Focus on heavy equipment
A Shandong company specializes in the production of wood biomass pellet fuel. It originally used natural gas hot air furnaces to dry sawdust, wood chips and other raw materials (initial moisture content 35%-55%). However, after considering reducing production costs, the company built a new high-efficiency pulverized coal hot air furnace system with a multi-stage heat exchange device specifically for biomass raw material drying production lines.
1. Obvious fuel cost advantage
Compared with natural gas, the cost of coal is only 1/3-1/2.
2. High temperature and stable heating capacity
It can stably provide 600-1000℃ high temperature hot air, and the temperature fluctuation is controlled within ±5℃, which can meet the needs of rapid drying of various high-moisture materials.
3. High energy utilization efficiency
The coal powder combustion efficiency is more than 92%, and the comprehensive thermal efficiency can reach 85% after matching the waste heat recovery system, which saves more than 30% energy compared with traditional coal-fired boilers.
The case of pulverized coal furnace fully demonstrates that pulverized coal furnace has significant economic and environmental benefits in the field of biomass drying, and provides an efficient and environmentally friendly heat source solution for the drying industry.
