Focus on heavy equipment
Shanxi Mining Company has an annual production capacity of 500,000 tons of iron ore concentrate. The original coal-fired direct-heated hot air furnace with a rotary dryer has problems of high pollution and high energy consumption. Therefore, after the transformation, the 10t/h biomass hot air furnace system was adopted to achieve the dual goals of clean production and cost optimization.
Advantages of biomass hot air furnace
1. Environmental performance
Using forestry waste (pine sawdust, fruit shells, etc.) as fuel, it reduces CO₂ emissions by 28,000 tons/year compared with coal-fired furnaces.
2. Fuel economy
The local biomass fuel price is only 60% of coal, and 40% of the tailings sludge produced by the ore dressing plant can be mixed.
3. Automatic adjustment:
The furnace temperature is adjusted according to the moisture content of the ore (12%→3%), the hot air temperature is stabilized at 550±10℃, and the air volume automatically matches the dryer speed
4. Convenient maintenance
Original spiral dust removal device, online decoking system
