Предложена доменная печь, в которой вместо фурм установлены плазмотроны, состоящие из двух графитовых электродов в виде труб, вставленных соосно одна в другую с зазором между ними. Дугу зажигают в зазоре между трубами на концах труб, расположенных внутри печи, и продувают через зазор между трубами плазмообразующий газ - воздух или кислород при традиционной доменной шихте или водород, метан, природный газ при шихте без кокса. Благодаря высокой температуре плазмы, вдуваемой в домну, скорость плавки возрастает, а расход кокса уменьшается. Кроме того, при вдувании в печь восстановительных газов в ней можно получать сталь и железо, что невозможно в традиционной доменной печи.A blast furnace was proposed, in which instead of tuyeres plasmatrons were installed, consisting of two graphite electrodes in the form of tubes inserted coaxially into one another with a gap between them. The arc is ignited in the gap between the pipes at the ends of the pipes located inside the furnace, and the plasma-forming gas — air or oxygen in the traditional blast furnace mixture or hydrogen, methane, natural gas in the mixture without coke — is blown through the gap between the pipes. Due to the high temperature of the plasma injected into the blast furnace, the melting rate increases, and the coke consumption decreases. In addition, by blowing reducing gases into the furnace, it is possible to produce steel and iron, which is impossible in a traditional blast furnace.
