摘要

Numerical simulation of the internal flow and heat transfer was conducted in dry slag discharge machine of the boiler in this paper. In the case of constant total air volume, the lateral tuyere layout impact on the inner velocity and ash temperature field was analyzed. The results show that the airflow disturbance of the tuyeres adopting stagger arrangement in the box would be more strengthened than aligned arrangement, and which could reduce high temperature area of the ash layer and protect the security of the steel belt.
