INNERGY has several types of models of combustion chambers in the market, each of these technologies being designed and adapted to the particular needs of each project.
Depending on the type of fuel, biomass or waste, the application of a different type of combustion system is recommended, which are currently: fixed grate, mobile grate, fluid bed and rotary kiln.
The rotary kiln is a system that is especially recommended for those processes that use complex fuels, thus being considered the fuels with a high content of aggressive elements such as chlorine and sulphur, among others.
The rotary kiln is the main part of the equipment where the combustion process of solid fuels, whether complex biomass or waste, takes place. This phase consists mainly of a metallic cylindrical body covered with high alumina refractory materials for maximum durability. This body is seated on a track which allows it to regulate its rotation for an optimal speed and time of permanence of the fuel in its interior. The proper sizing of its length and its rotation speed are essential for an effective combustion.
The rotary kiln is located just before the heat recovery body in the form of thermal oil, water or steam, to which all the heat generated by the biomass or waste yields. Generally, it is usually associated with post-combustion chambers to give the process gases more residence time.
When deciding what configuration the rotary kiln combustion system will have, it is essential to take into account some essential characteristics of the process such as: the characteristics of the biomass or waste, as well as the requirements of the process or the client.
Among the possible configurations would be:
CONSTRUCTION
Refractory material. Inclined rotation on two fixed heads
REGULAR, BALANCED MOVEMENT
