Low CO2 Low Nox Condensing Boiler
- Since developed in 1952 in UK and Germany, Flue tube smoke tube boiler is the most used one in hotels, hospitals, apartments, resorts, factories, and ships around the world for supplying steam for air conditioning/heating. Dae Yeol boiler attached the air preheater and economizer to the flue tube smoke tube type gas combustion boiler, and developed the ultra-high-efficiency low-CO2 low-NOx inverter condensing boiler capable of responding quickly to load variation with inverter blower and automatic continuous feed water pump. It has been received good product certification from Public Procurement Service on April 29, 2009.
- Developed in the early 1980s in Japan, once through boiler is a small boiler with heat transfer area smaller than 10㎥ area, evaporation amount under 1.5t/h It is mainly used in small businesses, and can be used with no license, no inspection. Recently, once through boiler with the capacity of 2~3t/h, and with thousands of Fins attached to the water tube. There are many cases that more than ten once through boilers with the capacity of 2~3t/h are installed under the principle to provide steam only when necessary, while only 2 or 3 condensing boilers with the capacity of 10~15t/h boiler is adequate. There, once through boilers cannot appropriately respond to load variation and cause a lot of problems in efficiency, failure (warranty service), product life, noise, and electric usage, and users get huge disadvantages.
