Abstract

The utility model discloses a device utilizing smoke of an economizer to heat condensation water for waste heat generation, belongs to waste heat utilization equipment, and particularly relates to a waste heat utilization device of high-temperature smoke exhausted from an economizer. The device comprises an economizer, a deaerator and a condensation water pump, and is characterized in that a smoke outlet of the economizer is connected with a smoke inlet of a smoke-water heat exchanger via a pipeline, a smoke outlet of the smoke-water heat exchanger is connected with a chimney, the condensation water pump is connected with a cold water inlet of the smoke-water heat exchanger via a pipeline, and a hot water outlet of the smoke-water heat exchanger is then connected with the deaerator via a pipeline. Temperature of condensation water is increased by aid of high-temperature smoke exhausted from the economizer. As the temperature of condensation water can be increased from 37 D EGC to 87 D EGC, deoxidation effect can be increased, heating steam usage is reduced, and steam volume and power output of a steam turbine are increased. In addition, two 3000kW generation units can save at least 2000 tons of reduced standard coal every year, thereby achieving obvious economic benefit.

Description
