Abstract

The invention provides a three-time air supply methanol-to-hydrogen combustion evaporator which comprises a heat exchanger, a combustion evaporator body, a combustion chamber and a three-time air supply device, the air outlet end of the heat exchanger communicates with the three-time air supply device, and the three-time air supply device is arranged at the top of the combustion chamber. The tertiary air supply device blows flames generated during combustion of the combustion chamber to the combustion evaporator, the heat exchanger is used for preheating normal-temperature air, and the tertiary air supply device supplies air to the combustion chamber. The three-time air supply design is adopted, so that combustion is more complete, the flame temperature distribution is uniform, the heat efficiency is greatly improved, and fuel waste is reduced. Through gas preheating and waste heat recovery, external energy input is reduced, the operation cost of the system is remarkably reduced, and the energy-saving and environment-friendly trend is met. The high-temperature gas guide pipe guides waste heat back to the heat exchanger, heat energy recycling is achieved, the overall heat energy utilization rate is increased, and emission loss is reduced.
