In recent years, the field of coal-fired boilers is continuously updated, and aiming at the problems existing in the use of the existing coal-fired boilers, the coal-fired boilers are continuously optimized in the aspects of energy conservation, emission reduction, energy consumption reduction and the like. Especially, how to improve the combustion efficiency of coal, and the combustion in the furnace is an integral coal powder oxidation heating process, we can divide it into two aspects: firstly, the combustion condition that stove wind coal ratio, one overgrate air ratio, combustor operating mode formed, firstly come from the influence of tertiary air and external world (mainly negative pressure, hourglass etc.), promptly also the disturbance of tertiary air and external world to the stove burning operating mode. Whether the combustion is stable depends on whether the combustion working condition in the furnace can resist tertiary air and external disturbance, and the reasonable air-coal ratio, namely the optimal surplus air amount is kept, namely the reasonable oxygen amount value is kept. The existing coal combustion boiler generally conveys coal into the boiler, and the conveyed coal is different in size, so that the coal is not beneficial to combustion and effective utilization;
since hydrogen is mainly derived from synthesis gas containing hydrogen and carbon monoxide (pure hydrogen also results from the electrolysis of water). The mixed gas composed of nitrogen and hydrogen is the raw material gas for synthesizing ammonia.
