Decoupling combustion furnace and decoupling combustion method
ActiveCN101650025AIncrease combustion spaceImprove combustion intensityAir supply regulationCarburetting by solid carbonaceous material pyrolysisCombustionProcess engineering
The invention provides a decoupling combustion method, which comprises the following steps: a) firstly, performing pyrolysis and gasification of fuels to generate semicoke and gas; b) secondly, combusting part of gas and semicoke to perform oxidation reaction and reduction reaction to generate coke, and applying the generated heat to the pyrolysis and gasification in step a); c) thirdly, combusting the coke and the left gas generated in step a) under the condition that an excess air coefficient is less than 1, and simultaneously generating smoke in the combustion; and d) finally, performing full secondary combustion of the smoke and the remained gas after the steps. The decoupling combustion method can increase the decoupling combustion space and intensity with a smaller floor area; the increase of the gasification zone and the gasification intensity greatly improve the load increasing capability of a decoupling combustion furnace; and in addition, because the high-temperature smoke strongly heats the fuels in the upper part of a pyrolysis and gasification chamber and has higher pyrolysis and gasification intensity, the gas output is increased and the combustion amount of solid semicoke is reduced.

The system comprises a wet pulverizer, a pressure filter, an equalizing basin, a rotary kiln and an indirect heat exchanger. Desulfurized gypsum, aluminum ash, carbide slag, coal gangue, iron tailings and part of the organic wastewater are mixed to obtain mixed solution, the water content of the mixed solution is 60%-70% (mass), the mixed solution is pulverized by a wet process, wet pulverized materials are equalized to obtain slurry, the slurry is mechanically pressed, filtered and dewatered to obtain paste, the other part of the organic wastewater is concentrated, then enters the rotary kiln together with the paste and calcined at high temperature to obtain base materials, pulverized coal is sprayed into the rotary kiln in the high-temperature calcining process, so that the pulverized coal and organic matters in the mixed paste are burnt, and finally, the base materials, accelerators, dispersants, expanding agents and water are prepared into the ultra-high water filling materials. The system and the method can be used for preparing the novel ultra-high water filling materials by reusing the industrial solid waste.
