From this study, an average emission factor for PCDD/F of 1020 ng / kg of wood burned (range: 552– 1410 ng / kg ), and an average emission factor for I-TEQ of 17.1 ng / kg of wood burned (range: 7.34– 22.8 ng / kg ) were estimated.Read More
1/6/2018 · Based on a study conducted by Spirax Sarco, it is shown that if an economiser is used for a boiler system, it can increase the efficiency by 1% for every 5 C reduction of flue gas temperature. This indicates that the fuel consumption of the system can be reduced by 5–10% with a payback period of less than 2 years  .Read More
