Customized Coal Pulverizing System for Power Plants: Design & Solutions

Introduction

Modern power plants demand highly efficient coal pulverizing systems to ensure optimal combustion efficiency and environmental compliance. This article explores advanced design methodologies and tailored solutions for coal pulverization, with a focus on cutting-edge equipment selection and system integration.

Key Requirements for Coal Pulverization

Effective coal pulverization systems must address three critical factors:

  1. Precision Particle Size Control: Consistent fineness (typically 70-90% passing 200 mesh) for complete combustion
  2. System Reliability: Continuous operation with minimal downtime
  3. Energy Efficiency: Reduced specific power consumption per ton of processed coal

System Design Considerations

1. Material Characteristics Analysis

Successful system design begins with comprehensive coal analysis:

  • Hardness (HGI index measurement)
  • Moisture content (surface vs. inherent moisture)
  • Ash fusion characteristics
  • Grindability test results

2. Equipment Selection Matrix

Our technical evaluation recommends two superior solutions for different capacity requirements:

Solution A: LM Series Vertical Roller Mill

For medium to large power plants (15-250t/h capacity):

  • Integrated drying/pulverizing system reduces pre-processing
  • Energy savings up to 40% compared to ball mills
  • Compact footprint reduces construction costs
