The circulating water flow rate is an important parameter for the efficient operation of hot water boilers. The calculation formula for the circulating water flow rate in hot water boilers is based on several factors, including the heat load, temperature difference, and flow rate. The formula can be complex and may vary depending on the specific boiler and application.
At ZOZEN Boiler, we understand the importance of reliable and efficient hot water boilers for your heating needs. Our W...
As a clean fuel, natural gas has much lower sulfur content and nitrogen content than coal, and there is no ash in the fuel, and the flue gas produced after combustion is almost smoke-free. Therefore, a nationwide upsurge of coal to gas has been set off.
However, there are some problems in the process of gas boiler operation, among which the hardness, harm and treatment of gas boiler flue gas condensate are prominent.
When the boiler flue gas temperature is lower than the dew po...
The fuel of gas boiler is mainly natural gas, petroleum gas, gas, etc. The air energy water heater is powered by electric power and air energy to maintain the operation of the machine.
Because gas-fired hot water heating boiler is used for central heating, after the boiler is ignited, it needs to go through a series of processes such as furnace heating, low-temperature operation, heat exchange and so on, to gradually heat up the central heating. After ignition of gas-fired hot water heating boiler, furnace heating is a necessary preparation work at the initial stage of heating every year, and this process takes about 3-5 days to complete.
It depends on the system of the gas boiler, the boiler water temperature at 60-90, 90-150 and 70-130 can achieve better energy-saving effect.
Energy-saving devices such as condensers are added to ZOZEN gas-fired hot water boiler. The waste heat is used to increase the water temperature of the gas-fired boiler. The rated inlet temperature is 70℃, and the exhaust gas temperature is reduced, so that the thermal efficiency of the boiler is increased to over 98%.
The principle of boiler economizer is that the flue gas from the boiler tail enters the boiler economizer, and the water in the boiler economizer absorbs the temperature in the flue gas through the finned tube and then returns to the boiler, which is equivalent to raising the boiler feed water temperature and reducing the energy consumption when the boiler output is certain.
Boiler economizer is generally installed at the tail of boiler flue. Due to the different principles and boiler equipment...
(1) The boiler and all auxiliary equipment are installed, and all tests such as ball passing test, hydrostatic test and air tightness test are qualified.

(3) The fuel and water supply are guaranteed, the steam, water and flue gas piping system are normal, and the connection unrelated to the boiler to ...
Among the commonly used steam boilers, those under the pressure of 3.825 MPa are called medium pressure steam boilers, and those under the pressure from 9.8 MPa to 13 MPa are called high pressure steam boilers. Different boiler pressures have different requirements for water quality. Generally, medium and low pressure steam boilers need to supplement softened water, and softened alkali-free water, while high pressure boilers need desalted water. The different water qualities require different corresponding treatment equipment.
