How to identify the thermal efficiency of vacuum hot water boiler

2020-04-23

Vacuum hot water boiler is hailed as a trend in the field of civil heating. It has the advantages of safety, reliability, long service life, high thermal efficiency, and low investment. It is widely used in heating and hot water supply in residential areas, commercial places, etc. The widespread use of boilers is also crucial to how to identify the thermal efficiency of vacuum hot water boilers.

The thermal efficiency of the boiler refers to the percentage of the effective heat in the heat fed by the fuel. The heat of the fuel fed into the boiler, most of which is absorbed by the heating surface of the boiler, produces water vapor. This is the effective heat used. The other part of the heat is lost. This part of heat is called heat loss. The vacuum hot water boiler runs at rated efficiency, the exhaust temperature is 185 ℃, the exhaust temperature is better than the national standard below 220 ℃, indicating that the fuel combustion heat is absorbed by the system circulating water, then the thermal efficiency is higher than the national standard (87-88%) .

In the domestic manufacturing of vacuum hot water boilers, our company is in a leading position in the country. Due to the steam-water heat exchange, the entire heat exchange coil is surrounded by negative pressure saturated steam, which is in the working state of the wet coil. Thermal efficiency is much higher than water-water heat exchange. Therefore, the volume of the vacuum hot water boiler is small, and the efficiency is high, which exemplifies the superiority for the small room of the machine room. Moreover, due to the steam-water heat exchange, the warm-up time is shorter, which saves operating costs.
