The centrepiece of every system is, of course, the combustion chamber with its grate and combustion philosophy.
All parameters of the combustible material must be taken into account, as well as the question of sustainability in dealing with the waste.
Incinerators should have a safe charging system, in this case a two-chamber ceiling charging system consisting of a manual or automatic chamber opening and a driven slide or flap system to safely seal off the combustion chamber.
Picture above: Burner test
Two or more burner systems should be used to heat up the system and support the firing at low calorific values of the waste.
In any case, one burner system for the main combustion chamber and one burner system for the post-combustion chamber.
The combustion chamber temperature should be 850 - 950 °C in the main combustion chamber and 950 - 1150 °C in the post-combustion chambers and the combustion temperatures should be controlled automatically.
An emergency system (pressure and temperature-dependent) must be provided, depending on the size of the system.
Combustion grate
Good ventilation of the main chamber is the basis for clean and complete incineration of the waste on an incineration grate.
This new type of ZANNI combustion grate is easy to maintain and inexpensive to manufacture and maintain.
Incineration grates are wearing parts. It is suitable for all types of waste, such as clinical waste, contaminated materials, other solid and sludgy waste, such as sewage sludge.
In this system, mechanical components have been completely dispensed with and replaced by combustion air.
Ventilation of the combustion chambers
Ventilation is provided by one or more combustion air blowers, the control of which is regulated by appropriate oxygen measurements to ensure sufficient oxygen enrichment and thus complete combustion.
The systems are usually fitted with sight glasses in the combustion chamber as well as numerous connections and connection options for necessary and additional measuring devices.
Ashes are usually removed either manually via ash removal doors or via automatic ash removal systems.
