Description

technical field [0001] The invention relates to an LNG heating gasification device, in particular to an LNG heating gasification device suitable for use in small and medium-sized areas. Background technique [0002] Natural gas is a combustible gas that is naturally mined in the gas field. The main components are methane, ethane and other gases. At the time of consensus, natural gas is becoming more and more popular as a clean energy source, and many countries have listed it as the preferred fuel. The proportion of natural gas in energy supply has increased rapidly, so it has become one of the directions of world energy development. According to China's natural gas use plan, domestic production capacity will reach 90 billion cubic meters in 2010, and will reach 240 billion cubic meters by 2020. In terms of imported natural gas, the National Development and Reform Commission predicts that by 2020, China will import 35 billion cubic meters, equivalent to At 25 million tons / ye...

Problems solved by technology

At present, in the communities of some large and medium cities, it is especially necessary to adapt to the small and medium-scale gas supply, that is, the gas supply per hour is about 5,000 to 10,000 cubic meters, and the structure is compact, the investment is low, the thermal efficiency is high, and the gas supply speed is fast. , suitable for peak-shaving heating and gasification devices. Looking at the above-mentioned prior art heating and gasification furnaces, they are not suitable, or the structure is too complicated, the investment is high, and the daily gas supply is too large or too small, which is not suitable for regional life supply. or the heating and gasification is unstable, the gasification rate and thermal efficiency are low, and cannot be adjusted automatically, and cannot meet the occasions with large differences between peaks and valleys. Therefore, changes and improvements are urgently needed
