Document Type and Number:
WIPO Patent Application WO/2013/094553
Kind Code:
A1
Abstract:
Provided is a firing furnace capable of stably recovering exhaust heat energy over a long period of time by using a Stirling engine. Stirling engines (20) are provided in a cooling zone (5) of a roller hearth kiln (1). High temperature side heat-exchanging units (21) of the Stirling engines (20) are inserted below a roller (2) through through-holes (12) provided in the left and right walls of a furnace body (10). A power generator is driven by the Stirling engines (20), and the exhaust heat energy is recovered as electric power.
