CFB boiler special coal pillar crushing and sorting machine introduction

在CFB boiler technology in the application, supportingTraditional coal crushing equipment的问题It is mainly reflected in the following aspects:

（1）碎煤System production of finished coal particle size andCFB boilerCounter coalThe grain size demand does not match, the particle size is too large or too small, resulting in low combustion efficiency of coal;

（2) The coal used in the power plant has a high sulfur content, a large moisture content, and a strong adhesion, resulting in crushing equipment and coal pipeline easy to braise and clog, the system运行Not stable;

（3）To reduce the cost of burning coal,The proportion of mixed coal gangue with low calorific value is increasing continuously.Coal gangue is not easily broken导致Coal crushing system to produce finished coal seriously coarse，The combustion efficiency, energy saving, environmental protection and operation stability of the boiler are greatly affected；

（4) The traditional coal breaking equipment technology is relatively backward, with large noise, large vibration and other defects, it is difficult to adapt to the increasingly high environmental requirements。

Changsha Shenxiang General machine Co., LTDLong-term commitmentChina high-end broken碎装备Its systematic研发与生产。To solveCFB boiler power plant available碎煤Problems with the system,Changsha Shenxiang General machine Co., LTDprocreativeCFB boiler coal pillar crushing and sorting machineSeries products, with ideal product particle size, stable output, low failure rate, strong adaptability to coal adhesion, low noise and vibration performance characteristics, forCFB boiler power plantCoal burning碎systematicProvides a new solution方案。

二、Column crushing and screening of integrated coal crusherWorking principle

Column crushing and screening of integrated coal crusherOn the one hand, the roller is used to carry out the material搓揉、Crushing and striking, on the other hand, are carried out side crushing and side pushing screeningHigh efficiency grinding原理。In addition to the powerful crushing medium, the crushing chamber also has a set of devices for pushing the material。已被破碎Up to standard粒径的燃煤颗The crushing chamber is discharged in time by the extrusion device，Coal that does not meet the particle size requirements of the finished product is transferredDevice side push forward移The edge is crushed and struck by the roller until it is broken到合格Post-particle sizeBe squeezedDischarge crushing chamber。

3. Solve problems

1、CFB boiler special coal pillar crushing and sorting machine crushingThe particle size of the finished coal can fully meet the requirements of the boiler≤10mm、≤8mm、≤6mm、≤5mmAnd the particle size distribution fully meets the requirements of the boiler for the coal particle size distribution curve；

2、First order crushing，原Coal size from200mmStraight through the column crusher one stageBreak to≤8mm, pass rate achieved95%以上；

3、It has strong adaptability to the humidity and viscosity of raw coal. When the water content of raw coal is high or the viscosity is relatively large, the column crusher will not block or suffocate；

4The preparation system works under negative pressure, no coal dust flying, low production noise and working environment保护好；

5The system process is simple, less equipment, and the operation, maintenance and reliability of the system are greatly improved;

6、CFB boiler special coal pillar crushing and sorting machine coalPreparation systemCompared with the traditional crusher coal preparation system节电30%Above, and the wearing parts have a long service life；

7、Compared with the traditional two-break and three-screen processSignificantly decrease了Power plant investment成本。

四、CFB boiler coal pillar crushing and sorting machineTechnical parameter(Calibration material: coal 70%, coal gangue 30%, product particle size of d85)
