▎ 摘　　要

NOVELTY - The equipment has a gas-water dual-heat heater inner tank that is installed in a gas-water dual-heat heater housing. A fifth raphene electric heating film is installed in the gas-water dual heating heater liner. A first graphene heating film is installed in a convection hot gas outlet. A second graphene electric heating film is installed in a convection cold air inlet for gas heating to form graphene electric heating gas water dual heating heater. A large boiler upper communication pipe is installed in a graphene electric heating boiler housing. A lower communication pipe of the large boiler is installed. A large boiler vacuum pipe is installed between an upper boiler communication pipe and a lower boiler communication pipe. A second graphene electric heating film is installed on the lower half of the large boiler vacuum tube. A first graphene electric heating film is installed in the lower communication pipe of the large boiler to form a graphene central heating electric boiler. USE - Series of energy-saving heating equipment of graphene electric heating film. ADVANTAGE - The energy is saved, the heating issues in the cold regions in the north are solved, helped to realize the coal-to-electricity reform plan, popularized in cities and rural areas, and provided with good economic benefit prospects. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the series of energy-saving heating equipment of graphene electric heating film.
