The structure & characteristic of DZL series travelling grate stoker steam/hot water boiler

The“DZL” series travelling grate stoker coal fired steam/hot water boiler ,is adopted 3-pass horizontal water-fire tube packagedstructure.it’s natural circulation boiler, uses secondary air ,segmental and dependent air supply ,light travelling grate and thicker fire grate segment。It’ advantages as follow:.

1、     Uses the thread smoke tube instead of  plain tube, the heat transfer effect

2、     Thedistinctivesecondary air design eliminates the dead angle of combustion area, and makes combustion more plenitudinous

3、     rationalair distribution and infinitely variablespeedtransmission, travelling grate can work at discretional speed in setting range,

4、     Thicken fire grate segment is high-intencitive and long maintenance intervals and it’s usefullifeis more longer,

5、     All-welded tube plate no relaxations and leakage.

6、     Big diameter water wall, good circulation and lower need to water quality.

7、     Light boiler settings is elegant appearant and economical for carriage.

8、     mechanizationof running , lower people’s working intensity ,labor-saving machinery

9、     Stainless steel water pump, failure rate is lower and the ues life is longer.

10、  compactin frame、small floor space and low investment

11、  package boiler makes installation is more convenient and the equipment be run into operation quickly
