Embodiment

[0020] According to the power generation device for comprehensive utilization of converter gas and waste heat steam according to the present invention, and the above-mentioned specific implementation process, three tests were carried out, and the relevant parameters of the three tests are shown in Table 1. The temperature of the accumulator changes during the process of heat storage and heat release, so in the three tests, this parameter is a range.

Abstract

The invention relates to comprehensive utilization of the gas and the steam. The power generation system of the comprehensive utilization of the gas and the steam adds heat storage and branch cylinder, on the basis of the bunker, steam generator, steam drum, superheater and exhaust-heat boiler of the converter. The heat storage connects with the steam drum and branch cylinder respectively. The branch cylinder connects with exhaust-heat boiler of the converter and other fluctuate exhaust-heat. The branch cylinder connects with the steam turbo generator through the superheater to form the intact closed circuit circulation power generation system.

Description

technical field [0001] The invention belongs to the field of converters, relates to the comprehensive utilization of converter gas and waste heat steam, and also relates to power generation power devices. Background technique [0002] In the prior art, the converter gas is not only used for steelmaking and steel rolling heating in the enterprise, but also as a fuel. The surplus converter gas is used to burn steam boilers, and the steam generated is used for power generation. In addition, there are also medium and low-pressure steam produced by the waste heat boiler supporting the converter and steam produced by other waste heat, which is used as the power source of the turbo generator for power generation. However, since the converter gas is periodically changing and unstable, the generated steam flow and pressure also vary greatly, which brings great difficulties to the effective utilization of steam. For this reason, the converter steam of some enterprises is only used in...
