High-temperature pellet direct waste heat recovery device - Product

Our company began to study the direct waste heat recovery technology of high-temperature solid materials in 2011. After years of theoretical research and cold and hot pilot tests, we successfully achieved the first set of engineering application in the waste heat recovery of semi-coal in 2013, and successfully achieved the first set of engineering application in the waste heat recovery of pellets in 2021.

High-temperature pellet direct waste heat recovery process

Through one-time heat exchange, directly recover pellet waste heat to generate high-quality superheated steam for power generation, heating or other industrial applications

No intermediate heat exchange medium, environmentally friendly and pollution-free

The pellets do not fall to the ground or transported in reverse, and the factory environment is good

One-time heat exchange, less heat loss, high heat recovery efficiency

Low self-consumption, high net power generation, short investment return period, reduce pellet breakage rate, improve pellet strength, fully automated and intelligent operation, simple operation and maintenance
