Waste heat power generating system for ISA furnace and converter furnace

Abstract

The invention discloses a waste heat power generating system for an ISA furnace and a converter furnace and relates to waste heat power generating systems. The waste heat power generating system comprises the ISA waste heat furnace, the converter waste heat furnace, an intermediate pressure steam balance pipe and a waste heat power generating station, wherein the ISA waste heat furnace and the converter waste heat furnace are arranged on the intermediate pressure steam balance pipe in parallel; a first isolation valve is arranged at the output end of the intermediate pressure steam balance pipe; the waste heat power generating station is installed at the output end of the intermediate pressure steam balance pipe and provided with a water delivery pipe; and a salt removal water tank is arranged at the output end of the water delivery pipe. By means of the waste heat power generating system, loads in the converter waste heat furnace can be kept to be stable, the converter waste heat furnace can also generate extra steam in the blowing process, and the steam is conveyed into the waste heat power generating station for power generation, so that energy is reasonably utilized, and energy waste is prevented.

Description

technical field [0001] The invention relates to a waste heat power generation system, in particular to a waste heat power generation system for an ISA boiler and a converter boiler. Background technique [0002] In the process of using the converter for steelmaking, a large amount of high-temperature converter gas will be produced, and the vaporization cooling device of the converter gas waste heat boiler can generate steam. Due to the discontinuity of the converter steelmaking process, the operation of the converter changes periodically, and the steam generated by the sensible heat of the converter gas is also discontinuous. At the same time, the parameters of the steam are low, and the pressure and temperature have certain fluctuations. Low parameters and low quality steam. As iron and steel enterprises attach importance to energy saving and emission reduction, various waste heat recovery technologies have been promoted in iron and steel enterprises, and more and more low...

AI Technical Summary

Problems solved by technology

As iron and steel enterprises attach importance to energy saving and emission reduction, various waste heat recovery technologies have been promoted in iron and steel enterprises, and more and more low-parameter and low-quality steam are obtained by using various waste heat recovery technologies. However, the steam generated by the waste heat boiler has not been effectively utilized, resulting in most of the steam being evacuated

The dissipation of steam leads to the loss and waste of a large amount of heat and working fluid (demineralized water), resulting in high energy consumption costs of our factory, and the direct discharge of steam also produces relatively large noise pollution
