Abstract: The system comprises a boiler (1), main burner groups (2F, 2E, 2D, 2C) located on different levels or zones through which pulverized solid fuel is injected into the boiler (1) and main mills (3F, 3E, 3D, 3C) for solid fuel, where each of them is connected to one of the main burner groups (2F, 2E, 2D, 2C) to which a flow of solid fuel

Numerical calculation with detailed chemistry on

A pulverized coal-fired boiler was simplified and expressed as a reactor network, which comprised a burner zone, an over-fire zone, and two downstream zones using PSRs. The NH 3 co-firing ratio was varied from 0% to 80%, where 0% represents pure coal firing. NH 3 was injected into the flame zone in the burner

As small to medium coal-fired boilers, CPC can significantly reduce NOx emissions while maintaining the compactness of the boiler on a scale similar to that of an-oil fired boiler. It can recover all the coal ash as molten slag. Figure 1 shows a schematic drawing of a atmospheric pressure CPC boiler.
