In view of problems existing in velocity of flow monitoring points collocation in circularflue, using hydrodynamics theory to analyze and optimize, one monitoring point at 0.
The circular utilization of the flue gas can lower the air pollution caused by the waste gas exhaust and raise the heat efficiency of furnace and kiln.
The calandria arrangement in the furnace floor flue gas channel that is formed by the ondol pier bricks with circular sections greatly lowers the local resistance loss of flue gas.
