Specifications

SZL series mixed burning of coal and waste boiler :
GB/T19001-200idt ISO9001:2000certified
PRC manufacturing qualificationaaAS

     SZL series mixed burning of coal and waste boiler  features: 

1. The design of double drum, assemble type, chain grate, and monolayer arrangement of the boiler room features the following advantages: compacts structure, large heating surface, safe and reliable operation, short construction period, and low installation cost ect.

2. The furnace shall employ stuff device and cyclone reburning chamber, decreasing the dust contained in the flue gas. The tail shall be equipped with gas handing equipment, which shall make the dust emission concentration to reach to the national primary standard.

3. The feeding device with rational structure shall use mechanical bond wind feeding, featuring the following advantages: uniform, reliable, and high mechanization degree.

4. The application of small roller structure and boundary grate chip to grate and other patent technology, shall improve the reliability of the operation for the boiler.

5. The sealed wind chamber and bilateral grate air register are national patent technology, and the machining cone seal structure shall improve the grate wind sensitivity.

6. The boiler shall be applied with II and III coal, combinedly burning waste produced during the production process in the paper mill, such as wheat straw slag, waste paper, sludge waste coal etc. In addition, the waste should contain high water content.
