McON Air zur Luftmengenmessung in der Müllverbrennungsanlage Bonn

deckblatt-reference-bonn-300x352-2

Einleitung

(dt.) Der Einsatz von PROMECONs innovativer Messtechnik McON Air in der Luftmengen-Regelung in einer Müllverbrennungsanlage führt zu Reduktionen der Temperaturspreizung oberhalb des Rostes um fast 50% und damit zu einer deutlich optimierte Prozessführung.

Erfolgreiche Innbetriebsetzung in der MVA Bonn

Die Müllverwertungsanlage der Stadtwerke Bonn GmbH (SWB-Verwertung) wurde 1992 mit zwei Linien als thermische Verwertungsanlage in Betrieb genommen. Seit 2000 wird die Anlage mit drei Linien und einem Jahresdurchsatz von ca. 250.000 Tonnen Brennstoff betrieben.

Mit der erfolgreichen Inbetriebsetzung der innovativen Luftmesstechnik McON Air der PROMECON GmbH, welche die individuelle Regelung der Rost-Primärluft der Linie 3 der MVA Bonn unterstützt, ist eine deutliche und wegweisende Innovation für die Feuerführung an einer Müllverbrennungsanlage ausgeführt worden.

Peak Performance - latest technology for optimised operation of large scale mills

300x352

Introduction

The article describes the task of accurately measuring gas flow through a large pulverizer such as a raw mill. Besides the pure mechanical layout of a pulverizer special attention has been given in recent years on the material and gas flow management through a large scale mill. The main aspects for this motivation are the product quality itself but beyond that also the flat lined operation of the pulverizer.

Optimised Grinding

The largest concern with grinding certainly is the quality of the processed product i.e. its fineness distribution as well as the nominal maximum throughput of a pulverizer at which it can keep the guaranteed fineness values.

A mill has three basic processes which act together in order to achieve the final grinding result:

The mechanical grinding part: This process is connected to the grinding elements of the mill, the tires, the bowl (on a vertical spindle mill) or the grinding media in a tube mill. Especially in a vertical spindle mill the roller pressure will not only have an impact on the fineness of material in conjunction with classifier speed but also ...

Go with the Flow - efficient gas flow measurement in cement plants

Introduction

For the proper operation of equipment in a cement plant, knowing the flow rate is essential. In the past, high temperature and particulate in the gas stream have prevented online gas flow measurement. But the Promecon Air Flow System utilises the particulate to measure the velocity of the gas stream.

Measurement technology

The system utilises the triboelectric principle. Electrical signals created by (dust) particle clouds passing each of the upstream/downstream sensors are cross correlated and referenced by their time shift. The digital system requires no calibration, ...
