Description
Technical Field
The invention belongs to the field of fuel cells, and particularly relates to a double-path combustor for a solid fuel cell and application thereof.
Background
A Solid Oxide Fuel Cell (SOFC) is an all-solid-state chemical power generation device that directly converts chemical energy stored in fuel and oxidant into electrical energy at high temperature with high efficiency and environmental friendliness, and belongs to the third generation fuel cell. In operation the fuel is converted to synthesis gas (H) by a steam reformer2And CO), the synthesis gas and unreacted anode exhaust gas from the stack anode, the heat generated by combustion in the combustor can be provided to the fuel cell stack and the steam reformer, maintaining the electrochemical and reforming reactions.
Depending on the operational characteristics of the SOFC, the fuel concentration of the mixed gas entering the combustion chamber is lean and the excess air ratio is high (3-6), so combustion in the combustion chamber is ultra-lean. And since the power supply of the SOFC is divided into four distinct phases: the current rise stage, the hot standby stage, the self-heating maintenance stage and the system performance reduction stage cause the concentration of fuel entering the combustor to change along with the change of the power generation, and further cause the fluctuation of the flame propagation speed. Due to the fluctuation of flame propagation speed and the low fuel concentration, the combustion in the combustion chamber is very easy to be tempered or blown out, and the stability and efficiency of the whole SOFC system are very unfavorable. And in practical applications, the instability of the backfire and the misfire has not been effectively controlled, which seriously affects the healthy operation of the fuel cell.
