DEWaste incineration
Incinerator
To ensure that the waste burns completely, temperatures in excess of +1000 °C must be reached. This is accom-plished by blowing in large quantities of air, primary air from below and secondary air from above. Air quantity and air pressure must be precisely measured. Moreover, a defined waste layer thickness of approx. 50 cm on the combustion grate is required to ensure even burning. State-of-the-art measurement technology makes automated, economic operation possible here.
Layer thickness measurement with VEGAPULS 68
The waste layer thickness on the grate is measured continuously with the radar sensor VEGAPULS 68. The sensor measures right through the hot burning gases and flames that can be in excess of +1000 °C. Focused antenna signals enable very precise measurement and control of the charging process.
Air measurement with VEGADIF 65 and VEGABAR 52
Air quantity, i.e. air flow, is measured in the respective supply tube with a VEGADIF 65. This is done by passing the air through a Venturi section, generating a differential pressure of a few millibars, and the flow is calculated by precise measurement of the pressure difference. In addition, the air absolute pressure in the supply tube is measured with a VEGABAR 52 pressure transmitter.
