Industrial Waste Treatment Plants

TAKUMA’s industrial waste treatment plants help improve business viability and the global environment by incinerating a wide range of wastes and recovering heat in a highly efficient manner.

Since 1965, we have delivered more than 120 industrial waste treatment plants that are capable of incinerating a wide range of wastes, including miscellaneous plant waste, waste plastic, and infectious medical waste. In recent years, we have also been supplying plants which realize high-efficiency heat recovery by installing waste heat boilers, steam turbines and generators. These plants make it possible to increase profitability by reducing interrnal power consumption and by selling power to the grid, as well as to help revitalize regional industry by supplying heat to off-site facilities.

Product Line-up

Rotary kilns and stoker furnaces
Rotary kilns and stoker furnaces
This combination of combustion methods is ideal for fluid sludge and powders as well as oil sludge and waste plastic that are conducive to gasification combustion.

Rotary kilns and stoker furnaces (multi-type)

Advantages

1
Stable combustion of a wide range of wastes
Miscellaneous waste such as wood and paper waste are burned in the stoker furnace, while wastes with a high level of fluidity or viscosity, for example waste plastic, oil sludge, waste liquid, and sludge, are simultaneously incinerated in the rotary kiln.
2
Reduced clinker formation
Clinker formation is reduced by burning out the waste in the stoker furnace after it has passed swiftly through the rotary kiln.
3
High durability and prevention of blockages
These systems incorporate large intakes and outlets and can eject waste even when it’s mixed with foreign material such as metal. Long-term operation and lower maintenance costs are realized due to high durability.

Advantages

1
Stable combustion of a wide range of wastes
Thanks to a design that takes into account incineration of high-calorie wastes and bottom ash, our step grate stoker furnaces can incinerate a wide range of wastes and allow not only wood and paper waste but also mixed combustion along with waste plastic or dedicated combustion of paper sludge.
2
Reduction in unburned material fall-through
Air is injected through vertical gaps in the fire grate to reduce the amount of unburned material that falls through. These systems can also accommodate plastic that melts as it burns and powdered dried sludge.
3
High durability and prevention of blockages
These systems incorporate large intakes and outlets and can eject waste even when it’s mixed with foreign material such as metal. Long-term operation and lower maintenance costs are realized due to high durability.
4
High-temperature combustion
Our step grate stoker furnaces use fire grates made of heat-resistant cast steel to enable high-temperature combustion, helping reduce unburned ash. In addition, by adopting a water-cooled stoker of which grates' durability is even higher, replacement frequency can be significantly reduced .
5
Low-NOx operation and clinker prevention
Flue gas can be recirculated. Controlled combustion allows low-NOx operation while preventing clinker formation on side walls.
