我国生产的二甲醚(DME),曾被大量用于掺入液化石油气中燃烧。虽然二甲醚可作为燃料,但其热值比液化石油气低,在产生同样热量的情况下,需要消耗更多的二甲醚。近年,二甲醚价格约为液化石油气的三分之二,综合考虑,作为燃料,二甲醚并不具有明显的价格优势。但如果将二甲醚掺入液化石油气中,按照液化石油气价格销售,则可以带来暴利。有报道称,如果在液化石油气钢瓶中掺入二甲醚,在不改变燃具情况下,燃烧中空气过剩时易出现 China’s production of dimethyl ether (DME), has been used extensively for burning liquefied petroleum gas. Although dimethyl ether can be used as a fuel, its heating value is lower than liquefied petroleum gas, which consumes more DME when it produces the same amount of heat. In recent years, DME prices are about two-thirds of LPG, considering, as a fuel, DME does not have obvious price advantage. However, if DME is blended into liquefied petroleum gas and sold according to the price of liquefied petroleum gas, it can bring huge profits. It is reported that if LPG cylinders are mixed with DME, it is easy to appear when there is excess air in the combustion without changing the burning appliance
