Abstract
A gasification system according to an aspect includes a scrubber device to transfer contaminant contained in a flammable gas to cleaning water and discharge the cleaning water containing the contaminant as scrubber wastewater, a heat exchange device to heat the scrubber wastewater to vaporize the contaminant contained in the scrubber wastewater; and a combustion furnace to incinerate the vaporized contaminant, wherein the heat exchange device heats the scrubber wastewater by using heat generated by the combustion furnace.
Claims5
A gasification system comprising:
- a scrubber device to transfer contaminant contained in a flammable gas to cleaning water and discharge the cleaning water containing the contaminant as scrubber wastewater;
- a heat exchange device to heat the scrubber wastewater to vaporize the contaminant contained in the scrubber wastewater;
- a combustion furnace to incinerate the vaporized contaminant;
- a gasification furnace to generate the flammable gas from biomass fuel by using heat generated in the combustion furnace;
- and
- a boiler to generate hot water by using exhaust heat of the gasification furnace,
- wherein the heat exchange device heats the scrubber wastewater by using the hot water generated by the boiler,
- wherein the heat exchange device includes:
- a hot water tank to store the hot water;
- a heat exchanger provided in the hot water tank to heat the scrubber wastewater through heat exchange between the hot water and the scrubber wastewater;
- and
- a retaining tank to store the heated scrubber wastewater.
