Pulverized Coal Injection
CISDI is one of the world’s leading PCI system providers, having more than 50 references in the last 40 years. Technical advantages of using CISDI PCI systems:
-
Unique pulverization system:
Stove off gas or other waste gases can be used as the drying medium for coal pulverisation. This leads to reduced energy consumption and lower emissions.
-
Low-speed dense-phase transport system:
The pulverised coal is transported in a small amount of additional gas at low speed in the dense phase, with a 40kg/kg solid-gas mass ratio. This is favourable on injection into the blast furnace.
-
Long-distance transportation:
CISDI is capable of providing coal injection mains that feed directly into the blast furnace over 1200m in length.
-
Even coal flow at tuyeres:
PCI system is designed with an equal pressure drop in each branch, balancing the coal flow at each of the tuyeres.
