The gas-fired steam boiler is a star product of Zhengzhou Fangkui Boiler Factory. As for why it sells very well, it is mainly related to the performance advantages of the boiler itself. However, many users still have some doubts when operating this type of boiler. Today, Zhengzhou Fangkui Boiler Company will come to answer them one by one.
What is the role of circulating water in gas steam boilers?
In a boiler such as a gas-fired steam boiler, the purpose of circulating water inside is to allow the heating surface of the boiler to be evenly heated, so that the heat energy can be effectively transferred to the heat medium, and then the boiler can generate steam.
Are there any requirements for the feed water temperature of gas steam boilers?
Regarding the feed water temperature of gas-fired steam boilers, there are currently no regulations in this regard, which are generally determined based on actual conditions and deaeration conditions.
What is the difference between two-pass and three-pass in gas steam boilers?
In the gas-fired steam boiler, the second return stroke means that the boiler is not provided with a second return stroke smoke tube, etc., and the flue gas in the furnace is from front to back. The three-pass means that the flue gas is discharged from the boiler after the heat is transferred from the furnace, the two-pass smoke pipe and the three-pass. This is the difference between them.
Is there a difference between the theoretical and practical gas consumption of a 0.3-ton gas-fired steam boiler per hour?
A 0.3 ton gas steam boiler is a 0.3 ton gas steam boiler. The theoretical value of gas consumption per hour is about 21 cubic meters, but in actual operation, it will be lower than this value. As for the specific data, it depends on the actual Situation.
