GAS GENERATOR BASED INSTALLATION FOR WASTE WOOD RECYCLING Russian patent published in 2009 - IPC F23B99/00 F23G5/00 

FIELD: machine building.

SUBSTANCE: invention deals with development of a device for recycling waste wood with the help of a gas generator that may be utilised for production of thermal and electric energy. The proposed gas generator based installation for waste wood recycling consists of a vertically positioned housing with a wood fuel supply bin mounted inside it, a fuel refilling hatch arranged in the housing upper part which hatch is connected to the wood fuel delivery system via an auger feeder and a furnace installation with a fire grate arranged in the housing lower part. Over the fire grate there is a manifold mounted with vans for delivery of air into the furnace installation combustion zone. Between the walls of the housing and the wood fuel supply bin there is a cavity arranged. Additionally the installation is equipped with generator gas preliminary and final filters, a gas glow plug and a blender connected with each other and with the cavity arranged between the walls of the housing and the wood fuel supply bin via mains that also connect the gas generator to the gas diesel engine connected to the electric power generator. The installation is equipped with an computer-aided automated system of control over the generator gas and electric energy production process. The system computer is connected, on the one hand, to a device performing analogue-to-digital conversion of signals per controllable setup parameter and on the other - to a digital-to-analogue converter of signals. The analogue-to-digital converter of signals is connected, first, to the converter of active power of the three-phase current in the electric load circuit of the electric power generator (connected to the installation power distribution board), second - to the fuel pump mounted rotational velocity sensor of the gas diesel engine crankshaft and third - to the fuel level sensor installed inside the gas generator fuel supply bin. The digital-to-analogue converter of signals is connected to three adapters: the first one installed in the electric drive of the wood fuel delivery system auger feeder, the second one, connected to the manifold with vans for delivery of air into the furnace installation combustion zone, and the third one, installed inside the blender housing to provide for control over generator gas flow.

EFFECT: increase of the installation efficiency and improvement of its environmental friendliness indices due to deployment of a computer integrated with adaptation units for control and optimisation of parameters in the course of generator gas output and installation utilisation for thermal and electric energy production.
