It can be found that there are the following differences between vertical coal-fired hot water boiler and horizontal coal-fired hot water boiler by analyzing the structural diagram of vertical coal-fired hot water boiler:
The heat transfer of vertical coal-fired hot water boiler and horizontal coal-fired hot water boiler
The exhaust gas flow produced by the vertical coal-fired hot water boiler flows vertically to the heating surface from top to bottom, and the exhaust gas temperatu...
Heating equipment is common in daily life and production, and there are many kinds and uses. Users often have many questions when selecting boilers. Do users often come to inquire whether the boiler is the same as the direct-fired unit? What's the difference?
Gas boiler takes natural gas, fuel oil, etc. as fuel, and releases heat energy through combustion, which is transmitted to the medium in the boiler, so that the temperature of the medium increases. After rising to a certain tempera...
As an efficient and clean fuel, biogas is attracting more and more attention. As a professional manufacturer of biogas-fired boilers, ZOZEN Boiler has overcome technical difficulties and introduced a new type of biogas-fired boiler, which not only has sufficient output and high thermal efficiency, but also saves a large amount of fuel costs for enterprises and more effectively promotes the development of circular economy. Many users say that the working principle of biogas burning boiler is not ...
The outlet temperature of gas boiler is related to the rated working pressure, such as the outlet temperature of 95℃ at the rated working pressure of 0.7MPA and 115℃ at the rated working pressure of 1.0MPA. In daily use, it is a common problem that the outlet temperature of gas-fired boiler cannot be raised.
After summary, the reasons why the outlet water temperature of gas boiler can't be raised are as follows:
1. The set temperature is too low.
2. Whether the actual temperature is c...
Condensing boiler and non-condensing boiler are two main types of gas-fired boilers on the market at present. A correct understanding of the difference between condensing boiler and non-condensing boiler can help you choose a reasonable type. Before introducing the difference between them, it is necessary to introduce the principles of condensing boiler and non-condensing boiler.
Introduction of working principle of non-condensing boiler
Non-condensing boiler is a kind of heat energy c...
With the increasing awareness of energy conservation and environmental protection, gas-fired boilers have become the necessary heating equipment for most enterprises. So the question is, what kind of gas does the gas boiler burn?
1. natural gas
Because of its low sulfur content and high calorific value, natural gas is a clean energy source. When choosing what gas to burn in gas-fired boilers, users generally choose it. Natural gas is a general name of hydrocarbon-based mixed gas existing in un...
Boiler heating is the main way of central heating in shopping malls, enterprises and residential areas. Many enterprises should consider the heating efficiency and heating area of boilers when choosing and using them, which has a certain relationship with the boiler model and capacity. As a professional hot water boiler manufacturer, ZOZEN Boiler takes the heating area of 5-ton boiler as an example to help users better understand the selection of heating boilers.
Calculate the heating area of a...
