The fuel feed system is comprised of all those elements necessary to deliver fuel to the point of consumption, in this case the combustion/gasification chamber. This is one of the most critically mportant tasks performed by HBC's systems. HBC's advanced and reliable systems incorporate fuel feed units that offer the greatest reduction of uncontrolled air being introduced into the system thereby increasing gasification/combustion efficiencies to a nominal level. The following narrative begins at the Metering bin. The typical conveyance from the storage area to a metering bin is accomplished through the use of a reciprocating/walking floor. For a detailed description see "Reciprocating/Walking Floor".
