大家知道，火力发电的主要燃料是煤。随着电力事业的发展，大容量、大机组火力发电厂在我国已占主导地位。一座100万千瓦容量的电厂，日耗燃料约1－2万吨左右，过去小电厂耗用燃料量已不可与此同日而语。燃料接、卸、供三个环节，是保证机组发电的基本条件。目前各电厂输煤系统
As we all know, the main fuel for thermal power generation is coal. With the development of the electric power industry, large-capacity, large-scale unit thermal power plants have dominated China. A power plant with a capacity of 1 million kilowatts has a daily fuel consumption of about 1-2 million tons. In the past, the amount of fuel consumed by a small power plant was no longer the same. The three links of fuel connection, unloading and supply are the basic conditions for ensuring the power generation of the generating units. Current power plant coal conveying system
