Briefly explain the effects of excessively high or low temperatures in the vaporization furnace on the system Effects of excessive temperature: (1) At high temperatures, the viscosity of the ash decreases, which intensifies the erosion of the refractory bricks. This can lead to cracks, detachment, or even fragmentation of the bricks, reducing their service life. (2) Excessively high temperatures reduce the effective components in the syngas, increase the carbon dioxide content, and raise the specific oxygen consumption. (3) It increases the system’s thermal load, thereby raising the water vapor ratio. (4) When the temperature is too high, the amount of fine ash in the slag increases, as does the amount of fine carbon black in the water vapor, thereby affecting water quality. The effects of too low temperature are: (1) an increase in the viscosity of the ash, making it difficult to remove the ash; this can lead to blockages at the ash outlet and an increase in resistance within the gasification furnace. (2) The carbon conversion rate decreases, affecting the gas production volume.
