Economy of gas fired high efficiency condensing boiler, the economic and technical parameters of WNS gas fired steam boiler, WNS normal pressure economizer gas fired steam boiler and WNS condensing steam boiler are compared and analyzed. By comparison, it can be seen clearly that condensing gas steam boilers can produce significant economic benefits compared with conventional gas steam boilers (including those with energy saving devices).
With the sustainable development of China’s economy, the adjustment of energy structure and the requirement of energy conservation and emission reduction, the use of natural gas will continue to increase. As the price of gas and steam rises, the economics will become clearer.
To sum up, the gas fired condensing boiler is in line with the national policy of energy conservation and emission reduction due to its high efficiency and environmental protection. Is the future gas boiler development direction. With the rapid development of China’s economy and the continuous improvement of people’s material living standards, it will be more widely used.
The main technical characteristics of the gas fired high efficiency condensing boiler:
- Boiler combustor and heating surface adopt low combustor design, heating surface adopt eccentric arrangement, that is, the furnace bile is arranged in the lowest position, which is conducive to the combustion chamber with the highest temperature buried in water, so that the safe range of boiler water level is increased;
- The boiler adopts the structure of wet back and full corrugated furnace, so that the rear tube plate of the boiler is not directly scour by the high-temperature flue gas, which improves the working conditions of the boiler and reduces the heat dissipation loss of the boiler;
- To further reduce the boiler exhaust temperature and improve boiler efficiency. There is a condenser at the end of the boiler, which has compact structure, small volume, good heat exchange effect and small smoke resistance. The condenser is designed with ND steel and can be flexibly selected according to different requirements of users. The condenser is generally suitable for industrial boilers with light diesel and gas dual fuel.
- The burner is specially designed with low excess air coefficient to ensure complete combustion and greatly reduce the generation of harmful gases
