Horizontal Oil Gas Dual Fuel Fired Steam Boiler

Certification: GB, ISO, ASME, CE, ECA
After-sales Service Provided: Engineers available to service machinery overseas
Voltage Used Widely: 220-460V/50-60Hz
Electric Control: Fully automatic
Rated Steam Temperature: 170-204℃
Design Efficiency:≥94%


Boiler Features:
1. This series boiler adopts vertical through flow and three-pass furnace.
2. The burner is down-fired type.
3. The flame can completely spread from the top down to make burning full.
4. The gas need to make a three-return heat transfer, so the heat loss will be reduced and the thermal efficiency will be higher.
5. At the same time, this series boiler have the controller protection device, and contact device to automatic recovery prevent to get an electric shock , through the exhaust thermal protection device, strengthen the safety and function.

Boiler Advantage:
1.Safety: with water level, leakage steam, steam pressure control. Make sure boiler working safety.
2.Product quality ensured by: strength calculation report, hydraulic test, X-ray, non-destructive test.
3.Efficient: well insulation and excellent structure.
4.Spirally corrugated tube increase the strength and also meets the needs of heat expansion of each parts.
