Technical parameter

Oil gas fired boiler could burn both liquid fuel and gaseous fuel. The liquid fuel could be heavy oil, light oil, diesel, furnace oil, bunker oil, LPG (liquefied petroleum gas), etc. The gaseous fuel could be natural gas, city gas, bio-gas, etc.What are the available fuel for the oil gas fired boiler?

Whether the boiler can burn dual fuel or multi-fuel?

Steam boiler have oil burner, gas burner, and oil&gas dual fuel burner, we can offer the specific burner based on customers’ requirement.

What is the texture of spirally corrugated tube?

The texture of spirally corrugated tube is 20#.

The brand of burner?

The brands of burner are Italy Baltur, Rellio, Elco, etc.

What is the thickness of combustion chamber?

the thickness of corrugated furnace is different based on working pressure and furnace diameter, generally, the thickness is between 10~18mm, large combustion space, and combustion sufficient.

What is the advantages of fire tube boiler?

This fire tube boiler has compact structure and convenient operation, strong load adaptability, lower water quality requirement, and the failure rate of it is lower than 0.1!

Details of electric control cabinet.

Electric control cabinet adopts PLC touch screen, display in English. It shows working condition details of boiler, such as water temperature, water pressure, exhaust gas temperature, and over-pressure alarm, etc. In addition, the cabinet is used for set up the parameter, record and analyze the operation data, etc.

What is the inlet pressure of gas burner?

The inlet gas pressure is different for different capacity boiler, for example, the pressure for 2 ton steam capacity boiler is about 8~10KPa, while for 4 ton steam capacity boiler is about 18~20KPa.

What is the combustion mode of oil gas fired boiler?

The combustion mode of oil gas fired boiler is chamber combustion. Together with air, the powered fuel (solid fuel - coal dust), atomized fuel (liquid fuel - oil), and vaporized fuel (gas fuel - natural gas) is sprayed into furnace (combustion chamber) for suspension combustion.
