脱硫系统不设烟气再热器方案探讨
摘要
脱硫系统较多采用设置烟气再热器(GGH)方案。GGH可以降低吸收塔的入口烟温
提高烟囱出口烟温和烟气抬升高度
但也存在初投资大、运行维护费用高等问题。为此
从技术、经济及环保角度对脱硫系统GGH设置与否进行了比较
探讨了不设GGH方案的可行性
并给出了相关建议。
Abstract
A scheme with installation of gasgas heater(GGH) has been more frequently adopted in the desulfuration systems.The GGH can reduce the inlet gas temperature of absorption tower
enhance the outlet gas temperature from chimney
and raise the height of flue gas
but some problems
such as large capital investment
high operation and maintenance cost etc.
are still existing.For this reason
the desulfuration systems with and without installation of GGH have been compared from aspects of technology
economy
and environmental protection
the feasibility of scheme without installation of GGH being discussed
