Expected Results

The main expected result are the following:

Preliminary  characterization:

  • Report combustion emissions and energy consumption of the main furnaces present in the European market
  • mass and thermal balance of the furnace focused on the voices connected to waste gases and preheated air.
  • fluid dynamic model able to simulate the behaviour of the furnace in different operating conditions exploring the WG and air flow modifications and their impact on combustion and heat exchange

Combustion optimization:

  • Validated Combustion Optimization System trialed on 2 two different existing furnaces
  • Noreduction of 30-50 % and energy savings of 5-6 % in trial with small regenerator, 1-2 % in trial with medium-big regenerator

Port exhausted gas recycling system:

  • Validated Port Exhausted Gas Recycling System trialed in a new furnace
  • Noreduction of 25-30 % and energy savings of 3 % with respect to newest ‘staging’ technology proposed in the BAT.

Monitoring improvement:

  • Validated automatic tool of temperature measurements and distribution based on thermography and Validated automatic tool of COand CO flame distribution. Both will improve design and performance of modern glass furnaces and allow continuous monitoring of the process useful for system control or diagnostic analysis.
  • Proven efficacy of infrared thermography applied to the glass furnace system as innovate approach for temperature monitoring and combustion diagnostic. The device will be installed in the combustion chamber. The proposed approach will be tuned to measure the temperature distribution on the liquid glass in order to have a continuous process monitoring.
  • lncreased awareness and knowledge amongst stakeholders and target groups on the possibility to reduce emission of Noand consumption of energy by two different innovative systems.

Direct environmental results achieved

During operation of the pilot plants with pull rate of about 200 ton/day, 12 months at least for the furnace with new port design and 18 months for the two furnaces with combustion optimization, progressively achieving targets during trials, the following environmental results are expected to be achieved:

  • total reduction of Noemissions of 178 Ton
  • total reduction of energy consumption of 1021 Tep
  • total reduction of COemissions of 2117 Ton.
