Abstract

A combined, integral steam generator coal gasifier includes a vertically elongated, all welded, gas tight enclosure with a burner zone having a double pitch sloping furnace floor and a slag tap extending therethrough.
Successive zones located above the burner zone are provided with appropriate tube materials for conveying synthesis gas produced by the coal gasification process. A multi-pass convection pass zone having upflow and downflow passes is locted at an upper portion of the enclosure and contains a plurality of superheater (primary and secondary) as well as economizer heating surfaces which extract heat from the synthesis gas to produce steam. An ash remover is connected to the outlet of the convection pass zone to remove ash from the synthesis gas exiting from the convection pass zone. The slag tap located at the bottom of the burner zone communicates with a slag tank or a submerged drag chain deasher for receiving and removing slag from the burner zone.
