The key technology for developing and utilizing natural gas and the research and development of advanced equipment are the keys for ensuring the safe and stable supply of natural gas and realizing the healthy and orderly sustainable development of the natural gas industry.
The raw gas typically produced from gas wells contains small amounts of water vapor in addition to combustible hydrocarbon gases. In the exploitation and long-distance transportation of natural gas, hydrate can be separated out due to too low temperature, so that a shaft, a pipeline, a valve and equipment are blocked, even production halt and danger can be caused in severe cases, and in order to prevent the phenomenon, a large amount of natural gas heating anti-freezing equipment is required to be arranged at a wellhead, a metering station, a transfer station and the like. In the application process of natural gas, the natural gas is often required to be decompressed, when the pressure drop is large, the temperature drop of the natural gas is too large, and heating equipment is also required to be arranged; in order to meet the combustion requirements or improve the efficiency and other process requirements, a gas power plant is often provided with heating equipment to heat fuel gas. In addition, Liquefied Natural Gas (LNG) is a cryogenic fluid at-162 ℃, and can be used as a domestic gas or an industrial gas only after being heated and gasified and returned to normal temperature, so that a large amount of heating and gasifying equipment is inevitably used in an LNG distribution application system.
Generally, the heating and gasification of natural gas adopts a mode of indirect heating by an intermediate heat-carrying medium. The structure is that heating surfaces such as a fire tube and a flue gas tube bundle and cooling surfaces such as a multi-return-stroke convection tube bundle are arranged in a horizontal large cylinder, and an intermediate heat-carrying medium is filled in the cylinder and is used as a heat transfer medium between the heating surfaces and the cooling surfaces, so that the purpose of heat transfer of cold and hot fluids is achieved. Generally, heating and cooling heating surfaces are arranged in an axial symmetry mode by a central axis of a circular section of a large cylinder body, and a fire cylinder and a smoke tube bundle are positioned below a horizontal axis and are symmetrically arranged on the left side and the right side of a vertical axis; the multi-return convection tube bundle is positioned above the horizontal axis, and each return is also symmetrically arranged at the left side and the right side of the vertical axis.
The fuel is combusted in the fire tube to release chemical energy, and the combusted flue gas flows through the fire tube and the flue gas pipe bundle and is finally discharged through the chimney. The high-temperature flue gas after combustion transfers heat to the fire tube and the wall surface of the flue gas tube bundle in a radiation and convection mode, and then an intermediate heat-carrying medium is heated. The convection bank is positioned above the heating furnace and is immersed in the intermediate heat-carrying medium. The heated natural gas flows in the convection bank, absorbs heat in a forced convection heat exchange mode, and the temperature is increased. Obviously, the heat transfer form of the intermediate heat-carrying medium and the fire tube, the flue gas tube bundle and the convection tube bundle is the key influencing the heat efficiency of natural gas heating and gasification.
Due to the lack of understanding of the heating and gasification mechanism, the existing research and application technology only aims at the convection heat transfer flow field of the medium, and completely ignores the existence of the medium participation radiation. According to the various structures, the defects that the conventional arrangement mode is not beneficial to forming an effective heat transfer flow field are overcome, the effect is very limited, and sometimes even the medium participatory radiant quantity is artificially weakened, so that the problems of low natural gas heating and gasifying efficiency, slow starting, high energy consumption and the like are caused.
