　 SZL Series biomass steam boiler and hot water boiler features

　　The thermal efficiency of each type of boiler is>82%,which is higher than the national standard.

　　After simplifying the water circulation circuit,the water circulation flow resistance is reduced and the flow velocity in the riser is increased;For hot water boilers,the return water ejection device is installed on the left and right water-cooled walls with large water circulation resistance.

　　Improved the reliability of the water cycle and ensured the safe and stable operation of the boiler.

　　Arrange sufficient heating surface so that the heat emitted by the fuel combustion can be fully absorbed by the heating surface and transferred to the working medium.The exhaust temperature is lower than 160℃.。

　　Reasonably arrange the front and rear arches,while increasing the furnace temperature,strengthen the disturbance of the flue gas in the high temperature region,and reduce the chemical incomplete combustion loss and fly ash loss。

　　Use large grate or scale-type grate,and ensure that there is sufficient effective area of the grate.While improving the reliability of grate operation,ensure that the fuel is fully burned。

　　Adopt double-side air inlet,separate air chamber,separate adjustment,stable combustion and reliable operation.

　　A smoke and dust inertia separation device is installed at the furnace outlet to reduce the original dust concentration of the boiler to less than 1800mg/Nm³.In conjunction with a high-efficiency multi-tube dust collector and a bag dust collector,the boiler flue gas emissions meet the national first-class area requirements.
