Frequently Asked Questions
How much wood does the boiler consume per hour?
A 1 Ton (1000 Kg/hr) boiler typically consumes approximately 250 to 300 Kg of wood per hour, depending on the calorific value and moisture level of the wood.
Can I use other fuels like coal or briquettes in this boiler?
Yes, our wood-fired boilers feature a versatile grate design that allows you to switch to coal or biomass briquettes if wood supply is limited.
What is the thermal efficiency of this wood-fired model?
Our wood-fired boilers achieve a thermal efficiency of approx. 70% to 75%, which can be further enhanced by installing a heat recovery unit (Economizer).
How does wood-firing compare to diesel in terms of cost?
Wood is significantly more economical than diesel or gas. Switching to wood can reduce your steam generation costs by up to 50% to 60%.
What is the steam output capacity?
The rated capacity is 1000 Kg/hr (1.0 TPH) of steam from and at 100°C.
What working pressures are available?
Standard working pressures are 10.54 Kg/cm² and 17.5 Kg/cm². We can also provide custom designs for higher pressures.
Is this boiler IBR or Non-IBR?
We manufacture both IBR (Indian Boiler Regulations) and Non-IBR versions. For a 1 Ton capacity, an IBR certified unit is generally recommended for industrial safety compliance.
What is a "Horizontal Multitubular" design?
This means the fire passes through multiple tubes surrounded by water. It provides a larger heating surface area, ensuring faster steam generation compared to traditional vertical boilers.
Does the boiler require electricity to operate?
Yes, a small amount of electricity is required to power the feedwater pump and the Forced Draft (FD) fan used for combustion air.
How is the fuel fed into the boiler?
The standard 1 Ton wood boiler is manually fired through a large fire door designed for easy loading of long wood logs.
How often do I need to remove ash?
Ash should be removed from the bottom ash pit once or twice per shift (every 4–8 hours) to ensure proper airflow through the grates.
Is it difficult to clean the tubes?
Not at all. Our boilers feature hinged front and rear doors, allowing easy access to the smoke tubes for periodic cleaning and soot removal.
How long does it take to start the boiler from cold?
A wood-fired shell-type boiler typically takes 45 to 60 minutes to reach full operating pressure from a cold start.
What safety valves are included?
The boiler comes with two IBR-approved safety valves, a water level indicator, a pressure gauge, and a fusible plug that melts to prevent overheating if the water level drops too low.
What kind of foundation/civil work is required?
Since the 1 Ton unit is relatively heavy, it requires a stable PCC (Plain Cement Concrete) foundation. We provide the detailed foundation drawing upon order.
Does this boiler require a pollution control system?
Yes, to comply with GPCB/Pollution Board norms, we recommend installing a Multi-Cyclone Dust Collector to trap fly ash and soot before the smoke enters the chimney.
What height of chimney is required?
As per standard norms, a 1 Ton wood-fired boiler usually requires a 30-meter high chimney to ensure proper natural draft and local environmental compliance.
Can the boiler be installed outdoors?
While the boiler is robust, we recommend a simple shed (Boiler House) to protect the accessories, electrical panel, and insulation from rain and direct sunlight.
Does Indian Boilers provide installation support?
Yes, our Ahmedabad-based team provides complete installation, commissioning, and on-site training for your operators to ensure safe and efficient firing.
