What is the difference between a condensing boiler and a common boiler?

What is the difference between a condensing boiler and a common boiler?

What is a condensing boiler? What is the difference between it and ordinary boilers? Today, we will take you to know the elite of this boiler - the condensing boiler, two minutes let you understand the difference between the condensing boiler and the ordinary boiler.

First, what is a condensing boiler
       The furnace in the furnace is a boiler that uses condensation technology to increase the thermal efficiency of the boiler. The condensing technology means that the condensing waste heat recovery device inside the boiler absorbs the sensible heat and latent heat released by the fuel combustion. The sensible heat is mainly the high-temperature flue gas generated by the combustion of the boiler, and the latent heat is mainly the heat released by the condensation of water vapor. Don't underestimate this part of the heat. Compared with ordinary boilers, the thermal efficiency of the condensing boiler can be 15%-25% higher.

Second, the difference in thermal efficiency
       The front also briefly mentions that the thermal efficiency of the condensing boiler is higher than that of the ordinary boiler, let us talk about the thermal efficiency. Why focus on thermal efficiency, is thermal efficiency so important? Of course important! The thermal efficiency of a boiler directly determines the energy consumption of this boiler. In other words, the thermal efficiency is related to the money in your pocket!
       First of all, the thermal efficiency of ordinary boilers can only reach 85%-91%, while the thermal efficiency of condensing boilers is generally higher than 100%. The thermal efficiency of condensing boilers produced by Fangkuang boiler manufacturers can reach 108%. This extra 10%-20% comes from the use of condensation technology to give full play to the sensible heat and latent heat of boiler operation. The temperature of the flue gas discharged from the ordinary boiler is very high, and the water vapor generated during the combustion of the fuel is discharged from the pipe with the flue gas, and a large part of the heat is lost. The condensing furnace recovers this part of the heat and reuses the return water of the heating and heating system to improve the thermal efficiency of the boiler by reducing the exhaust gas temperature. Under the same amount of gas, the lower the return water of the heating system, the more heat recovered by the condensing furnace, the higher the thermal efficiency of the boiler.

Third, the difference between the scale treatment
       Condensing boilers are less prone to fouling than ordinary boilers. In order to improve the heat exchange efficiency of the furnace, many boiler manufacturers use very thin heat exchangers and water pipelines, and the water quality is hard, and the pipeline is easy to form scale. Scale condensation is likely to cause pipeline blockage and damage to the equipment, which indirectly increases the maintenance cost of the boiler. The condensing furnace adopts premixed combustion technology, which is a large pipeline waterway system. The waterway is not easy to structure, so the condensing boiler has low requirements on water quality.

Fourth, the difference in environmental protection
       Condensing boilers are more environmentally friendly than ordinary boilers. When the gas is burned in the furnace, it produces a large amount of carbon dioxide, nitrogen monoxide and a little sulfur dioxide. The substances produced by these combustions will be destroyed by the air environment when the smoke is emitted to the atmosphere. The greenhouse effect and acid rain are relatively intuitive. While the condensing boiler condenses the water vapor in the flue gas, the amount of harmful substances in the flue gas is also reduced. From the perspective of environmental protection, condensing boilers are more worthy of promotion than ordinary boilers.

Fifth, the difference between price and service life
       In comparison, condensing boilers have so many benefits, the price must be higher than ordinary boilers. After all, the condensing boiler is also an elite that combines technology and quality. However, the price is definitely expensive. It is more expensive than the environmental protection and energy saving. The service life of the condensing furnace is higher than that of the ordinary boiler, and the cost performance is higher.
