Abstract
The invention relates to a staggered firing for combustion of wet charge materials, consisting of the following steps: pre-combustion designed as a fluidized bed firing, heat transition in a heat exchanger, dust precipitation, and post-combustion. The staggered firing is characterized in that during the heat transition in the heat exchanger, exhaust gases from the pre-combustion are cooled and combustion air for pre-combustion is heated and then supplied to the pre-combustion.
Claims13
Staggered firing for combustion of moist charge materials, comprising:
- pre-combustion in a first combustion chamber designed as a fluidized bed firing, wherein, after pre-combustion, the exhaust gas contains water vapor (H2O), heat transition in a heat exchanger of an air preheater, dust precipitation, and an oxidation of the exhaust gases from the pre-combustion in a post-combustion in a second combustion chamber, characterized in that during the heat transition in the heat exchanger, the exhaust gases from the pre-combustion are cooled and combustion air for pre-combustion is heated and then supplied to the pre-combustion.
