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.
