Advantages of Gas Steam Generators for Heating

Condensing gas steam generators are commonly used as a heat source for air conditioning or for supplying domestic hot water, and are ideally suited for use as a low-temperature heating system for swimming pools, underfloor heating, and other applications where high thermal efficiencies are desirable. Generally speaking, condensing steam generators are used in wall mounted steam generators and floor standing steam generators, which are usually used in domestic and commercial heating systems, but can also be used in several units for larger heating systems. Condensing steam generator in the heating industry has the following advantages:

　　1, green

　　Than the coal-fired steam generator, ordinary gas steam generator without the dust pollution, sulfur dioxide emissions are greatly reduced, which becomes really green. But in recent years the hazy weather in various regions, and its environmental health awareness of the enhancement of low nitrogen regulations more imperative.

　　2, energy efficient

　　Ordinary gas steam generator thermal efficiency of 90% or so, high enough to reach 95% or so of the level, while the condensing steam generator thermal efficiency is greater than 100%, condensing steam generator in the full load of high thermal efficiency can reach 108.9%.

　　Steam generator key heat loss for the exhaust heat loss, ordinary gas steam generator exhaust temperature of not less than 110 ℃, the heat in the flue gas will not be used is obviously a waste. Therefore, the condensing steam generator by reducing the steam generator exhaust temperature of 55 ℃ or so, not only absorbed the flue gas in the sensible heat, in addition to absorbing the gas combustion products of the latent heat of vaporization of water, resulting in condensing steam generator than the average gas steam generator thermal efficiency increased by about 15%.
