Generally, the combustible composition of domestic waste is above 30% ~ 40%, the low heating value is above 3350 kJ/kg, the moisture content of the waste is below 50%, and the waste can be incinerated spontaneously. However, under this condition, the waste incineration cannot meet the requirement of 850 ℃/2S for flue gas in the furnace. The low heating value of domestic waste is above 6280 kJ/kg, which can realize stable combustion. It can not only meet the requirement of 850 ℃/2S flue gas in the furnace, but also meet the need of working medium power generation, effectively utilize energy and build a waste incineration power plant.越王得到消息后亲自率军前去营救，遗憾未能赶上，不过救出了项羽遗孤和一些西楚国将领，并抢回了项羽夫妇的遗体。此剧讲述了像童话里走向happy ending，很快就要开始幸福的一对30代情侣开始准备结婚后从而发生的左冲右撞共鸣现实爱情故事。The citizens of Hope Valley make arrangements to help the recently displaced settlers, during the Christmas season.
