TAR REFORMING FURNACE

摘要

Syngas is alternatingly introduced by a syngas alternating lead-in system through either of one- and the other-end-side heat storage bodies into flow passages in a primary reforming furnace, and oxidant is alternatingly supplied to the syngas by a primary-oxidant alternating supply system. The syngas derived from the primary reforming furnace by a syngas alternating lead-out system is introduced into a secondary reforming furnace to which connected is a secondary-oxidant supply system for supply of oxidant only at alternation in the syngas alternating lead-in and -out systems.

主权项

1. A tar reforming furnace characterized in that it comprises
a primary reforming furnace internally formed with syngas flow passages, a one-end-side heat storage body in a one-end-side lead-in-out port of the primary reforming furnace, the other-end-side heat storage body in the other-end-side lead-in-out port of the primary reforming furnace, a syngas alternating lead-in system for alternatingly introducing the syngas through one of the heat storage bodies into the flow passages in the primary reforming furnace, a primary-oxidant alternating supply system for alternatingly supplying an oxidant to the syngas introduced from the syngas alternating lead-in system through the one of the heat storage bodies into the flow passages in the primary reforming furnace, a syngas alternating lead-out system for alternatingly deriving the reformed syngas supplied with the oxidant by the primary-oxidant alternating supply system through the other of the heat storage bodies, a secondary reforming furnace into which is introduced the syngas from the primary reforming furnace through the syngas alternating lead-out system and a secondary-oxidant supply system for supplying an oxidant to the syngas introduced into the secondary reforming furnace only at alternation in the syngas alternating lead-in and -out systems.
