ABSTRACT:
This invention relates to a method to provide a system for solid material arging into vertical reactors by electronic control of the exhaust gases, a unique process applied for charging into vertical reactors, cupolas, ferrous and non-ferrous blast furnaces, and shaft furnaces in the absence of the use of conventional flap valves, pressure chambers, doors or bells to prevent the exhaust gases from escaping uncontrolled to the atmosphere. In this invention, the solid charging materials are loaded at all times into the reactor through the charge duct without loss of exhaust to the atmosphere or air infiltration into the exhaust gases. A controlled post combustion is conducted when the exhaust gases contain substantial amount of combustible gases. An adjustable-high-temperature-air blast is used for reduced fuel costs. The heat of exhaust gases is transferred to the air and the waste gases are exhausted at low temperature.
