Gasification ash sintered brick and preparation method thereof
The invention provides a gasified ash sintered brick and a preparation method thereof. The gasified ash sintered brick is prepared from the following raw materials in percentage by mass: 20 to 60 percent of gasified coarse slag, 20 to 30 percent of gasified fine slag and 20 to 60 percent of shale powder. In the raw materials of the gasified ash sintered brick, the mixing ratio of the gasified ash is greatly increased, the calorific value of carbon residues in the gasified ash can be fully utilized, heat needed in the subsequent roasting process is self-sufficient, fire coal is not needed, energy is saved, and the carbon residues in the gasified ash are high in ignition point and slow in combustion heat release; non-mechanical cracks caused by green brick stress can be effectively avoided, and then the mechanical strength of the gasified ash sintered brick is improved.
本发明提供了一种气化灰渣烧结砖及其制备方法。该气化灰渣烧结砖按质量百分比计，其原料包括气化粗渣包括：气化粗渣20％～60％，气化细渣20％～30％，页岩粉体20％～60％。本申请提供的气化灰渣烧结砖原料中，气化灰渣掺配比大幅提高，能够充分利用气化灰渣中残炭热值，在后续焙烧过程中所需热量自给自足，不用燃煤，节约能源，且气化灰渣中残炭燃点高燃烧放热缓慢，能够有效避免砖坯应力产生非机械性裂纹，进而提高气化灰渣烧结砖的机械强度。
