DEEnergy production from waste
Feed system for waste incineration
In the waste incineration process, a defined quantity of waste material is transported through the furnace on a combustion grate. To ensure that the waste is completely burned, a temperature of +1000 °C must be reached and a defined quantity of air supplied to the combustion chamber. The air quantity and the air pressure must be measured exactly to regulate the furnace.
Flow metering of combustion air with VEGADIF 65
The Venturi section of the main air tube is a defined constriction in which the pressure decreases by a few millibars. A VEGADIF 65 with small measuring range measures this pressure drop with high accuracy and calculates the air flow quantity from it.
Pressure measurement of combustion air with VEGABAR 52
A slight underpressure is continuously maintained in the furnace so that sufficient air is sucked in for the combustion process. This is controlled by measuring the air pressure in the respective main air tube with a VEGABAR 52 pressure transmitter. Pressures between 25 and 60 mbar are measured here.
