Abstract
This paper numerically simulates the combustion in a 300MW tangentially fired pulverized high-alkali coal boiler under low-load conditions. The
combustion process, temperature distribution and the thermal load in the furnace at different height are analyzed under three different load conditions,
which are 30%, 45% and 60% of full load. The temperature distribution and the variation of NO
x concentration under different load conditions are
investigated, as well. The results show that the combustion processes of pulverized high-alkali coal in the furnace are similar under different load
conditions, but the positions of the fuel’s full combustion are related to the loads. With the load increasing, the high temperature area gradually expands
from the burner area to the central area of the furnace and extends to the upper part of the furnace. The distribution of NO
x concentration is significantly
related to the loads. The distributions of NO
x concentration at 45% and 60% of full load are roughly similar, and mainly concentrate in the areas near
the burner and up the burner area, which are the high temperature regions. But the distribution of NO
x at 30% of full load mainly concentrates in the
upper part of the furnace, while the NO
x concentration in the burner area is relatively low.
