Frequently Asked Questions
What constitutes "High Pressure" for this specific model?
While standard boilers operate at 7–10 Kg/cm2, our high-pressure series is designed for 10.54 Kg/cm2 to 21 Kg/cm2 to meet specialized industrial needs.
How fast can this boiler reach its maximum operating pressure?
Depending on the design (Shell vs. Coil), it typically reaches full pressure in 15 to 25 minutes from a cold start.
What is the thermal efficiency of the 750 Kg/hr model?
The base efficiency is 88% to 90%, which can be enhanced to 95% with an Indian Boilers' high-efficiency economizer.
Does it produce "Dry" steam?
Yes. It features a large steam disengagement space and internal moisture separators to ensure high-quality, dry saturated steam.
Which fuels are compatible with this 750 Kg boiler?
This unit is a multi-fuel system compatible with Diesel (HSD), LDO, PNG, and LPG.
What is the fuel consumption at full load?
Approximate consumption is 48–52 Liters/hr for Diesel or 52–56 NM3/hr for PNG, depending on feedwater temperature.
Can I install a dual-fuel burner on this model?
Yes. We can equip the unit with a burner that switches between gas and oil, providing flexibility during fuel price fluctuations.
How does the "3-Pass Wet Back" design improve fuel savings?
It ensures that heat stays in the water longer and eliminates the need for a rear refractory, reducing heat loss and maintenance costs.
What is the power consumption for the 750 Kg/hr boiler?
The total connected electrical load (burner + feed pump) is approximately 5 HP to 7.5 HP.
Is this boiler IBR certified?
Yes. Every 750 Kg/hr high-pressure unit is manufactured strictly under IBR (Indian Boiler Regulations) guidelines.
What safety interlocks are provided?
It includes dual IBR safety valves, a low-water level alarm with burner lockout, and a high-steam pressure cut-off switch.
What material is used for the pressure parts?
We use ASTM/SA 515/516 Gr. 70 boiler-quality plates and IBR-certified seamless carbon steel tubes.
How often should IBR inspections be conducted?
As per law, an annual inspection by the local Boiler Inspector is required to renew the operating certificate.
What is the "Hydraulic Test" pressure for this unit?
The boiler is hydraulically tested at 1.5 times its design pressure to ensure structural integrity.
Is this model available as a skid-mounted unit?
Yes. We provide a skid-mounted "Plug-and-Play" package where the boiler, pump, and panel are pre-aligned for fast installation.
What are the water quality requirements?
To prevent scaling at high pressure, feedwater must be treated via a Water Softener to keep hardness below 5 ppm.
What is the footprint (size) of the 750 Kg/hr boiler?
It is a horizontal shell-type unit, typically requiring an area of approximately 10ft x 6ft, excluding the chimney and water tank.
Does it require a tall chimney?
Yes. Depending on local pollution norms, a 30-meter chimney is usually required for proper emission dispersion.
Do you provide maintenance support in Ahmedabad?
Yes, our Ahmedabad-based headquarters offers 24/7 service, genuine spares, and Annual Maintenance Contracts (AMC).





















Dhaval Kamdar –
5 stars for the 750 kg/hr series! We’ve seen a noticeable drop in fuel consumption thanks to the three-pass wet-back design. The thermal efficiency is consistently around 88-90%, and the PLC-based control panel makes monitoring the system very straightforward. It’s a robust piece of engineering that has become the backbone of our production line. Great value for the investment.
