  介绍了间接热风炉的分类特点
  The classification characteristics of indirect hot blast stoves are introduced.
  主要用于不允许被污染的干燥物料,或用于温度较低的热敏性物料的干燥。如:奶粉、医药、合成树脂、精细化工等。这种加热装置,即以蒸汽、导热油、烟气为载体,通过各种形式的热交换器来加热空气。
  It is mainly used for drying materials which are not allowed to be polluted, or for drying heat sensitive materials with lower temperature. For example: milk powder, medicine, synthetic resin, fine chemical industry, etc. The heating device uses steam, heat conducting oil and flue gas as carriers to heat air through various forms of heat exchangers.
  间接热风炉的核心问题是热交换问题。换热面积越大,换热率越高,热风炉的节能效果越好,炉体和换热器的使用寿命越长。反之,热交换面积也可以从烟气温度来确定。烟气温度越低,热转化率越高,换热面积越大。
  The core problem of indirect hot stove is heat exchange. The larger the heat transfer area, the higher the heat transfer rate, the better the energy-saving effect of the hot blast stove, and the longer the service life of the furnace body and heat exchanger. Conversely, the heat exchange area can also be determined from the flue gas temperature. The lower the flue gas temperature, the higher the heat conversion rate and the larger the heat transfer area.
  燃料与热源分离后,可用于人体加热。
  After separation of fuel and heat source, it can be used for human heating.
  工作原理可分为蓄电池类型和换热式两种蓄电池类型,按下蓄电池的身体里面热高炉分球式热高炉炉(简称球)和热高炉使用网格砖,媒体可以分为顶燃式燃烧方式,内部燃烧类型,外部燃烧等几种类型。如何提高风温是业界长期研究的方向。常用的方法是混合燃烧高热值气体,或增加换热面积热高炉格子砖,或改变格子砖的材料,密度,或改变蓄热体的形状(如蓄热球),并通过各种方法将煤气和助燃空气预热。
  The working principle can be divided into two types: battery type and heat exchange battery type. According to the inside of the battery body, the hot blast furnace with ball-dividing type and grid brick used in the hot blast furnace, the media can be divided into top-burning combustion mode, internal combustion type and external combustion. How to improve the wind temperature is the direction of long-term research in the industry. The commonly used method is to mix combustion of high calorific value gas, or increase the heat exchange area to heat blast furnace lattice brick, or change the material, density of lattice brick, or change the shape of regenerator (such as regenerative ball), and preheat gas and combustion-supporting air through various methods.

  热的类型,主要是使用使用高温热交换器为核心部件,零件不能用金属陶瓷炉热交换器,只能用耐高温陶瓷换热器,在燃烧室气体充分燃烧,燃烧热空气,通过换热器,热的新鲜空气,可以让新鲜的空气温度高于1000度。
  The main type of heat is the use of high temperature heat exchanger as the core component, parts can not use ceramic furnace heat exchanger, can only use high temperature ceramic heat exchanger, in the combustion chamber gas full combustion, combustion of hot air, through the heat exchanger, hot fresh air, can make the temperature of fresh air higher than 1000 degrees.
  优点:传热温度高,热利用率高,体积小,热风温度稳定,无开关机构,使用寿命长,维护成本高,采购成本低。
  Advantages: high heat transfer temperature, high heat utilization rate, small volume, stable hot air temperature, no switch mechanism, long service life, high maintenance cost, low procurement cost.
  缺点:传热温度不如蓄热式高。
  Disadvantage: Heat transfer temperature is not as high as regenerative type.
