Waste heat recovery in glass production now successful

OPTIMUM has successfully installed our low fouling OPTIMUM boilers with patented APCS in-line cleaning system in the glass industry. The OPTIMUM waste heat recovery systems are applied in  combination with regenerative and oxyfuel furnaces in both container an flat glas applications and have proven to be robust and reliable ensuring a stable furnace operation.

Feasibility study for container glass industry

In 2010, the TNO Glass Group, OPTIMUM and a major container glass manufacturer carried out a system evaluation and economictechnical feasibility study for the application of the OPTIMUM steam driven cullet preheating concept for one of their furnaces.As an integral part, a system evaluation was also carried out for a typical 320 MT/day gas and 320 MT/day oxy fuel fired furnace to show the potential energy savings and cost savings. The furnace performance evaluation (energy consumption, flue gas flows, heat losses) with and without cullet preheating as well as setting up typical realistic cases is based on TNO’s extensive energy balance modeling capabilities and experiences

Cullet preheating using steam generated by flue gas

TNO reference project for the glass industry

As a service for the industry, TNO has investigated whether a new combination of proven technology can be applied in order to save energy, reduce production costs and decrease waist gas emissions. About 30 % of the energy input is lost by the heat of the exhausted flue gas. Generating steam by flue gas heat, and using this steam to pre-heat culet, will lead to energy savings between 8%- 12,5%.
