Abstract

The invention relates to a utilization system of dead steam heat of a power plant. The utilization system comprises a boiler, a steam turbine, a condenser, a heat pump, a peak load calorifier and a secondary heat exchange station, wherein the steam turbine is connected with the condenser through an exhaust pipe; a steam extraction pipe is arranged on an air inlet pipe of the steam turbine; a low temperature heat source inlet of the heat pump is connected with a water outlet of the condenser; a lower temperature heat source outlet of the heat pump is connected with a water return port of the condenser; a driving heat source inlet of the heat pump is connected with the steam extraction pipe; a condensate outlet of the heat pump is connected to the boiler; a water supply outlet of the heat pump is connected with a water inlet of the peak load calorifier; a water outlet of the peak load calorifier is connected with a heat source inlet of the secondary heat exchange station through a pipeline; a heat source outlet of the secondary heat exchange station is connected with a water supply inlet of the heat pump; a water inlet of the secondary heat exchange station is connected with a water supply source; and a water outlet of the secondary heat exchange station is connected with a heat utilization device. The utilization system can well adapt to an existing power plant heat supply unit and can utilize dead steam waste heat of the steam turbine, thereby achieving the purposes of energy conservation and consumption reduction.

Description

Technical field [0001] The invention relates to the technical field of waste heat recovery in thermal power plants, and in particular to a technology for recovering waste heat from exhaust steam of a steam turbine. Background technique [0002] Under the general trend of energy conservation and emission reduction, it is imperative to recover waste heat from the exhaust steam of heat supply units in thermal power plants. There are more and more waste heat projects of waste steam in power plants, and the investment in this optimized design of heat supply units is huge. Moreover, most of the exhausted steam waste heat recovery projects that have been implemented and completed did not play the expected effect in actual operation, and most of the exhausted steam waste heat projects were not suitable for existing heating units during design and operation. Up to now, no guidance documents have been issued for waste heat recovery projects of power plants in the industry. [0003] In view ...
