Problems solved by technology

[0003] At present, the rotary heat storage heat exchangers used in the prior art are usually contact heat exchangers, which are used in the combustion system to preheat fuel and combustion air. To ensure safety, usually only the combustion air can be preheated. , and the inability to preheat the fuel directly restricts the further improvement of combustion efficiency

Abstract

A dual-preheating rotation type heat-storage heat exchanger comprises a heat storage body, fluid passageways and a fuel passageway. The heat storage body can rotate. The fluid passageways include the hot fluid passageway and the cold fluid passageway. A hot fluid medium in the hot fluid passageway and a cold fluid medium in the cold fluid passageway can both make contact with the heat storage body. The fuel passageway comprises a passageway pipe which is arranged on the heat storage body. The dual-preheating rotation type heat-storage heat exchanger can safely and efficiently preheat fuel, and therefore the aim of improving the combustion efficiency through dual preheating is achieved. A combustion system comprises a smoke pipeline, a combustion-supporting gas pipeline, a fuel conveying passageway and the dual-preheating rotation type heat-storage heat exchanger. The dual-preheating rotation type heat-storage heat exchanger comprises the hot fluid passageway, the cold fluid passageway and the fuel passageway. The hot fluid passageway is connected with the smoke pipeline in a butt joint manner. The cold fluid passageway is connected with the combustion-supporting gas pipeline in a butt joint manner. The fuel conveying passageway is connected with the fuel passageway in a butt joint manner. The combustion system can preheat combustion-supporting air and fuel at the same time, and the combustion efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of heat exchanger equipment, more specifically, to a double preheating rotary heat storage heat exchanger and a combustion system. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. According to the principle of heat transfer, the heat exchanger includes a regenerative heat exchanger. The regenerative heat exchanger transfers heat from a high-temperature fluid to a low-temperature fluid through a heat storage body composed of solid materials. The heat medium first heats the solid material to achieve After a certain temperature, the cold medium is heated through the solid material to achieve the purpose of heat transfer. [0003] At present, the rotary heat storage heat exchangers used in the ...
