Product Introduction

Question 1-Product Description

Rice Husk Burner Design Principles and Features:

Fuel-Specific Adaptability: Engineered specifically for the physical and chemical properties of rice husks—such as their light weight, high volume, high ash content, and high silica content—ensuring stable feeding, smooth conveyance, and complete combustion.
High-Efficiency Combustion System: Typically employs suspension combustion or fluidized-bed combustion technology. By optimizing the air-fuel ratio (primary and secondary air) and furnace structure, it ensures complete combustion of rice husks at high temperatures, significantly improving combustion efficiency.
Stable Thermal Output: Equipped with automatic feeding and intelligent control systems, it enables stable control of the combustion process and thermal output, meeting the continuous heat demands of industrial production.
Ash Handling: The resulting rice husk ash (rich in silica) can be used as raw material for producing activated carbon, high-quality insulation materials, or soil conditioners, achieving full material circularity.

Remarks of 600,000 kcal Rice Husk Burner

Item	Description
Remarks	Double-layer furnace waste heat recovery system (saves over 10% energy vs. ordinary models); secondary oxygenation at the fire port enables more sufficient semi-gasification combustion (no smoke); the blanking pipe is equipped with a blower to prevent smoke backflow and backfire.

Benefits of rice husk burners

Waste-to-Energy: Converts agricultural waste (rice husks) into valuable energy, addressing the environmental issues caused by piling up or discarding husks.

Low-Cost Energy: Very low fuel costs provide a highly economical thermal energy solution for applications such as rice processing, grain drying, industrial steam boilers, and hot water supply.

Carbon-Neutral Cycle: The CO₂ released during combustion originates from photosynthesis during plant growth, resulting in no net increase in atmospheric carbon emissions and aligning with sustainable development principles.

Question 4-Application

Rice Milling Industry

Provides process heat for paddy drying and rice milling plants

Industrial Boilers

Replaces gas, oil, or coal to provide steam or thermal energy for industries

District Heating

Used for centralized heating or hot water supply in agricultural parks and grain-producing regions.

Power Generation Systems

Serves as a key component in biomass power plants, converting thermal energy into electricity.

Question 5-FAQ

Q: What is the thermal efficiency of the rice husk burner? How high a temperature can it generate?
A: The combustion efficiency of standard models typically exceeds 85%. The generated flue gas temperature can be adjusted within the range of 700°C to 1050°C, depending on the configuration and application, which is sufficient to meet most industrial drying, steam generation, and heat conversion needs.

Q: Compared to using natural gas or coal, how much can we save by using rice husks as fuel?
A: The extent of savings depends on the local prices of rice husks, natural gas, and coal. However, rice husks, as a processing by-product, typically reduce fuel costs to 30%-50% of coal costs and 10%-20% of natural gas costs. The payback period (considering equipment purchase costs) is generally 1 to 3 years, depending on your thermal energy requirements and operational scale.

Q: What is the level of automation for the rice husk burner? How many operators are required?
A: We offer configurations ranging from basic semi-automatic to fully automatic. Standard fully automatic models are equipped with:

Automatic feeding system
PLC intelligent control system (monitoring temperature, airflow, pressure, etc.)
Safety interlock protection
Under normal and stable operating conditions, only one operator is typically needed for monitoring and daily inspections.
