About Travelling Grate Boiler
Gyantosh's Travelling Grate Boilers are biomass-fired steam boilers built around a continuous moving grate — an endless chain of grate bars that carries fuel steadily from the feed end, through the combustion zone, to controlled ash discharge at the far end. It is one of the most proven and sustainable technologies for firing biomass, typically delivering thermal efficiency 3–4% higher than comparable grate systems.
Fuel is spread evenly across the grate and burns progressively as it travels, giving consistent bed depth, stable combustion, and excellent burnout. The steady mechanical movement removes the need for manual stoking, keeps the fuel bed uniform, and enables reliable continuous operation at high capacities.
Every travelling grate boiler is designed and manufactured in compliance with IBR 1950 and IS 2825 using certified boiler-quality pressure parts, durable grate chains and bars, and robust refractory. Water-tube, single-drum, bi-drum, and hybrid configurations are offered to match required steam parameters and duty cycle.
Available in capacities up to 275 TPH and pressures up to 130 kg/cm², GyanTosh travelling grate boilers are ideal for captive power, sugar mills, paper mills, food, chemical, and textile plants running on biomass. Backed by over two decades of boiler engineering experience.

Travelling Grate Boiler Specification
Fuels Used
Combustion Technology
An endless chain of grate bars carries fuel steadily through the furnace, ensuring uniform bed depth, stable combustion, and automatic ash discharge.
Fuel spreaders distribute biomass evenly across the grate width, giving consistent combustion and minimising unburnt carbon losses.
Grate speed (typically 0.5–2 m/min) is tuned to fuel type and boiler load, matching residence time to complete burnout requirements.
Under-grate air zones supply the right amount of air along the grate length to optimise drying, ignition, combustion, and burnout.
Freeboard secondary air completes combustion of volatiles above the bed, improving efficiency and reducing emissions.

Advantages of a Travelling Grate Boiler
Travelling grate firing typically achieves 3–4% higher thermal efficiency than other grate technologies, reducing fuel cost over the plant life.
A carbon-neutral, renewable route to steam and power using bagasse, wood chips, and agricultural residues.
Configurations up to 275 TPH suit the largest captive power and cogeneration duties.
Continuous mechanical fuel movement removes manual stoking, keeps the bed uniform, and enables reliable 24×7 base-load operation.
Even fuel spreading, adjustable grate speed, and zoned air deliver excellent burnout and low unburnt carbon in ash.
A mature, well-understood technology with durable grate chains and straightforward maintenance for high availability.
