High Efficiency Fire Tube Gas Diesel Oil Fuel Fired Condensing
Steam Boiler for food factory
The exhaust gas temperature of normal three pass fire tube boiler
is high, the water vapor is in the overheated or gaseous state. If
the exhaust temperature is reduced to a sufficiently low level, the
water vapor in the flue gas will condense and the latent heat of
vaporization of the condensate can be used.
The boiler which takes advantage of the water vapor in condensed
flue gas,fully absorbs the exhaust heat of the boiler and the
latent heat of vaporization of the steam is called a condensing

Except the features of normal three pass fire tube steam boiler,
our condensing steam boiler has the following advantages:
1.High effiency(exceed 92%) and energy saving(save gas 3-5m3/h;save
(1).Three pass structure,which extend the flow of smoke and enhance
the heat transfer.
(2).Adopt bog size whole corrugated furnace,big heating
area,sastify the free expansion of boiler, improve the boiler
(3).Whole adopt corrugated tubes,strengthening heat transfer and
eliminating welding stress. Other companies also use corrugated
tubes, but we adopt the latest professor “Li Zhiguang”(a very
famous boiler expert in China)technoly,the depth of the screw
thread and spacing between two screw threads are rationally
2.Enough steam output and high quality steam.
(1). Our boiler design big size water volume,the steam output is
stable and steam quality is good.
(2).Design special steam water separator,reduce steam humidity and
improve steam quality.
3.Safe and reliable.
(1).Whole wet back structure and transition multi-loop
full-temperature condenser design, ND just material, fin tube
design,which highly reduces the back plate sheet temperature(around
(2).Double layer 12cm aluminum silicate insulation material,two
stage anti-leak design and tight seal to avoid leakage phenomenon.
(3).Design tension bars,increasing the tube plate strength,
(4).Explosion proof door design,prevent explosion, reduce the
damage to the boiler, improve the safety of boiler.
(5).Two water level gauges and two Spring Safety Valve, Backup
protection, safe and reliable.
4.Long life span(More than 20 years ).
(1).5-10% overload capacity design and reasonally configurate spare
parts,reduce equipment fatigue.
(2).New type refractory material,solidification strong, long using
life,which will not fall off after shaking.
(3).smoke chamber ultrasonic testing, overpressure 40-50% water
pressure test,ensure the boiler quality.
(4).Raw materials are provided by China famous steel and steel pipe
factory provide, which controls the boiler quality from source.
(5).61 years boiler manufacturing experience, mature design and
5.Intelligent and fully automatic.
(1).Adopt world famous brand burner,including baltur, riello from
italy, weishaupt,hofat from Germany,Olin from Finland, etc.
(2).Adopt mechanical-electrical integration control equipment and
programmable logic controller(PLC) touch screen electric control
(3).Continuous feeding water vertical multistage centrifugal
stainless steel pump,no need manual adjustment and at same time,
ensure the stable&safty running of boiler.
(4).Flow type intelligent water treatment equipment,automatic restore
and microcomputer operation.
6. Easy inspection and maintenance.
(1).Double door design , detachable front flue box and rear flue
box, and manholes and hand holes.
(2).Integrated wiring device, so that wire-controlled connection is
more convenient and easier for maintenance.After installation, the
boiler looks beautiful.

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’
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.
