Cohen, H T

This patent describes a process for the manufacture of water gas by a cyclic process in which an ignited fuel bed in a generator is alternately blasted with air to raise its temperature and then steamed to produce water gas. The steps consist of passing the blast gases from the generator into a heat-recuperating zone containing firebrick checkerwork, introducing secondary air and burning the hot blast gases in the said recuperating zone and storing a part of the heat therein, and passing the gases from said recuperating zone into a second heat-recuperating zone containing metallic heat-absorbing material to absorb residual heat from the blast products whereby the hot blast gases are cooled by the heat absorbing material. The blast gases are cooled and rendered nonluminous to be discharged to the atmosphere. The process continues by terminating the blow or air-blasting period, spraying water on the metallic material after cessation of the blow or air-blasting period to generate steam from the sensible heat of the heat-absorbing metallic material, and passing said steam over the firebrick checkerwork in the first mentioned recuperating zone to superheat the steam. The superheated steam is passed through the generator to effect a backrun.
