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.
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.
