Rotary kiln - Import export

Rotary kiln incinerators are the workhorse of industry to burn solid waste in combination with sludge, waste gas and/or waste liquids and where the rotating motion transports the solid burning waste through the incinerator. Ashes are collected at the end of the rotating kiln and then combustion gases are completely oxidised in the static post combustion chamber. Rotary kiln incinerators typically feature different types of solid waste feeding systems for the bulky solid waste, containers and drums such as feeding screws and ram feeders. Waste gases and liquids are either injected into the rotary kiln, or the (vertical) post combustion chamber behind the rotary kiln. It provides for flexible and versatile incineration technology, but is characterised by a lower thermal efficiency with the associated higher operating and maintenance costs. Key Features Rotary kiln furnace with pre-set inclination and variable rotation speed. Labyrinth type seal with cooling and/or flushing with inert gas Different feeding systems for solid waste, waste liquids and waste gases Can be operated in a reducing or oxidizing environment Different drive mechanisms such as chain or direct drive, depending on the size of the kiln and the capacity Key Advantages - Robust and flexible design to burn a wide range of waste fractions – Proven technology – Destruction efficiency over 99.999% and less than 3% carbon in the ashes – Low NOx and CO emissions possible – Flue gas treatment train needed to meet acid, heavy metal, dust and PCDD/F emission levels

EUROPEM MultiFuel burners have a modular design to allow up to 15 waste gases and liquids to be co-combusted. The main burner body consists of a wind box with baffles. Two or three concentric central injection lances with injection nozzles are placed inside the air stream to inject the combustible liquids or gases. One or more rings with peripheral injection lances can be added for support fuel and/or to increase the number of waste gases that can be combusted. Low NOx emissions are achieved through staged combustion and a controlled flame temperature profile. Primary air is supplied through the burner wind box while secondary air is injected in the pre-combustion chamber. Axial MultiFuel Burner 1 to 20 MW capacity Long flame profile Suitable for rotary kiln and furnaces with long residence time Modular design Radial MultiFuel Burner The Radial MultiFuel Burners are equipped with a vortex control valve which enables manual control over the amount of turbulence and rotation that is given to the combustion air and the fuel/waste mixture. 1 to 20 MW capacity Control valve to control vortex and turbulence of the flame Shorter flame profile Suitable for standard fuels as well as combustion of waste gases and liquids Modular design Low CO emissions Low NOx emissions Robust design without moving parts for reliable operation Low maintenance requirements Most EUROPEM burners do not require a pre-combustion chamber or a secondary air injection chamber. This results in a shorter and hence more competitive overall combustion chamber design. Burner designs with pre-combustion chamber’s can also be furnished for specific applications.
