分散、传热、排出等),并能满『足处理量、脱水量、产品质量等方面的基本要求。 9.符合环保要求,工作条件好,安全性高。
                8. Applicability - - - Coal-fired hot blast stove must first be suitable for specific materials, and meet the basic requirements of material drying, including good handling of materials (feed, transport, fluidization, dispersion, heat transfer, discharge, etc.), and can meet the basic requirements of processing capacity, dehydration capacity, product quality and so on. 9. It meets the requirements of environmental protection, has good working conditions and high safety.
