NOVELTY - The plant (100) has a power unit (101) mounted on a lowboy trailer (104), where the power unit includes a gear driven steam engine. A drive shaft (103) connects a generator to the power unit. The power unit and the generator are mounted to the same lowboy trailer. An operator station is replaced with a feed trough (105). A fire box (106) receives a flammable product from the feed trough. The fire box is coupled to the power unit. A water boiler (112) associated with the power unit is enhanced with a set of safety features including a set of pressure release valves.    USE - Mobile biomass generating plant for producing electric power in an affected area e.g. home and building, using waste or debris material. Uses include but are not limited to grass material, leave material, pine cone material, needle material, scrap tire material, shingle material, understory material, destroyed wood material, tree material, paper material, board material, pellet material, scrap wood material, farm waste material, corn stalk material, wheat straw material, saw dust material, wood scrape material and farm waste material.    ADVANTAGE - The plant allows the power unit to include the gear driven steam engine mounted on the lowboy trailer to produce heat and boils quantity of water in the boiler of the gear driven steam engine using the heat produced by burning the biomass, so that the steam produced by the boiling water can run pistons on the gear driven steam engine, thus turning the drive shaft to spin the generator connected to the gear driven steam engine via the drive shaft and producing the electric power, and hence repairing electrical problems in a quick and timely manner in the affected area. The plant allows the boiler to be outfitted with stronger steel and safety features to prevent boiler failure. The plant allows the wood product/biomass to be squeezed of moisture to reduce need for drying. The plant dries the wood products/biomass to enable the product to burn, thus causing the boiler to reach appropriate temperature.    DETAILED DESCRIPTION - The power unit is selected from a group consisting of Heisler gear driven train and Shay gear driven train. The gear driven steam engine includes an air quality system selected from a group consisting of catalytic converter and ammonia solution system. An INDEPENDENT CLAIM is also included for a method for using a mobile biomass generating plant to produce electric power.
