摘要
为了解决冬季北京市天然气供需不平衡的矛盾,提出了6种应急气源方案:1.引进液化天然气;2.采用液化石油气混空气;3.采用液化石油气掺混天然气;4.采用现有的煤制气;5.煤制气或油制气掺混天然气;6.煤制气或油制气掺混LPG。通过华白数和燃烧势的理论计算和分析,否定了方案4和5;方案6在理论计算上是可行的,但由于混合气的供气能力小,因此也不可行。
In order to resolve the contradiction of unbalance between supply and demand of natural gas in winter in Beijing City, six kinds of schemes for emergency gas sources are put forward： 1. introduce liquefied natural gas; 2. adopt LPG-air mixture; 3. adopt LPG and natural gas mixture; 4. use coal gas or oil gas; 5. use coal gas or oil gas and natural gas mixture; 6. use coal gas or oil gas and LPG mixture. The schemes No 4 and 5 are denied by calculating Wobbe index and combustion potential. The scheme No 6 is feasible only on the basis of theoretical calculation, but it is also denied due to limited capacity of coal gas or oil gas supply.
