Electromagnetic-induction heating high-temperature fused salt heat carrier furnace

Abstract

The invention discloses an electromagnetic-induction heating high-temperature fused salt heat carrier furnace which is characterized by comprising an upper medium bin (1), a lower medium bin (10) and a heat carrier bin (2), wherein a heat exchanger pipe bundle (3) is arranged in the heat carrier bin (2); the upper medium bin (1), the lower medium bin (10) and the heat exchanger pipe bundle (3) form a heat exchanger; a heat-insulated layer (4) is arranged outside the furnace body; an inductor insulating bracket (7) is arranged on an outer layer of the heat-insulated layer (4) in a section of the heat carrier bin (2); N inductors (8) are arranged on the inductor insulating bracket (7); a thermoelectric couple (11), a fused salt filling port and expansion tank (6) and a fused salt slag removing port (9) are arranged on the upper medium bin (1); a fused salt flowing port is arranged on the heat carrier bin (2); and a fused salt reflow port is arranged at the lower part of the heat carrierbin (2) and is communicated with a heat carrier circulating pump (5) through a pipeline. According to the furnace, the heat carrier is heated by electromagnetic induction and the medium in the heat exchanger is heated. The furnace can be applied to production of hot water, steam or petrochemical industry and other industries; heat energy utilization at high efficiency is realized; energy saving and environment friendliness are achieved; and economic benefit is improved.

Description

Technical field: [0001] The invention relates to the technical field of heat energy equipment, and belongs to heat carrier furnaces, specifically an electromagnetic induction heating high temperature molten salt heat carrier furnace, which heats the heat carrier through the electromagnetic induction furnace body to heat the medium in the heat exchanger. For heating, it can be used in the production of hot water, steam or petrochemical industries to achieve high-efficiency use of heat energy, achieve energy saving, environmental protection, and improve economic benefits. Background technique: [0002] At present, heat carrier furnaces use coal, oil, and gas as fuels, and tube furnaces use oil and gas as fuels; In general, the furnace tubes in high-temperature local areas are easy to deform and burn through, and the safety hazards are relatively serious. The organic heat carrier is easy to coke or crack when encountering high-temperature areas, which affects the normal operati...
