▎ 摘　　要

NOVELTY - The furnace has a U-shaped pipe (1) whose top end is provided with a connecting pipe (2). A left side of a left pipe is selected as a water inlet pipe (3). A right pipe of an upper pipe is selected a water outlet pipe (4). A graphene coating is sprayed on an outside of an outer surface of the U-shaped pipe. An insulating coating (501) is provided with an outside a graphene coating. An electrode lead is arranged between the graphene coating and the insulating coating. The graphene coating and the electrode lead are glued by a graphite conductive adhesive. The U-shaped pipe is fixedly connected to a shell (6) by a fastener. USE - Graphene heating furnace for use in cleaning heating technology field. Can also be used in electric heater, electric water heater, and electric boiler. ADVANTAGE - The furnace can save nickel, copper, cobalt, nickel-iron-titanium (Ni, Cr, Nb, Ti, Mo), rare mineral resources, rich resource of carbon, wide distribution, easy to obtain, and save rare mineral resource with strategic significance. The furnace is simple in structure, and can be manufactured in a cost-effective manner. DESCRIPTION OF DRAWING(S) - The drawing shows a main view of the graphene heating furnace. 2Outlet pipe 3Water inlet pipe 4Water outlet pipe 6Shell 201Heat-resistant silica gel joint 202Throat hoop 204Connecting pipe 401Heat-resistant silica gel joint 402Throat hoop 403Nut 404Connecting pipe 501Insulating insulating coating
