A process and system for producing a H2-containing product gas and purified water from an integrated catalytic steam-hydrocarbon reforming and thermal water purification process. A power supply regulation system includes a transistor through which power is carried. A slave sync generator aligns the PbB and PrR channels to the YG channel by making use of the vertical, horizontal, and timing window sync signals produced by the master sync generator and by generating a slave slice level to detect the vertical and horizontal syncs in the slave channels. Pressure or restriction elements avoid buckling of the lateral edges in the supported part thereof, extending between a first end of the slides, nearest the roll and the roll. Additionally, a first coverage area ratio of the SSL emitters in the central region is different than a second coverage area ratio of the SSL emitters in the peripheral region.
