METHOD AND APPARATUS FOR DISCHARGING SLAG FROM GASIFICATION REACTORS

摘要

The invention relates to a method of evacuating ash and slag from reactors for pressure gasification of fuels, said fuels including coals of various ranks, cokes or ash-containing liquids or liquid-solid suspensions, at pressures between ambient pressure and 80 bar at gasification temperatures ranging between 800 and 1,800 °C, a water circuit (10) for loosening the deposited slag (8) being maintained between a gasification chamber (3) downstream of which there is mounted a quench chamber (5) to which there is connected a slag lock hopper (7) and circuit water being supplied to the upper and lower part of the quench chamber (5), and to an apparatus for carrying out said method (Fig. 1)
