DZH Firewood Coal Biomass Fired Steam Boiler

Product Specification

DZH Firewood Coal Biomass Fired Industrial Steam Boiler for Wine Factory

1. Brief Introduction

The DZH series coal fired boiler is water-fire tube boiler, which is a new eco-friendly and energy-saving product. the steam boiler can be used for industrial processes of pasteurization, distillation, sterilization, disinfect, extraction, drying, and curing, etc. This steam boiler can widely used for textile factory, rice mill, food industry, beer and brewery factory, oil processing, cosmetic, etc.

• Model: DZL series
• Steam Capacity: 1 ton, 2 ton, 4 ton, 6 ton, 10 ton, 15 ton, 20 ton, 30 ton, 40 ton per hour
• Pressure:0.7 Mpa, 1.0Mpa(10bar),1.25Mpa(13bar),1.6Mpa(16bar),2.5Mpa(25bar)
• Steam temperature:184 °c,194°c, 204°c, 226°c, 450°c
• Structure: horizontal water-fire tube, single drum
• Type: chain grate stoker automatic feeding fuel and removing dregs type

2. Features and advantages:

1.The boiler has big drum and have big enough space for water. Compared with the SZL series, the DZL boiler is more adaptable to poor water quality. Moreover , when the boiler scaled, it is convenient for maintenance.

2. Adopting convex tube plate, prevent tube plate cracking and simplify the structure of canceling the tension bar.

3. The Wing-shape flue arrangement, the flue gas is three pass, reduce the smoke temperature of high temperature area tube plate, thereby preventing the cracking of tube plate and Boiler tube explosion.

4. Adopting threaded smoke-tube technology, strengthen heat transfer, reduce the number of pipes and the size of boiler shell; reduce the thermal stress at the end of the pipe, and prevent cracking of the tube plate. At the same time, due to the self-cleaning ability of the flue gas in he threaded pipe, avoid the accumulation of dust in the tube.

Benefits of thread smoke tube on boilers:

1. Increase the boiler heat transfer efficiency

2. Reduce the number of tubes and reduce the size of the boiler shell

3. Reduce the thermal stress at the tube end to prevent cracking of tube sheet.

4. Save steel and manufacturing costs

Why the thread smoke tube can increase the heat exchange efficiency of the boiler?

the number of collisions between the flue gas and the pipe determines the heat exchange effect of the boiler. The thread pipe is processed to be unevenness to enhance the number of collisions. The higher the number of collisions, the better the heat transfer effect.
