BIOGAS BAR-GALVANIC ELECTRIC HEAT GENERATOR WITH HEAT REGENERATION OF WORKING FLUID Russian patent published in 2012 - IPC H01M14/00 G01K17/00 

FIELD: power engineering.

SUBSTANCE: biogas bar-galvanic electric heat generator comprises the following: a cylindrical vessel-jacket with legs, a perforated base and a side ignition-sight opening; a coaxially cylindrical track of vertical upward movement of combustion products with a gas flow turbulator; the main gas burner in the form of a tubular hoop with even arrangement of holes in it for biogas discharge and the main supply pipeline of biogas with a manually driven valve; an ignition burner with a supply biogas pipeline; a coaxial cylindrical cooler of a heating system with a liquid coolant that circulates through it with an electrically driven valve at the inlet and a manually driven valve at the outlet. A condenser is made in the form of a coaxial cylinder, which is equidistantly arranged inside the cooler; an umbrella with a fairing; a hot water supply circuit heat exchanger with manually driven valves at the inlet and outlet, at the same time the heat exchange is made in the form of a coaxial cylinder, the inner cylindrical surface of which is brought into tight thermal contact with the external cylindrical surface of the track of combustion products movement in its end upper part; a unit of safe operation automation by draught and thermal control, comprising a magnetic gas valve providing for full termination of biogas supply to the main and ignition burners as flame goes off in the last one; a thermal controller providing for automatic control of a coolant temperature in a cooler. The automation unit is connected to the biogas supply pipeline with a manual valve, discharge biogas pipelines to ignition and main burners, a draught sensor, thermocouples and a valve electric drive at the inlet to the cooler; a flue and thermal insulation of the units, at the same time a power generating cell is made in the form of a coaxial cylinder, the inner cylindrical surface of which that limits the high-pressure cavity, is brought into a tight thermal contact with the external surface of the coaxially cylindrical track of combustion products movement in its central part, and electrodes and electrolyte are made in the form of cylinders, separated into sections with dielectric substrates between them, at the same time electrodes are switched along electricity via pin sealed lead-ins pulled via dielectric substrates; an overheating evaporator is made in the form of a coaxial cylinder, the inner cylindrical surface of which is put into a tight thermal contact with the external surface of the cylindrical track of combustion products movement in its lower part, at the same time the overheating evaporator and a regenerative heat exchanger are located under the power generating cell.

EFFECT: reduced specific cost of produced power with simultaneous recycling of burned biogas heat for heating and hot water supply to a power autonomous house.
