Kawasaki IF-J Gas-Fired Once-Through Boiler, 98% Efficiency (IF-4000JGE – IF-6000JGE)
Kawasaki IF-J once-through boiler, 98% efficiency version, natural gas, 4,000–6,000 kg/h equivalent evaporation, lighter than the 99% type.
Kawasaki Thermal Engineering (KTE) has built package boilers in Japan since 1899. Its multi-tube once-through boilers raise steam quickly, take little floor space and match the performance of larger water-tube and fire-tube boilers.
The 98% version of the IF-J series shares the boiler body and PID control of the 99% type with a lower dry weight (3,700–4,800 kg), a good fit where capital cost matters.
Key features
- 98% boiler efficiency, continuous PID combustion and feed water control
- Turn-down ratio 6:1 standard, 10:1 optional for IF-5000/IF-6000
- 0.98 MPa working pressure, 1.56 or 1.96 MPa optional
- Continuous PID control of combustion and feed water, steam pressure held within ±0.01 MPa (static load)
- Inverters on the forced draft fan and feed water pump as standard
- PID multi-unit control selects how many boilers run for the load
- Steam dryness of 99.5% or more from the centrifugal spiral-vane steam separator
- 15-year design life: feed water to the steam separator, built-in deaerator, all pressure parts annealed
- Colour touch-screen operation with colour status lighting
- Links to the Every FIT data logger (up to 16 boilers) and internet remote monitoring

FEYANA support in Vietnam
FEYANA supplies Kawasaki once-through boilers for projects in Vietnam: model and unit-count selection from your steam load, passing technical enquiries to the manufacturer, quotations, delivery follow-up and coordination of installation, commissioning and maintenance. FEYANA can also advise on feed water treatment so the boilers run reliably.
Information to send for a boiler proposal
- Maximum and normal working pressure (MPa)
- Maximum steam demand (kg/h) and feed water temperature (°C)
- Fuel type (NG, LPG, diesel), heating value and gas supply pressure
- Feed water quality and steam usage
- Annual operating hours and load fluctuation
- Site power supply (phase, voltage, frequency)
Data from the Kawasaki Thermal Engineering catalogue (CAT.No.EBI-0201), for reference only. Equivalent evaporation is based on feed water at 100 °C turned into steam at 100 °C; actual evaporation and efficiency are at 0.49 MPa steam pressure, 15 °C feed water and 35 °C room temperature.
