HI3: APCS patented hybrid insertion technology (HI3) provides state-of-the-art technology to effectively introduce various compounds into the heart of the furnace environment. Compounds have been devised by numerous third-party firms. These compounds improve bottom line performance for the power plant by reducing slag accumulation and maintenance cost. Thermal efficiency of the furnace is improved thereby improving production cost. Also these compounds have an improvement in the volume of pollutants. APCS's method of injection of these compounds is far more efficient than other alternatives and can be implemented quickly and at low cost.
