摘要:
A home fuel gas refining system has a modifier for modifying a hydrogen-containing fuel to produce a modified gas. The modifier includes a hydrogen-containing fuel supply mechanism for supplying the hydrogen-containing fuel and a modifying air supply mechanism for supplying modifying air. The hydrogen-containing fuel delivered from the hydrogen-containing fuel supply mechanism and the modifying air delivered from the modifying air supply mechanism are mixed with each other by a modification fuel ejector, and then delivered to a reactor.

A residual gas supply means includes a residual gas passage connected to a PSA mechanism and a heater, and a branch passage having opposite ends connected to the residual gas passage and branched from the residual gas passage. The residual gas passage has an opening-adjustable valve having an adjustable opening positioned between the connected opposite ends of the branch passage. The branch passage has a check valve, a chamber for storing the residual gas, and an on-off valve.
摘要:
An ECU detects various conditions of a home fuel gas refining system before starting operation of the home fuel gas refining system using pressure sensors and temperature sensors. Then, it is determined whether the detected conditions are abnormal or not. If abnormal conditions are determined, a self-repair process is performed for a predetermined abnormal condition among the conditions determined as abnormal.
摘要:
When a shutoff signal is entered to shut off a fuel gas manufacturing apparatus, it is determined whether a PSA mechanism is in a prescribed shutoff state or not. If the PSA mechanism is judged as not being in the prescribed shutoff state, the fuel gas manufacturing apparatus is continuously operated until the PSA mechanism is brought into the prescribed shutoff state. Then, if the PSA mechanism reaches the prescribed shutoff state, the fuel gas manufacturing apparatus is shut off.

摘要:
A PSA mechanism has a plurality of adsorption towers having inlet/outlet ends connected to respective valves that are connected to an off-gas discharge passage. The off-gas discharge passage is connected to an off-gas ejector of a residual gas supply. The off-gas ejector has a function to draw an off gas from the PSA mechanism with compressed air that is caused by an air compressor to flow from an off-gas discharging air supply passage into an off-gas passage.

摘要:
A PSA mechanism has adsorption towers. Cleaning valves and off gas valves are connected to the adsorption towers. Valve positions of at least either the cleaning valves or the off gas valves are determined based on an operation suspension period of the PSA mechanism or internal conditions which vary depending on the operation suspension period.
