IF Series – Dual Fuel Fired

Package Boiler - Dual fuel fired

Stable steam pressure, high steam dryness, long life (designed for 15 years), simple operation and wide turn-down.


Nowadays, with our Multi tube Once-Through boiler, comparing to conventional fire tube and water tube boiler, it has many clear benefits to our client who needs considerable amount of steam for heating process.  One of them is its boiler efficiency of up to 98% with gas firing, the higher the boiler efficiency, the less the fuel is burnt for the same amount of steam output, this helps our client to achieve a very attractive fuel cost saving.  Secondly, its quick start up in 15 minutes (cold start) also contributes to fuel cost saving, compared to fire tube boiler which normally requires around 40 minutes to even 1 hour for cold start.
