随着我国城市煤气事业的发展,多气源(焦炉煤气、天然气和液化石油气等)供气的城市也在不断地增加,这给煤气灶具提出了一个适应性的问题。无论是瓶装的液化石油气,还是管道供应的天然气和焦炉煤气,其成份是经常变化的。这是因为液化石油气由于原油不同,组成也不同;就是同一瓶液化石油气也存在上瓶与底瓶的差异。同样,天然气和焦炉煤气组成也随客观因素(如气田、制气煤种、炉型的不同)和人为因素而波动。随着城市煤气供气量急骤增长,必然会造成供应中出现所谓“用气高峰”。为了保证供应,填补供应差额,通常按比例以油制气+水煤气+发生炉煤气或液化石油气混
With the development of China’s urban gas industry, the number of cities supplying more gas (such as coke oven gas, natural gas, and liquefied petroleum gas) is also increasing, which raises a problem of adaptability to gas cookers. Whether it is bottled liquefied petroleum gas or natural gas and coke oven gas supplied by pipelines, its composition is constantly changing. This is because the liquefied petroleum gas has different compositions due to different crude oils; that is, there is also a difference between the upper bottle and the bottom bottle in the same bottle of liquefied petroleum gas. Similarly, the composition of natural gas and coke oven gas also fluctuates with objective factors (such as gas fields, gas coal, furnace type) and human factors. With the rapid increase in urban gas supply, there will inevitably be a so-called “peak of gas use” in supply. In order to ensure supply and fill the supply gap, oil gas, water gas, producer gas or liquefied petroleum gas
