The gasification reaction of the gasification furnace 12 produces a high temperature synthesis gas, which is then purified at a low temperature, and thus the synthesis gas is cooled by the synthesis gas cooler 131, and sensible heat of the high temperature synthesis gas during the cooling process is recovered by the condensed feed water of the steam turbine 32. The synthesis gas dust remover 132 can remove fly ash in the synthesis gas, the synthesis gas desulfurizer 133 can remove sulfur and the like in the synthesis gas, the sulfur content in the synthesis gas is less than 1ppm before the synthesis gas enters the fuel cell 23, and the purification of the synthesis gas does not need to remove CO2。

The fuel cell 23 is normally in operation, i.e. the anode and cathode of the fuel cell 23 are fed with synthesis gas and oxygen respectively to generate electricity by combustion, however, the fuel cell 23 will undergo start-up temperature raising phase at the beginning of the start-up temperature raising phase, the anode and cathode of the fuel cell 23 need to be preheated by high-temperature oxygen and nitrogen respectively, at this time, nitrogen is fed into the anode of the fuel cell 23 instead of oxygen.

The flue gas of the oxygen preheater and the flue gas of the synthesis gas preheater 21 are connected in series, so that the flue gas is ensured not to generate a blocking phenomenon due to different resistances of the downstream heat exchanger, and the flow of the distributed flue gas does not need to be adjusted in proportion.
When the fuel cell unit is in a starting temperature-rising stage, the nitrogen preheater and the oxygen preheater are opened, and the synthesis gas preheater is closed; when the fuel cell is in the run phase, the syngas preheater and the oxygen preheater are turned on, and the nitrogen preheater is turned off.

Because the tail gas of the fuel cell 23 is oxygen and nitrogen at the start-up temperature-raising stage and cannot be input into the tail gas combustion furnace 31 for combustion and power generation, the oxygen and the nitrogen are directly input into the tail gas combustion furnace 31 so as to obtain high-temperature flue gas at the start-up temperature-raising stage to preheat the nitrogen and the oxygen.
In this embodiment, the oxygen for the gasification furnace 12, the oxygen for the cathode of the fuel cell 23, and the oxygen for starting combustion are all separated from the compressed air by the air separator 144, and the oxygen obtained by the air separator 144 can improve the conversion efficiency of the gasification furnace 12 and the fuel utilization rate of the fuel cell 23 and the tail gas combustion furnace 31. And the nitrogen gas as the byproduct of the air distribution unit 144 can be used as the pressurized gas of the gasification furnace 12 and the protective gas in the starting and temperature-rising stage of the fuel cell 23, and in the starting and temperature-rising stage of the fuel cell 23, the high-temperature flue gas discharged from the tail gas combustion furnace 31 preheats the protective nitrogen gas and the oxygen gas, the temperature after preheating the nitrogen gas is 700 ℃ and the temperature after preheating the oxygen gas is 900 ℃, the preheated nitrogen gas and the preheated oxygen gas are respectively introduced into the anode and the cathode of the fuel cell 23 for preheating and temperature-rising, so as to ensure the temperature balance of the cathode and the anode.

In order to maintain the steam amount and the pre-valve temperature of the steam turbine 32, the feed water is directly heated by the off-gas burner 31 and joined with the steam of the water produced by the gasification furnace 12 to enter the steam turbine 32. Because the amount and temperature of the steam formed by the gasification furnace 12 are often unstable, the steam of the tail gas combustion furnace 31 enters a high-pressure section of the turbine, and the steam of the high-temperature cooling sections of the gasification furnace 12 and the synthesis gas cooler 131 enters a low-pressure section of the turbine to do work, wherein the parameters of the high-pressure section and the low-pressure section are respectively 10Mpa and 1 Mpa.

Sensible heat of a low-temperature cooling section of the synthesis gas cooler 131 is used for heating feed water, the feed water is led out from the outlet of the feed water pump 34 and is heated and then returned to the front of the deaerator 35, the cogeneration system fully utilizes the temperature of each gradient section, and single-cycle waste heat is changed into combined cycle systemEnergy consumption is greatly reduced
