High temperature combustion is a common method for disposing of hazardous wastes that are not safe for landfill. If sufficient temperatures are reached, and maintained for an adequate residence time, hazardous organic compounds can be reduced to a mixture of inert ash, water vapour and carbon dioxide. The same is true for many industrial chemicals, although they may also have upper temperatures above which devolatilization reactions may release toxic heavy metal compounds. Ensuring that an incinerator reaches and maintains the correct temperature ranges over the complete mass of waste products is essential to safe disposal of the waste.

Using CFD Synergetics is able to simulate and assess the operations of a furnace before it is constructed reducing risk for our clients. In the example shown here, a range of furnace designs were simulated, enabling the client to implement the optimal design and successfully achieve their target temperatures.
