GGH: Non-leakage type

GGH can be largely divided into the Rotary(Ljungstrom) type and non-leakage type. In contrast to the rotary type, which has a limit in lowering the concentration of harmful gas emissions due to internal leakage, the non-leakage type uses a tube as a heat inside. Due to the structural nature of circulation, no leakage occurs. It has the advantage of minimizing the concentration of emitted air pollutants. However, this also causesproblems such as ash cutting, clogging, differential pressure rise, and performance degradation due to coal ash and ammonia, and our products boast a longer lifespan than Non-Coating products or other coatings.
