Energy saving and pollution abatement in glass-melting furnaces, cement kiln and baking ovens

Cel

To develop and validate a computer simulation model which can be used for a variety of furnaces, kilns and ovens. Such a code will be used to explore oven concepts and control strategies which can lead to energy savings and pollution abatement. Experimental work aiming at the evaluation of the model will include testing of sensors suitable for harsh environments.

The computer model for a gas- or oil-fired glass-melting furnace, developed in a past EC contract (EN3E-0153-P), will be improved and extended to include other fuels (e.g. coal) and other types of furnaces, kilns and ovens applications; environmental aspects such as NOx emissions will also be incorporated (ICSTM and IST). The model will be validated with experimental data from a laboratory furnace installed at ICSTM, applied and adapted to simulate glass-making furnaces, cement kilns and baking ovens. The active participation of industry (glass, cement and agro-industry) promises a good penetration of this tool (the code) in the sector.

For the experiments, a variety of sensors will be used. To provide temperature distributions along walls of furnaces, kilns and ovens, temperature sensors operating in high-temperature environments will be selected and eventually adapted by LSTM- Erlangen; in addition infrared wall temperature sensors will be developed. For the measurement of quantities of coal and air supply to the burner, a Coriolis mass flow meter and flow rate regulator will be developed (LSTM-Erlangen). Development of sensors and monitoring systems for gas temperature, pollutants and moisture content will be carried out by TNO.

Modelling (CRES, IST) and experimental work (INTERG, TNO) on electric and gas-fired baking ovens (e.g. bread) will include development of a multi-sensor system for water vapour partial pressure, level of forced air circulation and crust colour.

The general code will also be applied and adapted to cement kilns; work will include the integration of a NOx emission model (IST); and modelling of the major chemical reactions (INTERG, CRES); validation of the models will be done against data obtained from the TITAN kilns (CRES).

The model will be extended to simulate different parts of a glass- making furnace; the near burner region (IST); the control system (University of Mons, ADERSA); the fore-hearth of the furnace (ULB).

An extension of the project focusses on :

Characterization of the near burner region in glass-melting furnaces and cement kilns.
Development of potentiometric sensors for temperature, heat flux and NOx measurements.
Development of control strategies for the design of an industrial control loop of a glass-melting furnace.

It is estimated that the energy savings possible by the application of the results of this project are as follows: glass furnaces (5-21 %) ; cement kilns (3-10 %) ; baking ovens (15-40 %).

The possible NOx abatements are :

glass furnaces (up to 60 %) ; cement kilns (up to 30 %).
