class a waste heat recovery heating boiler
New class a waste heat recovery heating boiler inspection work is needed by the boiler and pressure vessel safety inspection department, new boiler through its approval, supervision, and related performance tests. After testing by the boiler manufacturing unit can be formally delivered to the use of units.
One bright spot: small footprint design Integrated economizer, air preheater and integrated body design, saving space. Highlights II: advanced cooling technology of low temperature exhaust gas adopts a new environmentally friendly energy efficient technology Ultraten wings tube, the flue gas heat recovery efficiency. Wings built finned tubes, the cooling water does not flow outside the tube fouling; tearing groove design fin heat transfer area is increased 5-fold, sufficiently absorb latent heat of vaporization in the flue gas, a high heat recovery rate; silicon alloy material, corrosion resistance and long life. Highlight three: original elliptical smoke tube air preheater to reduce operating costs oblong stainless steel tube 304, a large contact surface wind resistance, the higher the heat exchange system, improve the supply air temperature, significantly reduce operating costs; corrosion-resistant stainless steel tube 304 high, high voltage resistance to high strength and durability. Highlight four: PLC intelligent control high degree of automation all Chinese color touch screen, real-time dynamic display class a waste heat recovery heating boiler operating conditions; multi-level pop-up menu, simple man-machine interaction; cloud big data services 3.0 support to ensure the safe operation of the boiler.
FGR refers to flue gas recirculation techniques, by using external flue gas recirculation and the inner loop is provided, withdrawing part of flue mixed with the combustion air, and then into the furnace through a burner, not directly involved in the combustion, by reducing the flame temperature reached reducing combustion temperature and oxygen concentration effects, thereby achieving the purpose of reducing NOx generation. Second, a low nitrogen higher thermal efficiency of the class a waste heat recovery heating boiler
4, condensing or non-condensing?
When designing the heating system return temperature is less than or equal to 50 ℃, using suitable condensing boilers.
