Disgrifiad o'r Nodweddion
Mewn cylchred cyfunol, bydd gwres gwastraff y tiwb yn cael ei ailgylchu gan HRSC ac yn cynhyrchu ager i gynhyrchu trydan. Mae tiwbiau hir iawn HRSG yn brif gydrannau HRSG. Roedd gan ein cynnyrch gwmpas gwahanol feintiau. Mae gennym lawer o dystysgrifau ac allforio mwy na 10 mlynedd.
