The oil/gas-fired steam boiler is a shell-type full wet-back straight-flow three-pass fire-tube design; flames burn with slight positive pressure and full expansion in the large combustion chamber for low heat load and low NOx emissions. Yongxin boiler’s corrugated furnace and threaded smoke tubes boost strength and accommodate thermal expansion of heated parts.
