This design effectively increasing smoke heat transfer to boiler water, which, improving thermal efficiency and good at engergy saving. No pipe design could save boiler from scaled and destroyed. The heat evenly transfer to wall and fins, avoiding stress and extending service life. Compared with similar products, LWS series has large combustor room and low out-let temperature. The thread smoke tubes are mainly convective heating surface. ”
