Boiler characteristics
Advanced three pass wet back design:adopts the most sophisticated
three returns all wet back structure,thread smoke tube structure,
weld joint with high quality.
Advanced manufacturing equipment endows Safe and reliable
property:adopts corrugated furnace lamps, multi-chain protection.
Water level, steam pressure, gas pressure protection. And before
leaving factory, all the boiler have been rigorous inspection and
testing, including pressure tests and X-ray detection.
Large boiler proper heating area:adopts unique design of a large
combustion chamber which increases the radiation heating furnace
area, reducing the size of the boiler, reducing the NOX emissions.
High efficiency 98%:with threaded pipe and high effective
insulation materials and econoizer, increasing the heat transfer
and improve boiler thermal efficiency.
PLC intelligent controller:boiler control system suitable for high
temperature, high humidity environment of long-term operation.
High standard: strictly in accordance with Chinese national norms
and standards of production, all boiler pressure parts are of high
quality steel.

FAQ
1. What are the available fuel for the oil gas fired boiler?
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.
2. Whether the boiler can burn dual fuel or multi-fuel?
boiler have oil burner, gas burner, and oil&gas dual fuel
burner, we can offer the specific burner based on customers’
requirement.
3. 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.
4. 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.
5.The brand of burner?
The brands of burner are Italy Baltur, Rellio, Elco, etc.
