The difference between gas-fired hot stove and gas-fired boiler lies in the word vacuum. It uses water to produce steam at low temperature boiling under low pressure. The principle of heat output through steam-water condensation heat transfer works. Its service life is longer than that of gas-fired boiler. How long is the service life of gas-fired hot stove? Referring to the use of gas-fired hot stove? Life needs to know the structure of gas-fired hot-blast stove, the heat medium (furnace water) in the furnace, in the whole process of boiler operation, does not enter, exit, increase or decrease, only enclosed in the vacuum chamber of the boiler, and transfers heat between the heat transfer tube and the heat exchanger of the boiler. The heat medium in the furnace is pure deoxidized water without corrosion and scale. 因此从进入到燃气热风炉的水质可以看出，燃气热风炉不易发生腐蚀，因此使用寿命也会大大增强，据山东华源锅炉有限公司介绍，山东华源锅炉有限公司生产的燃气热风炉寿命长达20多年甚至更长。
Therefore, from the water quality into the gas hot-blast stove, we can see that the gas hot-blast stove is not easy to corrode, so its service life will be greatly enhanced. According to Shandong Huayuan Boiler Co., Ltd., the gas hot-blast stove produced by Shandong Huayuan Boiler Co., Ltd. has a service life of more than 20 years or even longer.
At the same time, heat exchange is carried out in the main body of the gas-fired hot-blast stove. The efficiency of the whole machine is over 91%. Hot water at 70-80 C can be provided within 2-3 minutes after start-up, which greatly shortens the preheating period and reduces energy waste. The service life of the gas-fired hot-blast stove is 2-3 times that of other types of boilers.
