Increase the amount of hydrogen gas discharged, reduce the temperature of the cold high-pressure section, improve the purity of fresh hydrogen, and enhance the desulfurization of recycled hydrogen. [Q&A Question 244] September 2, 2017. Briefly describe the function of the overhead oil tank. By adjusting the oil pressure, or in the event of an unexpected shutdown, potential energy can be utilized to provide lubrication for the hydrogen circulation pump. 【Q&A Question 245】 September 3, 2017: How to introduce fuel gas into the device? (1) Check system isolation of the process. (2) The fuel gas system meets the N2 airtightness requirements; analyze the O2 in the fuel gas system
A high oxygen content in the flue gas indicates an increased amount of air entering the furnace. This not only lowers the temperature inside the furnace, but it also increases the volume of flue gas generated due to the higher air flow, resulting in more heat being carried away during exhaust. Decrease in furnace efficiency

An excessive amount of air entering the furnace increases the oxygen content in the flue gases, thereby reducing the furnace’s thermal efficiency. On the other hand, too little air results in incomplete combustion, which also lowers the furnace’s thermal efficiency. I seek advice from those with more experience in this area.
A high oxygen content in the flue gas leads to an increased amount of air entering the furnace, which reduces the furnace temperature and affects heat transfer. At the same time, an increased volume of flue gas results in more heat being carried away, thereby reducing the efficiency of the heating furnace. A low oxygen content in the flue gas causes incomplete combustion of the fuel, again leading to a decrease in the heating furnace’s efficiency

High oxygen content and a high air excess coefficient result in low thermal efficiency of the furnace! Conversely, it should be high, but not too low; generally, gas stoves are regulated at around 2-3%, while fuel burners are regulated at around 3-5%
