DZL series coal fired boiler is single drum water-fire tube boiler, chain grate type. Water wall tubes at left and right sides of furnace are the radiated heating area. it has two wings at furnace and screw fire tube in the drum are convection heating area. The upper drum, water wall tube and its heads are in symmetrical arrangement mode. This why furnace structure is in reasonable arrangement and high efficiency. This series boiler adopts several environmental protect measures (bag dust collector, double towers desulfurization, etc.) to meet the national emission requirement.This boiler uses the new scientific achievement, such as arch tube plate and corrugated tube, to solve the problem of tube plate flaw and water wall tube explosion, improve the heat transfer efficiency and thermal efficiency, increase the output. The boiler is wide adoptability of different fuels, such as coal, biomass fuel, wood, straw, bagasse, rice husk, coconut shell, etc.

Technical advantages
1.Wing flue can cool down smoke in high temperature tube sheet, avoid subcooled boiling, reduce boiler bottom heat load, avoid tube sheet crack, avoid drum deformation.
2.Arch tube plate can Improve tube sheet flexibility, reduce welding seam thermal stress. remove brace and avoid tube sheet crack.
3.Thread tube can enhance heat transfer,reduce drum size,improve flexibility, reduce welding seam thermal stress.

Design characteristics
Soot inertial separation device is set inside boiler and Big volume natural sedimentation chamber is set on the rear arch top. Smoke flow speeds is slow here, some particles in the smoke can be separated out because of gravity. The smoke turns fast at the head of wing flue, and many particles are separated out because of inertia. It lows original emission concentration. The ash in the rear arch can fall on the grate by ash falling hole, then be removed, which decreases secondary pollution. The boiler operates well and turns out that the original emission concentration is less than 2000mg/Nm³. Besides, with the equipped high efficiency dust collector, the boiler emission concentration satisfies national 1-class standard.
The intense radiation furnace arch can form reasonable 'A' style fire to prompt the combustion. Water cooling wall forms furnace upon the grate. It is big enough to burn the coal completely. The reasonable arch arrangement ensures flow speed. Meanwhile, the inside thread smoke tube, high efficient burning device, well-designed arches and high quality insulation materials and other characteristics ensure the boiler thermal efficiency is higher than national standard.
