�ZBG DZL double-wind-gas-dust series boiler is independently by our company as

the fourth generation horizontal water tube and fire tube package

chain grate boiler. We have patent rights to this product, and DZL series has won

the State Ministry of Electrical and Mechanical Quality Award, the

provincial quality products, provincial and municipal outstanding new product

awards, provincial and municipal scientific and technological progress

awards. It is the State Electrical and Mechanical Energy Products Promotion

Project. DZL series boiler is equipped with fast, time-saving, compact

structure, small footprint, etc., with high reliability, high thermal efficiency and

strong overload capacity. The large-size components (mainly on the body

and the lower base) has been assembled in the factory, when they are installed,

just complete the interface and auxiliary and pipeline system. DZL series

adopts light chain belt with a high degree of automation, with dust removal

equipment, lessenvironmental pollution, with a good comprehensive

economic and technical indicators, the product is well praised by the majority of

consumers

Capacity: 2-10 t/hDesign thermal efficiency: 76-80%Applicable fuel: bituminous coal, anthracite, rice husk, straw, sawdust, bagasse and other biomass fuels

Application: central heating, district heating and industrial steam

Product introductionProduct introduction

SINCE���1945SINCE���1945

By adopting the water-cooling system in packaged boilers which is usually used in

power plant boilers, the boiler can achieve large heat transfer area, high heat

transfer efficiency, low heat loss, good air tightness, and no distortion or dust

leakage of the brickwork. because of direct heating the down side of the drum.

Advanced design, perfect performance1

The structure 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.

Wide variety of fuel2

a. There is push-pull type damper ash removal device. The damper adopts

finish machining cast iron seal structure, thus the secondary combustion distortion

and air leaking in the grate is effectively prevented.

b. The double-wind-gas dust design makes the flue gas smoothly enter the front

smoke box and the temperature of the front tube plate is the same and lower

than 600 ℃,�It can avoid tube plate crack caused by the DZL chain grate coal

fired boiler.

c. Exclusive configuration from the drum center line 750mm assembly wall wall

tube, completely solve the drum and the box heat up cold shrinkage caused by

the drawbacks of the weld.

Reasonable structure and safe operation3
