Executive Summary
Industry: Thermal Power Generation
Problem: Coal pipes wear out in 8-10 months
Solution: Elacera alumina ceramic-lined pipes with an interlocking design
Result: 10x longer service life, 90% less maintenance
The Problem: Why Coal Pipes Fail.
In coal-fired power plants, pulverized coal travels through pipes at high speed (20-30 m/s), eroding steel walls like sandpaper. This leads to leaks, unscheduled shutdowns, and high replacement costs.
In Circulating Fluidized Bed (CFB) boilers, where coal particles are larger and more abrasive, the problem is even worse. Traditional carbon steel pipes typically fail within one year.
The Solution: Elacera alumina Lining Technology
Hunan Yibeinuo New Material Co., Ltd provides high-purity alumina ceramic tiles bonded to pipe interiors using high-temperature inorganic adhesive. The interlocking design prevents direct particle impact on joints, eliminating the straight-line gaps that cause peeling in other linings.
Key Advantages
Extreme hardness: HRA ≥88, second only to diamond.
Temperature resistance: Continuous operation up to 350°C
Impact resistance: Special toughening additives, 2-3x tougher than standard ceramics
Strong bonding: Inorganic adhesive, 8 MPa tensile strength
Lightweight: Density 3.75 g/cm³, less than half of steel
Real-World Case: 300MW CFB Power Plant.
A 300MW CFB power plant in China was replacing carbon steel coal pipes every 10 months. Each replacement cost approximately $15,000 in parts and labor, plus lost generation
After installing the Elacera solution
Product used: 5mm interlocking ceramic-lined straight pipes + 10mm ceramic-lined elbows
18+ months continuous operation with zero failures
90% reduction in maintenance costs
Full ROI achieved within the first year
