Pulverized Coal Injection for Blast Furnace

Reducing the coke rate of the blast furnace and the cost of pig iron dramatically.
Regulating the thermal system of furnace condition effectively.
Strengthening the reducing capacity of coal gan and developing the indirect reducing capacity.
Letting the working position of hearth run steady and smoothly.
Creating condition for blast furnace to use the high blast temperature.
The high pulverized coal injection rate can increase the economic benefits, reduce the energy consumption, change the energy structure and low the environmental pollution, etc.
After stoving and levigating, the row coal including soft coal and blind coal is conveyed by the compressed air or nitrogen before being injected into hearth by coal lace from the blast furnace.
Adopting this craft simplifies the process and saves investment.
The new closed combustion-gap furnace makes the most of exhaust gan and saving resource.
The medium speed mill reduces the cost of pulverized coal.
The low voltage impulse pulverized coal collector simplifies the technological process, increases the collection efficiency and reducing the environmental pollution.
Fully automatic control adjusts the quantity of pulverized coal injection.
Each ton of iron needs the quantity of coal more than 150kg, and the period for recovery of investment is less than 3 months. For example, a 380m3 blast furnace saving 150, 000 yuan each day.
