What has been achieved by this invention is a method and design of providing high temperature heat for an endothermic gasifier without combustion using electrical resistance immersion heating element technology. Further, these elements could be heated by three phase electrical power; thus, minimizing the number of electrical leads emerging from the top of the heating elements.
This invention solves the difficulty of designing the steam/CO2 reforming reactor with a large number of densely packed heating elements and the syngas heat recuperator into one reactor. This is done to avoid the extremely hot syngas leaving the reactor from melting the downstream metal fittings carrying the reactor product gases to the downstream piping process.
