Abstract

The invention discloses a steam recycling method. The method includes an economizer, an evaporator, a steam overheating device and a heat exchanger which are sequentially arranged in a flue of a heating furnace. A softened water tank is connected with the economizer. The economizer is connected with steam pockets. The steam pockets are connected with a steam discharge main pipe through steam discharge branch pipes. The steam discharge main pipe is connected with the steam overheating device arranged in the flue of the heating furnace. The steam overheating device is connected with a hot steam discharge main pipe which is connected with an intelligent power generator set. The intelligent power generator set is connected with an electricity receiving cabinet of the heating furnace and a power network. By means of the steam recycling method, waste heat of smoke of the heating furnace can be utilized to the maximum extent, all steam produced by the heating furnace is used for meeting the production requirements of electricity-consuming devices of the heating furnace, and therefore all the devices of the heating furnace can achieve self-sufficiency of electricity, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the field of recovery and utilization of waste heat, in particular to a method for recovery and utilization of steam. Background technique [0002] In the field of industrial furnaces, after the flue gas in the industrial furnace passes through the heat exchanger installed in the flue, the exhaust gas temperature is generally about 400°C, and the waste heat in this part of the flue gas is usually not recovered, but directly discharged into the atmosphere , resulting in a great waste of energy; in the field of industrial furnaces, the power supply of heating equipment is usually supplied by the external network. For large joint enterprises, the power supply of heating equipment is usually set to two power sources, one for production power and the other for security power; for small private enterprises, the power supply of heating equipment is usually set to one for production power. Set security power. This poses a safety haza...
