Abstract

A burning controlling apparatus and a burning controlling method capable of performing a variable control having a stable furnace temperature and / or burning atmosphere by a relative simple configuration. A roller hearth kiln is comprised of a high temperature air feeding device, a reducing combustion flame generating device, and a combustion discharged gas processing device. These devices are provided with a supplying gas feeding passage and a combustion discharged gas feeding-out passage. The devices are further provided with a first heat exchanger, a second heat exchanger, a first combustion region, a second combustion region, a flow dividing region / a flow merging region. A flow passage changing-over device is connected to a fed air feeding passage and a combustion gas discharging passage, and communication passages HA, HB and HC are connected to a color generating zone or a reducing zone.

Description

technical field [0001] The present invention relates to a firing control device and a firing control method, more specifically, to a firing control device and a firing control device capable of arbitrarily controlling the firing temperature and / or firing atmosphere in a kiln for firing ceramics, etc. control method. Background technique [0002] In the prior art, industrial firing kilns are widely used. The industrial firing furnaces are used for firing blanks of ceramics and the like, and for manufacturing various ceramic products such as ceramic tiles for interior and exterior decoration of buildings. The kiln includes, for example, continuous firing furnaces such as tunnel kiln (TK) and roller hearth kiln (RHK), as well as intermittent firing furnaces of various structures such as intermittent single kiln (shuttle kiln). . [0003] In such a firing kiln, the predetermined firing mode temperature conditions and the environment inside the furnace are set to be suitable fo...
