一、问题的提出我国马尾松松脂加工蒸馏具有较高的终点蒸馏温度,为了满足生产工艺要求,蒸汽法炼香一般都采用高温过热蒸汽为热源。对于大、中型锅炉来说,过热蒸汽的产生是较为方便的,并由锅炉厂配套设计具有附属的炉内蒸汽过热器,但因蒸发量太大,对我国大多数蒸汽炼香工厂并不适用。中、小型蒸汽炼香工厂日产松香15—60吨,通常只需1—4吨蒸汽/小时,因此普遍选用运输安装方便,结构紧凑的快装锅炉生产蒸汽。然而
First, the issue put forward China’s masson pine resin processing distillation has a higher end point distillation temperature, in order to meet the requirements of the production process, the steam method Lianxiang generally use high temperature superheated steam as a heat source. For large and medium-sized boilers, superheated steam generation is more convenient, and the boiler plant supporting the design with an attached steam superheater, but the evaporation is too large for most of China’s steam refining plant does not apply . Medium and small steam Lianxiang plant Nissan Rosin 15-60 tons, usually only 1-4 tons of steam / hour, so generally choose to transport and install convenient, compact and fast boilers to produce steam. however
