Abstract

The invention discloses a method and application equipment for desulphurization in a furnace of a boiler with desulphurization ash in a semi-dry process. The dried desulphurization ash is produced in the semi-dry process, a path of pipe is additionally arranged on the pipeline of transporting the dried desulphurization ash by the pump, and the dried desulphurization ash is delivered to a furnace of the boiler or the coal feeding port on the boiler to carry out in-furnace desulphurization reaction. The dried desulphurization ash can be recycled in the method provided by the invention, thus the problem of wasting absorbent is solved, the desulphurization ash is more facilitated for utilization, and the desulphurization cost of a electric power plant is effectively lowered.

Description

technical field [0001] The invention relates to a method for using semi-dry desulfurization ash in a boiler furnace for desulfurization and equipment used, belonging to the technical field of desulfurization. Background technique [0002] With the development of science and technology, human beings' demand for energy is getting higher and higher, and the consumption of natural resources is getting faster and faster, so people start to advocate energy conservation and emission reduction. [0003] In the prior art, in the flue gas purification process of the power plant, the semi-dry flue gas desulfurization will generate dry desulfurization ash, which is discharged from the bag filter and then transported to the warehouse pump, and then the warehouse pump transports the dry desulfurization ash To the ash storehouse, since the dry desulfurization ash contains desulfurization reaction products, fly ash and unreacted absorbent, the unreacted absorbent accounts for 10% to 30%, wh...
