Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] Figure 1 ~ Figure 4 Schematically shows a heating furnace waste heat power generation system with vertical low-resistance heat pipes according to an embodiment of the present invention. As shown in the figure, the heating furnace waste heat power generation system with vertical low-resistance heat pipes includes a heating furnace 1, a waste heat recovery device 2, a superheater 5, a steam turbine 6, a generator 7, a condenser 8 and at the tail of the heating furnace 1 along A plurality of first heat pipes 3 are arranged in the flow direction of the flue gas. The evaporation end of the first heat pipe 3 is connected to the flue of the heating furnace 1, and the condensation end of the first heat pipe 3 is connected to the waste heat recovery device 2. The waste heat recovery device 2 is provided with a working fluid inlet flow channel 201 and a workin...

Abstract

The invention discloses a heating furnace afterheat power generation system with vertical low-resistance heat pipes. The system comprises a heating furnace, an afterheat recoverer, a superheater, a turbine, a generator, a condenser, and multiple first heat pipes arranged at the tail part of the heating furnace in the smoke flowing direction; evaporation ends of the first heat pipes communicate with a heating furnace flue; condensation ends of the first heat pipes are connected into the afterheat recoverer; a working medium is arranged in the afterheat recoverer; a working medium outlet runner is connected to an inlet of the superheater; an outlet of the superheater is connected to the turbine; an output shaft of the turbine is connected with the generator; a working medium channel outlet of the turbine is connected with a condenser inlet; a pump is arranged on an outlet pipe of the condenser, and communicates to a working medium inlet runner of the afterheat recoverer; and multiple layers and multiple rows of high-density wire-shaped bent heat exchange pieces are arranged on the surfaces of the first heat pipes. The system greatly improves the heating furnace afterheat utilization efficiency through the first heat pipes, the turbine and the generator, saves the energy, and is green and environmentally friendly.

Description

technical field [0001] The invention relates to the field of recovery and utilization of waste heat and waste energy, in particular to a heating furnace waste heat power generation system with vertical low-resistance heat pipes. Background technique [0002] As a major energy consumer, steel rolling heating furnaces in iron and steel enterprises directly affect the production costs of enterprises. Generally, as a heating equipment, the thermal efficiency of a heating furnace is generally about 30%, and the energy consumption is high and the energy utilization level is low, resulting in a large amount of energy waste. Therefore, recovering the waste heat of the heating furnace has both good economic benefits and certain environmental benefits. [0003] At present, most iron and steel enterprises use vaporization cooling walking beam heating furnaces. The general fuel is mixed gas, and the smoke exhaust method is natural smoke exhaust. The exhaust gas temperature is generally...
