coal hopper的意思|示意

Coal hopper（煤舱）is a type of container used for the transportation and storage of coal or other fossil fuels. It is usually a large container attached to the railroad track and designed to keep the coal from spilling, as well as to facilitate loading or unloading.

Coal hoppers are usually used to transport coal from one source to another. For example, a hopper car can take coal from a mineshaft to a distant power plant. The coal hoppers can be filled with coal at the mine, and when they reach the power plant, they are unloaded and the coal is burned in the furnace to generate electricity.

Coal hoppers are also used to store coal at the power plant, in order to ensure an adequate supply of coal during periods when the plant is not operating. In addition, they can be used as temporary storage for coal in the event of a power outage.

Coal hoppers can vary in size and capacity. Some are very small and can hold only a few tons of coal, while others are large and can hold up to three thousand tons. They are usually made from a combination of metal and plastic, and some are designed to be watertight.

A coal hopper is an important part of the coal supply chain, as it helps to ensure a steady and reliable source of coal to power plants. It is also a very useful tool for transporting and storing coal, as it helps to keep the coal from spilling and enables efficient loading and unloading.
