Inova Grate

The new Inova Grate is a reciprocating grate with physically separated grate zones and individual reciprocating grate elements. The grate is built to be inclined at a lower angle, allowing a lower and more compact design and reducing the space required. At the same time larger grate blocks enable the subsequent costs of operation to be reduced. The size of the grate and the appropriate cooling system (water or air) are determined on the basis of the combustion diagram and the specific requirements of the plant and the waste processed.

Kanadevia Inova R-Series Grate

The R-Series incinerator grate developed in-house by Kanadevia Inova is a reciprocating grate inclined at an angle of 18° with individually movable grate elements. This feature enables operational flexibility and ensures that the waste is transported, mixed and combusted efficiently. The R-series grate is air-cooled as standard. The size of the grate is determined on the basis of the requirements specific to the plant and the waste it treats.

Grate Cooling

All our grates can be built with water or air cooling, with the choice depending on the combustion diagram and the specific requirements of the plant and the waste processed. Air cooling makes sense if the calorific value of the waste is low to average. Here the primary air is also used to cool the grate. For waste with a higher calorific value a water-cooled grate makes more sense. By decoupling grate cooling from the air supply, the air supply also enhances the combustion process, resulting in better quality bottom ash and less flue gas.

Low Excess Air Process (LEAP)

Our staged combustion process consists of two injection stages for secondary air and recirculated flue gas. LEAP reduces the combustion air flow rate in your installation, enabling the use of smaller components for the boiler and flue gas treatment system. Even distribution of corrosive agents thanks to intense mixing also reduces the risk that the boiler will corrode, even at lower oxygen levels.

Kanadevia Inova RingJet

The ringjet stage is a very typical component of wet scrubbing. Placed in the scrubber, Kanadevia Inova RingJets produce a mist of water that separates fine particulates and aerosols from the exhaust air or flue gases. Laden with pollutants, the droplets are then removed. The Kanadevia Inova RingJet is easy to fit, robust and to a large extent maintenance-free. It is space-saving, and can also be retrofitted to existing scrubbing towers.

Residue Handling & Treatment

Kanadevia Inova DryMining

Kanadevia Inova DryMining is a fully automatic treatment process for recovering ferrous and nonferrous metals from bottom ash and the boiler ash. The tower installation can be used with wet or dry fine bottom ash discharge. The first step is to separate out the ferrous metals, before the nonferrous metals are sieved out and sorted by density. The process is controlled either from the control tower or with the help of a local switchboard.

Control Systems

Combustion Control System Autaro^TM

Autaro^TM  combustion management system that doesn’t only produce steam on a stable basis.​

The main job of a combustion control system is to ensure even plant operation and the constant production of steam. Another key factor is flexibility. Fluctuations in waste compositions and calorific values at different plants require correspondingly flexible processes – and thus the right control system. This is also important if the waste does not burn as desired. In such a case it must be dried and moved, and oxygen must be fed in additionally.
