Application of Wear-Resistant Alumina Liner in Power Plant

In the power plant pulverizing system, dust removal system, coal transport system will appear serious steel wear, which will affect the power plant is in pulverizing system, dust removal system, coal transport system in the normal use, after the use of a variety of materials, wear-resistant aluminum oxide lining plate good performance is higher than other. 

Wear-resistant ceramic lining board is a new type of special corundum ceramics combined with inorganic special binder.  Wear-resistant alumina lining board has the following characteristics: 

1. Aluminum oxide lining board hardness, high strength;

2. Compared with other materials, wear-resistant alumina lining board has good wear resistance and long service life; 

3. Easy to install, can install various shapes of equipment;

4. Wide application range and strong adaptability.

There are a wide range of equipment systems that can be used for wear-resistant alumina ceramic linings, including coal handling systems: can be used for air locks, raw coal bunkers, coal drop buckets, coal drop pipes, and drum lagging;

Powder system: medium speed coal mill cylinder, separator outlet pipe, filling elbow, separator inner cone, guide vane, etc.;

Desulfurization system: it can be used for limestone pipeline; powder feeding system: dust removal shell, dust removal impeller coal powder pipeline, thermometer protection sleeve, coal powder mixer, throttling shrinkage hole, etc.;

Dust removal system: It can be used for air preheater support rod, preheater baffle, preheater pipe wall, induced draft fan shell, flue pipe wall and other equipment;

Injection system: it can be used for the cone body equipment of pulverized coal concentrator, and the equipment of pulverized coal concentration and dilution separator;

Grease discharge system: ash discharge pipe, dry ash fan casing, fan impeller, valve and cylinder wall, slag pipe; steel ball coal mill: can be used for coal mill outlet pipe equipment, sawdust separator, coarse and fine powder separator equipment, powder return Pipes and other equipment.
