1. An automated biomass distribution system comprising:
i) a local control device unit adapted to generate a set of control signals; ii) a set of converters connected to said local control device, wherein each converter within said set of converters is adapted to receive a subset of control signals of said set of control signals and convert said received subset of control signals into a set of air pressure signals; iii) a set of actuators connected to said set of converters respectively, wherein each actuator within said set of actuators receives said set of air pressure signals from a corresponding converter within said set of converters; iv) a set of valve plugs operatively coupled to said set of actuators through a set of spindles respectively, wherein each valve plug within said set of valve plugs is actuated by a corresponding actuator within said set of actuators through a spindle within said set of spindles in response to each air pressure signal within said set of air pressure signals; and v) a set of discharge ducts operatively coupled to a set of biomass distributors, wherein:
1) said set of biomass distributors are attached to a furnace of a boiler stoker and adapted to receive biomass, wherein said furnace includes a grate for burning said biomass; and2) each discharge duct within said set of discharge ducts receives a portion of a corresponding valve plug within said set of valve plugs to form a throttling passage to regulate airflow moving into a corresponding biomass distributor through said throttling passage, wherein said airflow moves biomass over said grate, a nozzle pressure of said airflow corresponds to an air pressure signal within said set of air pressure signals, and said airflow is provided by an air supplier through a main duct. |
