Abstract

According to the system and method for utilizing the waste heat of the high-parameter industrial extracted steam, a high-pressure heater and a small number of valves are additionally arranged, hot re-extracted steam is used for heating boiler feed water for external industrial steam supply, direct temperature and pressure reduction of the high-parameter extracted steam is avoided, gradient utilization of the steam is achieved, and the energy utilization efficiency is improved. According to the method, the transformation range is small, the system is simple, the transformation cost is low, the operation mode of the newly added high-pressure heater is the same as that of an original high-pressure heater, the operation difficulty cannot be increased, throttling losses are remarkably reduced, the boiler feed water temperature is increased, the unit power supply coal consumption is reduced, and the steam supply economical efficiency is improved.

Description

Technical field [0001] The present invention belongs to the field of new energy and energy-saving technology, specifically relates to a high-parameter industrial exhaust steam waste heat utilization system and method. Background [0002] At present, with the construction of a large number of new energy sources such as wind power and photovoltaics, the overall utilization hours of thermal power units have declined significantly, which is not conducive to the reduction of coal consumption for power supply of the unit. According to the in-service thermal power unit in-depth application of systematic energy-saving new technologies, overall planning to achieve energy cascade utilization, vigorously promote energy-saving upgrading, reduce the requirements of system energy consumption transformation, in all means of reducing coal consumption, cogeneration transformation is one of the means to effectively reduce the coal consumption of unit power supply, especially for power plants in t...
