FIELD: power industry.
SUBSTANCE: in system (1) of fuel element, fuel element (2) operates at closed channel (8) for fuel gas extraction. Foreign materials accumulated in channel (8) are released upon blowoff valve opening (8). When element voltage, measured by voltage measuring device (11), is not lower than pre-set value, this invention actuates blowing limiting device (13), which prevents from blowing.
EFFECT: releasing foreign materials, accumulated on the side of anode, besides preventing from carbon oxidation reaction in the system of fuel pocket, based on dead end method.
