  当你使用热风炉时,经常会发现它很容易散热,而且有几种不同的散热现象。如果你想很好地解决这个问题,你需要弄清楚它有什么不同的热损失,这样你就能做点什么。
  When you use a hot blast stove, you often find that it is easy to heat, and there are several different heat dissipation phenomena. If you want to solve this problem well, you need to figure out what different heat losses it has, so you can do something about it.
  在日常应用热空气炉、热损失是一个很大的浪费的一部分,下面的双能小编您分析几个主要热损失的方法,在相关方面来解决,将极大地提高热空气炉的效率,节约资源,避免不必要的浪费。
  In the daily application of hot air furnace, heat loss is a big waste part, the following dual-energy small edition of your analysis of several main heat loss methods, in related aspects to solve, will greatly improve the efficiency of hot air furnace, save resources, avoid unnecessary waste.
  炉体热损失
  Heat loss of furnace body
  一般炉膛表面温度不应高于周围空气温度50℃。热风炉运行时,炉壁、钢架、管道等附件的表面温度高于周围温度,此时炉体表面散热。炉体表面积越大,保温性能越差,散热越大。
  In general, the surface temperature of furnace should not be higher than the ambient air temperature of 50 C. When the hot blast stove is running, the surface temperature of the furnace wall, steel frame, pipeline and other accessories is higher than the surrounding temperature. At this time, the surface of the furnace body dissipates heat. The larger the surface area of the furnace body, the worse the thermal insulation performance and the greater the heat dissipation.
  不完全燃烧造成的机械热损失
  Mechanical Heat Loss Caused by Incomplete Combustion
  热风炉机械不完全燃烧热损失是燃气锅炉热风炉的主要热损失之一。在燃烧固体燃料的燃气锅炉排放的灰和带有烟气的粉煤灰中,存在未完成的燃料颗粒和碳标定。这些未燃烧的固体中储存的热量称为热风炉中机械不完全燃烧产生的热量损失。液体和气体燃料机械不完全燃烧造成的热损失。

  Heat loss of mechanical incomplete combustion in hot blast stove is one of the main heat loss of hot blast stove in gas boiler. There are unfinished fuel particles and carbon calibration in ash discharged from gas-fired boilers burning solid fuels and fly ash with flue gas. The heat stored in these unburned solids is called heat loss caused by mechanical incomplete combustion in hot blast stoves. Heat loss caused by incomplete combustion of liquid and gas-fueled machinery.
  其他热损失
  Other heat losses
  固体燃料燃烧时,热风炉高温除渣所产生的热损失称为灰渣物理热损失。热风炉的其他热损失是指炉灰和炉渣带走的物理热损失的冷却热损失。热风炉的某些部分从一侧的烟中吸收热量,通过另一侧的水或空气进行冷却。水或空气带走的热量不能返回热风炉系统使用,造成热风炉冷却热损失。
  When solid fuel is burned, the heat loss caused by high temperature slag removal in hot blast stove is called the physical heat loss of ash. Other heat loss of hot blast stove refers to the cooling heat loss of physical heat loss taken away by ash and slag. Some parts of the stove absorb heat from the smoke on one side and cool through water or air on the other side. The heat carried by water or air can not be returned to the hot blast stove system, resulting in the heat loss of the hot blast stove cooling.
  三件物品的热损失与过量的空气量有关。当过量空气系数过大时,排烟的热损失增大,而化学不完全燃烧和机械不完全燃烧的热损失相应减小。反之,当过量空气系数减小时,排烟的热损失减小,而化学不完全燃烧和机械不完全燃烧的热损失增大。因此,使热风炉q2q3q4之和为小过剩空气系数,为佳过剩空气系数。
  The heat loss of three items is related to excessive air volume. When the excess air coefficient is too large, the heat loss of exhaust smoke increases, while the heat loss of chemical incomplete combustion and mechanical incomplete combustion decreases accordingly. On the contrary, when the excess air coefficient decreases, the heat loss of exhaust smoke decreases, while the heat loss of chemical incomplete combustion and mechanical incomplete combustion increases. Therefore, the sum of q2q3q4 in hot blast stove is the minimum excess air coefficient and the optimum excess air coefficient.
  以上内容是小编为大家整理的热风炉热损失情况分析,应该有很多人看完后知道是怎么回事。
  The above content is the analysis of heat loss of hot blast stove, which is arranged for you in a small part. Many people should know what is going on after reading it.
