背景技术 Background technique

[0002] 随着我国工业化程度和节能减排工作的不断发展,能源尤其是清洁能源的需求和使用问题越来越突出。 [0002] With the development of industrialization and energy conservation in our country, especially in energy demand and use of clean energy and more prominent. 天然气作为能源使用,具备高效和清洁的双重优点,近年来在国内外得到大幅应用。 The use of natural gas as an energy source, with high efficiency and clean the dual advantages, at home and abroad in recent years has been greatly used. 我国国家能源局提出:到2020年将天然气在一次能源中的比例提高到12%。 Our proposed National Energy Board: 2020 natural gas in primary energy is increased to 12%. 预计到2020年,我国天然气进口将达到每年1500亿立方米。 2020, China's natural gas imports will reach 150 billion cubic meters per year. 为了便于储存和运输,天然气需被液化成低温的液化天然气(简称LNG),在供给用户使用时,需要再将LNG气化使用。 In order to facilitate storage and transport liquefied natural gas needs to be as low temperature liquefied natural gas (referred to as LNG), the user is supplied, as necessary, and the use of LNG gasification. 气化器是国际上常用的LNG气化设备,但国产气化器气化能力尚不足,因此研制具有较大气化能力的气化设备势在必行。 The gasifier is commonly used in LNG gasification facility on international, but domestic capacity is still inadequate gasifier gasification, gasification equipment developed with the larger imperative gasification capacity.

[0003] 浸没燃烧式气化器(SCV)的作用是把LNG接收站的低温LNG加热气化并过热至0°C以上天然气(NG),然后送入管道外输至用户。 Effect [0003] submerged combustion vaporizer (SCV) cryogenic LNG is heated and vaporized LNG terminal superheated to above 0 ° C Gas (NG), and then fed to a pipeline-user. SCV的气化量可以在10%〜100%的范围内进行调节,能对负荷的突然变化做出反应,特别适合于负荷变化幅度比较大的情况。 SCV may be vaporized in an amount within the range of 10% ~ 100% of the regulation, can react to sudden changes in the load, the load is particularly suitable for relatively large changes in amplitude.
