Fire Tube Industrial Steam Generator Natural Circulation Low Pressure
I. The unique features of central heating boiler
1. It adopts wet back & 3-pass structure which ensures boiler safe operation and extend service life.
2. Boiler equips European Burner, fuel combustion can achieve automatic adjustment to save energy,
also decrease the dust emission & SO2 emission & NOx emission.
3. Boiler equips Energy Saver which can improve boiler thermal efficiency more than 2-3% &
decrease the temperature of exhaust smoke.
4. It’s suitable for Natural gas & LPG, diesel & light oil & heavy oil ...
II. Why are you choice our central heating boiler?
1. Lower dust emission & SO2 emission & NOx emission,
dust emission concentration < 50mg/m³
SO2 & NOx emission concentration < 100mg/m³
2. Boiler equips European Burner, fuel combustion can achieve automatic adjustment.
3. We supply 2 units Water Pump (one duty one standby) which from the famous pump manufacturer.
4. Boiler can achieve automatic temperature control & pressure control & feed water control & feed fuel control & safety indication ...
We also freely supply you a set of inner parts of Electric controller for standby.
5. Boiler with stainless cladding, anti-corrosion & anti-rust & beautiful appearance.
6. Comprehensive after-sales service.
We can design layout drawings of boiler system according to your actual requirement.
Also can dispatch engineer to guide installation & commissioning.
