1. The brief introduction of the pellet steam boiler of the DZL series:

1. Proper design: the vertical pipe structure facilitates heating transfer and the heating efficiency meets the related national standard. The boiler furnace is designed to decrease the expansion force and enlarge the heated surface.
2. Highly pure: the dryness percent of steam capacity is above 96%.
3. Safe and reliable: the boiler is installed with multiple safety control system, including pressure, temperature,and water level. Slight pressure operation,with no backfire and flame lifting
4. Fully automatic :The automatic product control system can realize cluster control and easy operation,and only one operator is needed.
5. Highly efficient: the usage of reproducible biomass energy is of low cost, reducing operating cost by 30-60% compared with oil (gas).
6. Low-carbon: low soot, sulphur and nitrogen emission,and the carbon dioxide emission meets the standard of GB13271.

2. Application Scope:

Industrial usage: the pharmaceutical, paper making, tobacco, printing and dyeing, garment and other industries;

Civil usages: get heating, restaurant, laundry room, (hospital) disinfection, sauna, etc.;

3. Requirement for the biomass pellet fuel:

• The diameter: Φ6-8mm.
• The length: 15mm-40mm.
• The moisture: less than 45%.
• Ash percent: less than1.5%.
• Sulfur percent: less than 0.07%.
• Calorific value: more than 1500 calorific.

4. The boiler parts as following:

• Boiler proper
• Pellet burner
• Electric cabinet
• Vales and gauges
• Water pump
• Dust remover
• Induced draft fan
• Waste heat recovery
• Water softener
