A boiler plant includes a carbon dioxide capture system. The carbon dioxide capture system has an absorbing-liquid regeneration device and an absorber. The absorbing-liquid regeneration device includes a regenerator, a first circulation line in which the absorbing liquid is taken out from the regenerator and is returned to the regenerator, and a second circulation line in which the absorbing liquid is taken out from the regenerator and is returned to the regenerator, a heat exchanger, a heater, and a switcher. The heat exchanger heats the absorbing liquid by exchanging heat between the absorbing liquid flowing through the first circulation line and steam from the boiler. The heater heats the absorbing liquid flowing in the second circulation line. The switcher switches between a first heating state, in which the absorbing liquid flows in the first circulation line, and a second heating state, in which the absorbing liquid flows in the second circulation line.

A gasification facility which uses flammable gas as a carrier medium for air-transporting powder fuel, used as a gasification raw material, to a gasification furnace and which can safely release the flammable gas, exhausted from a fuel feed hopper, to the atmosphere. In the gasification facility using flammable gas as a carrier medium for transporting pulverized coal as powder fuel from a pulverized coal feed hopper () to a gasification furnace (), the flammable gas discharged from the pulverized coal feed hopper () is subjected to incineration treatment and then released to the atmosphere, so that safe release to the atmosphere can be implemented.

Provided is a coal gasifier enabling a reduction in size of a shift reactor by generating hydrogen-rich gasified coal gas. In a coal gasifier (G) generating gasified coal gas by a gasification reaction proceeding in a furnace fed with a gasifiable raw material, such as coal, and a gasifying agent, at least one of water and steam is fed to the furnace as a material accelerating a hydrogen-generating reaction that proceeds simultaneously with the gasification reaction.

Coal gasifier

Synthesis gas (syngas) gasified in a gasification furnace to which coal is introduced burns in a combustor. An exhaust-heat recovery boiler generates steam by using exhaust gas let out from a gas turbine equipped with the combustor. The steam generated in the exhaust-heat recovery boiler is introduced to a steam turbine. A generator is driven by the steam turbine and the gas turbine to generate electrical power. Part of the exhaust gas let out from the gas turbine is introduced to a carbon-dioxide recovery unit, where carbon dioxide is recovered therefrom. Coal is carried to the gasification furnace by the carbon dioxide.

In a coal gasification furnace adapted to feed pulverized coal thereinto by the use of inert carrier gas and gasify the same, any startup burner can be unnecessitated thereby eliminating any startup combustion chamber. Further, even in the use of a startup burner, it is smaller and lighter in weight than conventional startup burners, allowing the startup combustion chamber to be compact and limiting the height of the entirety of the gasification furnace. As a characteristic feature, a pulverized coal fuel supply passageway () to a combustor burner () is provided at its midstream portion with a startup gas supply passageway () for supply of a startup combustible gas (NG). After reaching of the temperature of the furnace interior to a first temperature (T) allowing ignition of pulverized coal with reference to a detected value from furnace interior temperature detecting means (), transition to combustion by the pulverized coal and carrier gas is effected by increasing the input rate of pulverized coal and carrier gas while decreasing the supply rate of combustible gas (NG) from the startup gas supply passageway ().
