Title:
燃料ガス製造装置の運転方法
Document Type and Number:
Japanese Patent JP6707049
Kind Code:
B2
Abstract:
Provided is a method for operating a fuel gas manufacturing device for stopping the operation in such a manner that the operation can be immediately resumed, while keeping facilities from becoming complex. When stopping the operation while supply of source gas to a desulfurizing unit 3 is stopped, after supply of source gas to the desulfurizing unit 3 and discharge of fuel gas G to the outside are stopped, a standby operation process is performed in which fuel gas G is circulated by a circulation driving unit 7 in such a manner that the whole amount of fuel gas G passed through a moisture removing unit H is circulated through a circulation gas path R to return to the desulfurizing unit 3 and the circulated fuel gas G is heated by a heating unit to a set standby temperature to heat a reforming unit 5 to a temperature that is equivalent to an operation temperature at which reforming is performed, and supply of water vapor J is continued in a state where a supply amount of water vapor J is at least an amount with which carbon deposition due to thermal decomposition of fuel gas G can be prevented and is smaller than an amount that is supplied when reforming is performed.
