Product introduction

DZL series biomass horizontal three return water fire tube chain grate boiler is a fast installation boiler. The boiler body is arranged longitudinally in a single drum, and a threaded pyrotechnic pipe is arranged in the drum to form a convection heating surface, and the drum and the water walls on both sides form a furnace radiation heating surface. The combustion equipment adopts light chain grate; the whole quick installation form leaves the factory. The electric control realizes the stepless speed regulation, limit parameter alarm and interlock protection.

Product Advantage:

1.An arch tube plate and a spirally corrugated tube are used to form a pot cylinder, which changes from a quasi-rigid body to a quasi-elastic body structure.

2.The lower part of the pot barrel is equipped with the ascending pipe row, which eliminates the dead water area at the bottom of the pot barrel, making the sludge less easy to deposit. The high temperature area of the pot barrel can be well cooled, preventing overfiring bulge the bottom of the the drum.

3. Under the action of centrifugal force, the dust particles in the flue gas are separated and settled on the grate surface.

4. Using high-efficiency heat transfer screw pipe, the effect of heat transfer enhancement was obtained. At the same time, the flue gas has the function of high-speed disturbance in the pipe.
