| Abstract: | Two main reasons of water wall slagging, reducing atmosphere and wind powder flow, are studied. Solutions, weakening reducing atmosphere appropriately and preventing the ash melting point from declining, are propoesd. Based on depth discussion of the causes of water wall slagging, the feasibility is analyzed, using SOFA technology. CFD numerical simulation is used to obtain oxygen, temperature and characteristics of formation of nitrogen oxide. The results of simulation provide some guidances for alleviating water wall slagging and applying. |
