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...
Nowadays, with the strong support of government policies, boilers with high energy consumption and high pollution are being eliminated, which further promotes the increase of demand for energy-saving hot water boilers. I believe that when purchasing boilers, many users will encounter the problem of which manufacturer of energy-saving hot water boilers has high cost performance.
Boiler combustion efficiency
Whether the combustion of energy-saving hot water boiler is sufficient can b...
100-ton gas-fired hot water boiler refers to the gas-fired hot water boiler with rated heat supply of 70MW. 100-ton gas-fired hot water boiler is a large boiler, which is often used for central heating in cities or park heating. So what are the performance parameters of 100t gas-fired hot water boiler?

Economizer
Increase the heat exchange area of the boiler economizer. For example, adopting the economizer whose actual internal area is 1-2 times larger than the ordinary can effectively reduce the flow rate of flue gas, improve the heat exchange efficiency and lower the exhaust gas temperature.
Air preheater
An air preheater is installed with the connected pipe behind the economizer, which can effectively increase the air temperature for supporting the combustion, improve the fuel ignition ...
As we all know, the transportation cost is generally related to the weight of the boiler, so how much does a 4-ton boiler weigh? How much steel does it contain? According to the fuel, 4-ton boilers are divided into 4-ton gas-fired boilers and 4-ton coal-fired and biomass-fired boilers. The amount of steel used for small-scale coal-fired and biomass-fired boilers is generally 5-7 times of the boiler output (excluding the front and rear arches), and about 25 tons for 4-ton boilers.
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...
What is a hot water boiler? Hot water boiler is a boiler that produces hot water. It refers to a kind of thermal equipment that uses the thermal energy released by fuel combustion or other thermal energy (such as electric energy, solar energy, etc.) to heat water to the rated temperature. Hot water boiler is widely used in all aspects of heating.
In the process of hot water boiler boosting, the essence of controlling the boosting speed is to control the heating speed, which requires that the te...
There are many valves commonly used in atmospheric gas-fired boilers, including gate valves and stop valves of main steam valves, water supply valves, check valves, exhaust valves, etc.
When the water pump is turned on, the pressure signal is transmitted to the on-off valve of the atmospheric gas-fired boiler through the pressure pipe, the valve is opened, and the water circulation is carried out. When the water pump stops, the pressure drops, and the on-off valve is closed slowly to av...
