About Water Cum Smoke Tube Boiler
Gyantosh's Water-Cum-Smoke Tube Boilers combine the best of both classic boiler designs — the rapid steaming and high steam parameters of a water-tube boiler with the large water-holding capacity and steam-storage stability of a smoke-tube (fire-tube) boiler. The result is a boiler that holds steam pressure and dryness remarkably steady even when process steam demand fluctuates sharply.
In this hybrid arrangement, radiant heat is first absorbed in a water-tube furnace section, and the hot flue gases then pass through smoke tubes surrounded by a large water reservoir. That large water volume acts as a thermal buffer — absorbing sudden load swings and consistently delivering steam of around 98% dryness, ideal for processes sensitive to wet steam.
Every water-cum-smoke tube boiler is designed and manufactured in compliance with IBR 1950 and IS 2825 using certified boiler-quality pressure parts. The three-pass horizontal design maximises heat recovery, while automatic operation ensures dependable, low-attention running.
Available up to 25 TPH (25,000 kg/hr) and working pressures up to 28 kg/cm², GyanTosh water-cum-smoke tube boilers suit textile, dairy, chemical, paper, food-processing, and pharmaceutical plants with variable steam loads. Backed by over two decades of boiler engineering experience.

Water Cum Smoke Tube Boiler Specification
Fuels Used
Combustion & Heat Transfer
A water-tube furnace section absorbs intense radiant heat for rapid steaming and higher heat flux, giving the boiler its fast-response character.
Hot flue gases then travel through smoke tubes surrounded by a large water reservoir, recovering convective heat across multiple passes.
The generous water volume acts as a thermal buffer — storing energy and holding steam pressure and dryness steady during sudden load swings.
A three-pass horizontal layout maximises flue-gas residence time and heat recovery for high thermal efficiency.

Advantages of a Water Cum Smoke Tube Boiler
The large water reservoir buffers sudden changes in steam demand, holding pressure steady — a decisive advantage for batch and fluctuating-load processes.
Around 98% steam dryness protects downstream process equipment and improves heat transfer where dry steam is essential.
Combines the fast steaming and higher parameters of water-tube boilers with the storage stability and simplicity of smoke-tube boilers.
The three-pass gas path maximises heat extraction from flue gases, improving fuel economy.
Runs on a range of biomass and solid fuels, letting plants choose the most economical local fuel.
Robust boiler-quality construction and proven design deliver long service life and high availability under continuous operation.
