However, such conventional coal supply devices have the following problems. Generally, in a lock hopper system for supplying coal to a gasifier, receiving coal from upstream equipment to the hopper and supplying coal to the downstream side are performed alternately. When receiving coal, the gas in the hopper is released to the outside to reduce the pressure, and after receiving the coal, it is pressurized again with gas and supplied to the downstream side. Therefore, a large amount of N 2 gas is always required, and a large N 2 storage facility is required. In addition, for this reason, liquid nitrogen must be frequently received from outside by means such as tank trucks, which increases the complexity of operation and management.
上記のほか、ガス化炉構成各部の、起動・停止
