Biomass Boiler | Use ricehusk olivehusk
Fuel: ricehusk, coconut shell, palm shell, cashewnut shell, peanut shell, sunflower seeds shell, sawdust, wood, coal...
> Product: Ricehusk Stoker Boiler
DZL serie biomass rice husk fired boiler, with automatic feeding chain grate combustion stoker.
Design features: Three pass sturcture help improve heat efficiency. Boiler inner use water tubes and fire tubes for heat conduction. Large combustion space in furnace with specifical husk burning furnace design, ensures higher burning efficiency. Automatic husk feeding system, saving labor work and time cost.
Husk Stoker Boiler Features
1. Large stove space for ricehusk burning. In order to prevent the rice husks from being blown out of the furnace before they burn out, increase the distance between the front and rear arches.
2. Optimal boiler water pipes thickness and surface anti-wear processing, increasing the heating area and strength heat transfer efficiency, make full use of fuel heat power and produce more steam, make the boiler output more stable.
3. Reasonable control for rice husk thickness and grate speed when ricehusk burning in stove. The preferable amount of forced air and induced air aim to let the rice husk burning in a semi-suspended state on the fire grate.
Product: Biomass Husk Burner Boiler
Yuanda fire tube biomass boiler, with automatic biomass burner combustion device. Consiste of Fire Tube Boiler and Biomass Burner.
2. Work principle: It use husk burner device burning biomass supplying heating source, then high-temperature flue gas into fire tube boiler, three pass structure for heating water, help improve thermal efficiency.
Husk Burner Boiler Advantages
1. Energy-saving: Renewable biomass pellet fuel is used as energy source, the using cost is low.
2. Low-carbon environmental protection: low smoke, sulfur and nitrogen emissions, and nearly zero carbon dioxide emissions.
3. High thermal efficiency: semi-gasified suspension combustion with tangent a swirl flow air distribution design, low temperature staged combustion, burnout rate of more than 98%, and furnace temperature of more than 1200 ℃.
4. Simple operation: easy installation, automatic feeding, simple operation, less workload, large silo capacity (larger capacity silo can be customized). The feeding can be run for 3-12 hours at a time, only need to fill the bin in time, only one person on duty is OK.
Boiler Features

Chain Grate / Reciprocating Grate
Fitted with either a chain grate or reciprocating grate, suitable for various types of solid fuels such as coal, biomass, or wood, ensuring full combustion and stable performance.
Water Softener
A complete water treatment system is included to remove hardness and prevent scale formation, protecting the boiler and improving efficiency.
Security guaranteed & Automation
Multiple safety and monitoring devices — pressure gauge, water level gauge, temperature sensor, and automatic safety protection system — ensure safe and reliable operation.
Economizer for Energy Saving
Equipped with a high-efficiency economizer to utilize waste heat from flue gas, reduce fuel consumption, and improve overall thermal efficiency.Technical Parameter
