Embodiment 1

[0034] Embodiment 1, when the fuel is methane, the working principle of the present invention is:

[0035] To ensure the normal operation of the equipment, close the under-oxidation reforming flow control valve 12, the solenoid valve 19 of the hot air recovery channel, and open the manual valve 18 of the hot air recovery channel, and make the combustion chamber reach the preset temperature of 650±10°C by adjusting the flow of methane and temperature-adjusting air .

[0036] After the SOFC stack is preheated for 10 minutes, open and close the under-oxidation reforming flow control valve 12, close the manual valve 18 of the hot air recovery channel, and open the solenoid valve 19 of the hot air recovery channel to start the entire gas circuit system. The carbon monoxide and hydrogen in the reforming chamber 14 provide the carbon monoxide and hydrogen required for power generation to the electric stack through the gas channel, and the electric power generated by the SOFC electric...

Embodiment 2

[0041] Embodiment two, when the fuel is propane, the working principle of the present invention is:

[0042] To ensure the normal operation of the equipment, close the under-oxidation reforming flow control valve 12, the solenoid valve 19 of the hot air recovery channel, and open the manual valve 18 of the hot air recovery channel, and make the combustion chamber reach the preset temperature of 650±10°C by adjusting the flow rate of propane and temperature adjustment .

[0043] After the SOFC stack is preheated for 10 minutes, open and close the under-oxidation reforming flow control valve 12, close the manual valve 18 of the hot air recovery channel, and open the solenoid valve 19 of the hot air recovery channel to start the entire gas circuit system. The carbon monoxide and hydrogen in the reforming chamber 14 provide the carbon monoxide and hydrogen required for power generation to the electric stack through the gas channel, and the electric power generated by the SOFC elec...

Abstract

The invention discloses a movable solid oxide fuel cell power generation apparatus adopting an intelligent combustor for heating. The movable solid oxide fuel cell power generation apparatus comprises a cylindrical combustion cavity, a fuel gas channel, an SOFC (solid oxide fuel cell) electric pile, a micro control unit, an uninterruptible power supply (UPS), a temperature sensor, and an SOFC gas-supply path, wherein the fuel gas channel is connected with the cylindrical combustion cavity; the SOFC electric pile is arranged in the cylindrical combustion cavity; the UPS is connected with the SOFC electric pile; the temperature sensor is arranged in the cylindrical combustion cavity; the SOFC gas-supply path is connected with the fuel gas path and the SOFC electric pile, wherein a hot air recycling channel is formed in the outer wall of the cylindrical combustion cavity; the hot air recycling channel is connected with a reforming chamber; and a hot air recycling channel electromagnetic valve is arranged on the hot air recycling channel between the cylindrical combustion cavity and the reforming chamber. Compared with the prior art, the movable solid oxide fuel cell power generation apparatus is free from an external power supply, convenient to move, capable of recycling waste hot air afterheat for reforming the fuel gas, intelligently controlled, and convenient to use.

Description

technical field [0001] The invention relates to a solid oxide fuel cell power generation device, in particular to a movable solid oxide fuel cell power generation device heated by an intelligent burner. Background technique [0002] A solid oxide fuel cell (SOFC) is a power generating device that converts chemical energy in hydrocarbon fuels into electrical energy. The so-called hydrocarbon fuels here include: natural gas, coal gas, gasoline or diesel oil, etc. The use of SOFC for energy conversion has no combustion and mechanical processes, thereby greatly improving the energy conversion efficiency, and it is quiet and reliable, and has a good guarantee for the quality of power. According to the demand of electricity consumption, SOFC can flexibly increase or decrease the power supply capacity of the power station. SOFC is an independent power generation system that can be conveniently applied where electricity is needed without expensive power transmission systems. This...
