SZS Oil Gas Boiler Features

Larger Comubustion furnace
Enough big combusition space, gas/oil burning sufficiently. Quick running, strong power to steam generating with 10minutes.
Membrane type water wall structure
Whole membrane type water wall structure is adopted around the furnace, has good sealing performance, low heat loss, no smoke and smoke leakage.
Higher quality steam generation
Compared with fire tube boiler, szs water tube boiler generating higher quality steam for using. (Moisture content<3%)
Saturated Steam & Superheated Steam
SZS series boiler can generate superheated steam for higher temperature compared with fire tube boiler, to reach different processing demand.Technical Parameter
