在废热回收中考虑的第一步,是考察整个装置的情况,并在排出的能量中全部可回收的能量。考察中必须包括温度、流量、固体颗粒、腐蚀和可凝汽体等因素。工艺过程和燃烧设备的排出能量,是可回收能量的主要来源,由于排放废热较工艺过程和燃烧设备的工作温度低得多,因此只有在最大限度地利用工艺过程和燃烧设备的能量后,才考虑作为一种能源加以利用。 The first step considered in waste heat recovery is to look at the condition of the entire plant and to recover all of the energy that can be recovered. The investigation must include such factors as temperature, flow, solid particles, corrosion, and condensable vapors. The discharge energy of the process and combustion equipment is the main source of recoverable energy. Since the exhaust waste heat is much lower than the working temperature of the process and combustion equipment, it is only after maximum use of the energy of the process and combustion equipment. Consider using it as an energy source.
