The presented paper introduces a simple systematic method for a fuel saving evaluation achieved by Energy Retrofit of Thermal Waste Processing Unit. Waste thermal treatment and its energy recovery represent a promising energy source, while enabling the ecological waste abatement. However, the waste thermal decomposition is generally an energy intensive process associated with significant external fuel demand. The significant fuel savings could be achieved by the existing unit retrofit in order to improve a waste heat utilization to preheat (or dry) the processed waste. The fuel (and operational) savings achieved by this so-called Energy Retrofit are however associated with high investment costs, which leads to trade-off between achievable fuel and financial savings and investments. To perform the trade-off correctly, the fuel saving evaluation is essential. The developed method enables quick and accurate fuel saving calculation, which does not necessitates using of any professional software or intensive calculation procedures. The method is further applied on model case study of the unit processing waste gas containing Volatile Organic Compounds.
