The flue gas temperature can directly reflect the operating status of a gas-fired hot water boiler. As for why this is so, Zhengzhou Fangkui Boiler Company gives a clear answer.
Many users will have such a doubt, whether there are upper and lower limits on the exhaust gas temperature of gas hot water boilers?
In this regard, from the current perspective, there are no regulations in this regard, but there are still some requirements in the entire boiler industry. Because the flue gas temperature will directly or indirectly affect the operating efficiency of the boiler, resulting in a situation of energy-saving operation or non-energy-saving operation. We need to pay attention to that there is an inverse relationship between the flue gas temperature and efficiency of the boiler. The higher the boiler exhaust temperature, the lower the efficiency, and the less energy-saving.
What methods can be used to combine gas hot water boiler with solar energy system?
If the gas-fired hot water boiler is combined with the solar energy system, the main ways to combine them are the following.
Method 1: The control cabinet in the solar system controls the start and stop of the circulating pump according to the water temperature and temperature, and there is a water flow switch on the boiler, which starts the boiler when the water flows and performs circulating heating.
Method 2: Install a temperature probe in the water tank. When the temperature is lower than the set value, turn on the circulating pump and the boiler for circulating heating.
Method 3: If the boiler is a direct-heating structure, the water in the water tank can be directly used by heating the boiler once.
Can gas condensers be used in gas-fired hot water boilers?
Flue gas condensers can be used in gas hot water boilers, but pay attention to the installation location, which should be directly connected to the return water pipeline. In fact, it can also be considered that an energy-saving device is added to the boiler, so as to improve the inlet temperature and thermal efficiency of the boiler.
