Industrial DZL series of traveling grate boilers
Industrial DZL series of traveling grate boilers
Type:natural circulation
Structure:water/fire tube
Style:a horizontal type with single drum
Type:natural circulation
Structure:water/fire tube
Style:a horizontal type with single drum
DZL Series Packaged Traveling Grate Boiler could easily burn coal and shaped biomass fuel or mixture of coal and biomass fuel with its economizer in the rear that discharges the slag which could be used as fertile to agriculture.
The features of DZL Series Packaged Traveling Grate Boiler are as follows:
1.Some of the rising tubes on two sides of steam header go up to the furnace, then go to down side of drum, together with the mason work insulation heating surface there, all these form the DZL Series Packaged Traveling Grate Boiler top heating surface. By adopting of this novel furnace structure, we tackle the deficiency of "bulge" which is happen because of direct heating the down side of the drum.

By adopting of this novel furnace structure, we tackle the deficiency of "bulge" which is happen because of direct heating the down side of the drum.
2.By adopting of double wings gas ducts, the fuel gas can go into the front gas tank easily, so the temperature of different front plates can be same. In this way, it can avoid the crackles happening in the plates.
3.Spiral tubes are installed in the drums, which can strengthen the heating transferring efficiency, at the same time, spiral tubes have the ability of dust removal, which can avoid the dust stratification in the tubes.
4.Both of the front and the back arches of the 10t/h series boilers adopt mason work of water cool tubes wall structure, which can form permanent arches.
5.DZL Series Packaged Traveling Grate Boilerstructures of the arches adopt the latest research product, second prize of advance awarded by Xi'an Jiaotong University. The back arch is low and long and the part near the exit is inverse inclined type, while the front arch is 45°inclined type, they together form a downside "a" flame structure, which makes the lean coal combustion easier and it can adjust itself to a wide range of coal types.
6.The side seal of DZL Series Packaged Traveling Grate Boiler is advanced and reasonable, which can avoid the deficiency of side seal jammed grate and the deficiency of side seal burned out. The boilers less than 4t/h adopt side seal cooling and angle iron reinforce plates, and more than 6t/h boiler adopt full touch side seal and down seal structure.
7.There are separate adjustable wind chambers. Wind is feed from two sides. It adopts new type crank screw wind adjustment structure, so that the wind adjustment and ventilation cross section proportion is 100%, which can ensure the easy wind adjustment and make it symmetrically.
8.There is push-pull damper dust removal equipment. The damper adopt finish machining cast iron seal structure, thus the secondary combustion distortion and air leaking in the grate is effectively prevented.
