Cashew Shell Burner
Turn shell waste into heat
A cashew shell burner that combusts shell waste to generate the heat that drives steaming and drying — cutting fuel cost and shell disposal at once.
The TTQ Cashew Shell Burner combusts cashew shell — the plant’s main waste stream — to generate hot air or water for the steaming and drying stages. It turns a disposal problem into free process heat, sharply cutting fuel cost and enabling near-fuel-free operation. It pairs with the dryer, steamer and boiler, and underpins the carbon-credit and biomass-energy story of a modern cashew plant.

Turning the waste stream into the fuel bill
Shell combustion
Burns the plant’s own shell waste cleanly for process heat.
Near-free heat
Makes steaming and drying largely fuel-free, cutting energy cost.
Feeds the line
Supplies hot air or water to the dryer, steamer and boiler.
Waste to value
Turns a disposal problem into an energy and carbon-credit asset.

The same TTQ boiler range fires cashew shell, wood chips or pellets — 300 to 4,000 kg of steam per hour. What changes between the three is the fuel handling and the burn characteristics, not the boiler you order. If you shell your own nuts, shell is the fuel that costs nothing; see the wood chip boiler page for the biomass comparison.
Efficiency of controlled combustion ranges between 90–95%, which is what lets a plant meet its own steam demand from its own shell. Controlled combustion is also what keeps maintenance and cleaning intervals long: incomplete burn deposits tar and unburned CNSL residue on heat-exchange surfaces, and those deposits both insulate the tubes and shorten the run between cleandowns.
The process, drawn
The shell energy loop
The cleanest economics on the site: the waste stream from stage 03 comes back as the heat for stages 02 and 04.
The same TTQ boiler range fires cashew shell, wood chips or pellets. Note the dryer is heated by electrical coils or by boiler steam through heat-transfer coils — the shell burner fires the boiler and the roasting machine, not the dryer directly.
One boiler range, three fuels
The same TTQ boiler fires cashew shell, wood chips or pellets. Which one you burn is a supply question, not an equipment question.
Shell combustion efficiency runs 90–95%. Multi-fuel flexibility costs roughly 20–30% more than a single-fuel boiler, which is worth it only if your shell supply is genuinely uncertain.
Where it fits in the process
The energy heart of the plant — it burns shell waste to heat the steamer and dryer, closing the loop on the plant’s own by-product.

Carbon Credits in the Cashew Industry
By burning cashew shell as biomass instead of fossil fuel, a cashew plant can cut emissions and potentially earn carbon credits — turning waste-to-energy into extra revenue.
