In the boiler market, a boiler product called “condensing” boiler is getting windy. So what are the advantages of this kind of condensing boiler? What are the advantages compared with ordinary boilers?
First, as the name suggests, the condensing boiler is a boiler that uses condensation technology. The flue gas discharged from the boiler is re-heated by the condensing device, and the sensible heat and steam condensation in the exhaust gas are fully utilized to form the latent heat released by the water droplets. The purpose of boiler thermal efficiency.
After the traditional boiler is used, the exhaust gas temperature is generally around 160~250 °C, and the water vapor in the flue gas is still overheated, and there is a large amount of unused heat. Generally speaking, the thermal efficiency of the boiler is calculated according to the low calorific value of the fuel. The heat of the latent heat of vaporization in the high calorific value of the fuel is not calculated, so the thermal efficiency of the conventional boiler can only reach about 87%~91%. The condensing boiler added with the condensing technology also recycles the heat of vaporizing latent heat in the flue gas discharged from the fuel, and reduces the exhaust gas temperature to 50-70 ° C, and the boiler thermal efficiency is also improved. If the efficiency of an ordinary boiler is generally around 93%, and the condensing furnace technology can increase it by 15%, it can reach about 108%. Such an energy-saving and environmentally friendly boiler will inevitably lead the development trend of the future boiler industry.
Taking natural gas fuel as an example, its high calorific value is about 9500kcal/m3, and the low calorific value is about 8600kcal/m3, which is about 900kcal/m3, which accounts for 11% of the low calorific value. Therefore, the choice of condensing boiler will be compared with ordinary boiler. Reduce gas operating costs by about 11%. (See details for high and low calorific value)
Second, the condensing boiler is more environmentally friendly. Compared with traditional coal-fired boilers, condensing boilers generally use clean and environmentally friendly natural gas as fuel. The exhaust gas generated by boiler operation is greatly reduced, and the emission of harmful substances such as sulfur oxides, nitrogen oxides and dust in urban air is alleviated. Environmentally friendly pioneer boiler products.
FANGKUAI Boiler has many years of experience in research and design of condensing boilers. The condensing series boilers have thermal efficiencies of over 107% and nitrogen oxide emissions of less than 30 mg/m3. They are also safe to use and have a long service life. The operation has many advantages such as low heat loss and has been widely used and used by users after being put into the market.
