| Abstract:Using black liquor gasification gas to substitute a part of fuel for paper sheet drying could save the cost of fuel and increase economic efficiency and competitiveness of the enterprise. A design scheme of black liquor gasification combined with paper sheet drying was formulated in this paper. The equipments of the project consisted of black liquor gasification system and paper drying system. The technological process was designed as the follows：the gasification gas was produced in the gasifer, and consequently treated with cooling and desulfurization, thereby the purified gasification gas was obtained. The purified gas could be burned as fuel in furnace to heat up the air to 230～240℃. Then the hot air was blown to the wet sheet on the surface of dryer via a heated air hood to increase drying rate of the paper sheet. |
