Abstract

The invention discloses a control system and a method for the steady-value voltage stabilization of the mixed gas. The control system comprises a coke oven gas source and a blast furnace gas source, the coke oven gas source and the blast furnace gas source are connected with a first caliber branch and a second caliber branch which are connected in parallel through corresponding supply branches, the first caliber branch and the second caliber branch are merged to form a mixed branch; flow meters and flow regulating valves are arranged on the first caliber branch and the second caliber branch, aheat value instrument is arranged on the coke oven gas source and the blast furnace gas source supply branch and the mixing branch. According to the control system, a given amount of a flow regulating valve on each caliber branch is controlled through a mode of combining feedforward control with a double-closed-loop ratio control system, so as to adjust the heat value and the pressure of the mixed gas.

Description

technical field [0001] The invention relates to a control system and method for stabilizing the heat value and voltage of mixed gas. Background technique [0002] The iron and steel industry will produce a large number of by-products in the production process of ironmaking, steelmaking and coking - blast furnace gas, converter gas and coke oven gas. The by-product gas is recycled and used as fuel for waste heat power generation, lime kiln, heating furnace and other process equipment. Because the calorific value of the by-product gas does not match the calorific value required by the process, the industry generally adopts the method of gas mixing to deliver mixed gas with stable calorific value and pressure to the process production unit. [0003] The traditional mixing station simply takes the calorific value of the mixed gas as the controlled parameter, mixes the gas with low calorific value and gas with high calorific value in a certain proportion, and finally delivers it...
