一、前言随着我国工业经济的发展,工业能耗日趋增加,工业领域能源消耗量约占全国能源消耗总量的70%左右。除了生产工艺相对落后、产业结构不合理的因素外,工业余热利用率低,能量没有得到充分综合利用是造成能耗高的重要原因。节能减排、降低能耗、提高能源综合利用率是我国能源发展战略规划的重要内容,是解决我国能源问题的根本途径。通过回收生产工艺过程中的余热,产生蒸气或热水用于发电并网或者满足生产生活的其他热能需求,
I. Introduction With the development of China’s industrial economy and the increase of industrial energy consumption, the energy consumption in the industrial field accounts for about 70% of the total energy consumption in China. In addition to the relatively backward production technology and irrational industrial structure, the utilization rate of industrial waste heat is low, and the lack of full utilization of energy is the important reason for high energy consumption. Energy-saving and emission reduction, reducing energy consumption and improving energy utilization rate are the important contents of China’s energy development strategic plan and the fundamental way to solve China’s energy problems. Through the recovery of waste heat in the production process to produce steam or hot water for power generation and grid or to meet other production and living needs of heat,
