由于国内大型钢企普遍引进CCPP(燃气蒸汽联合循环发电机组)装置,占用了大量的高炉煤气,导致他们的轧钢加热炉不得不烧高焦炉混合煤气。通过将某Y厂中板加热炉采用蓄热式技术获得的效益与某A厂采用300MWCCPP装置获得的效益进行比较,认为CCPP技术应该逐步退出历史舞台。
Due to the widespread introduction of CCPP (gas-steam combined-cycle power plant) installations by large steel enterprises in China, a large amount of blast furnace gas is taken up, resulting in their rolling furnaces having to burn high-coke oven mixed gas. By comparing the benefits obtained by thermal storage technology of a Y plate medium furnace with those obtained by a 300 MW CPP plant at a plant A, the CCPP technology should be gradually withdrawn from the historical arena.
