Abstract: An electrically powered furnace may include a plurality of heating tubes configured to receive a feed and heat the feed. Each of the plurality of heating tubes may define a longitudinal axis extending between a first end of the heating tube and a second end of the heating tube and a longitudinal passage for the feed to pass through during heating of the feed. The electrically powered furnace may also include a plurality of electrical connections electrically connecting the plurality of heating tubes, and an electrical power source electrically connected to the plurality of electrical connections and configured to supply a voltage to the plurality of electrical connections. The voltage may be greater than or equal to 20 volts. The electrical connections may electrically connect the heating tubes in series, and the furnace may be configured such that processing of the feed occurs in parallel.

Abstract: A systems and method for production of acetylene by pyrolysing a feedstock through combustion products are disclosed. The system comprises: a combustion chamber having a chamber structure including sidewalls; a first stage having one or more first inlets, the one or more first inlets having one or more first inlet directions incident to respective areas of the sidewalls at one or more first inlet angles, the one or more first inlets configured to provide fluid for combustion in the combustion chamber, the first stage producing one or more of an axial jet and a radial jet within the combustion chamber; a second stage having one or more second inlets, the one or more second inlets having one or more second inlet directions incident to respective areas of the sidewalls at one or more second inlet angles, the one or more second inlets configured to provide fluid for combustion in the combustion chamber, the second stage producing a radial jet within the combustion chamber; and a process feed for providing a feedstock acted upon by the combustion within the combustion chamber, wherein a firing rate of about 30 MMBtu/h to about 1000 MMBtu/h is exhibited in the combustion chamber.
