Introduction

Rice husk fired boiler uses rice husk as fuel, which converts agricultural waste of rice husk into energy. It used for generating steam, hot water and power generation. Rice husk is waste during rice process, if throw or direct incineration will cause environmental pollution and resource waste. Using rice husk as boiler fuel realizes the reuse of waste. It also reduces the dependence on traditional fossil fuels. This has significant environmental protection value. It also brings energy-saving benefits.

Principle and Type of Rice Husk Fired Boiler

Combustion principle: Rice husk combusts in the furnace, need to First, it goes through four stages: drying, ignition, combustion, and burnout. The low density and high ash content characteristics of rice husk make it necessary to adopt special combustion technologies during the combustion process to ensure combustion efficiency and stability.

Common types

Rice husk steam boiler: It mainly used for generating steam, widely used for steam supply in industrial production. Such as food processing, textile, and other fields.

Rice husk hot water boiler: It mainly used for providing hot water, suitable for central heating, bathing and other sites.

Rice husk power generation boiler: Through CFB technology, make rice husk combusts completely generating high-temperature and high-pressure steam, driving steam turbine generator to power generation.

The Advantages of Rice Husk Fired Boiler

Energy-saving and environmental protection: The use of rice husk fired boiler reduce straw burning, low harmful gas emission, such as carbon dioxide and carbon sulfur. It has a positive effect on improving air quality and alleviate the greenhouse effect.

Low fuel costs: Rice husk is a kind of agricultural waste with wide source and low cost, which can reduce fuel cost and improve economical benefits.

High adaptability: Rice husk fired boiler not only combust rice husk but also other biomass fuel, such as wood chips, straw.

Policy support: Rice husk fired boiler as a clean energy equipment, comply with policy and It can enjoy relevant preferential policies, such as subsidies and tax incentives, which further reduces the investment cost of enterprises.

Applications Scenarios of Rice Husk Fired Boiler

Rice processing plants and grain storage and processing: During rice processing. It needs large amounts of steam to processes such as drying and steaming. Rice husk fired boiler can use local materials, utilizing rice husk generated during processing. That can provide stable steam for plants and reduce production cost.

Food and drink industry: During the processes of food and beverages. Such as sterilizations of beverages and cooking of food both need a large amount of steam or water. Rice husk fired boiler can provide clean and stable energy for enterprises, meeting production and environmental protection and hygiene requirements.

Biomass power generation: Rice husk power generation boiler is an important element of biomass power generation plant. Through rice husk combustion to generation steam , drive steam turbine generator to generate power, converting chemical of rice husk into electric energy.

Efficiency and Operating Cost of Rice Husk Fired Boiler

The thermal efficiency of rice husk fired boiler is 75%-90%, specific efficiency depends on design of boiler, combustion technology, operating maintenance and other factors. Advanced combustion technology and good operation maintenance can improve the thermal efficiency of boilers, reducing energy consumption.

Advice for Price and Choosing Type of Rice Husk Fired Boiler

Factors that affect price

Tonnage: The larger the tonnage of the boiler, the higher the price. The tonnage determines the steam production capacity of the boiler, meeting the needs of enterprises of different scales.

Pressure: The higher working pressure of the boiler, the higher the requirements for materials or manufacture process of the equipment, the price will increase accordingly.

Configuration: Different combustion equipment and control system will cause different prices.

How to choose a proper type

According to field needs: Different industries have various requirements for the needs amount of steam or hot water, temperature and pressure, the appropriate rice husk fired boiler model should be selected according to the needs of specific industries.

According to the steam quantity: Calculate the required steam quantity based on the production scale of the enterprise and the steam demand of the steam – using equipment, and select a rice husk fired boiler with an appropriate tonnage to ensure the operating efficiency and economy of the boiler. At the same time, the standby coefficient of the boiler also needs to be considered to cope with unexpected situations during the production process.

Actual price depends on boiler design (grate type, pressure level, dust removal system), auxiliary equipment, installation, and regional standards.

Market Prospect of Rice Husk Fired Boiler

Traditional coal-fired boilers are under the pressure of being phased out due to their serious environmental pollution. As a clean energy device, the rice husk fired boiler has good substitution potential. In some rice-growing areas and rice processing enterprises, the rice husk fired boiler can obtain raw materials locally. Using rice husks as fuel to replace traditional coal – fired boilers, achieving clean and sustainable energy utilization, and reducing the environmental protection costs and energy costs of enterprises.

Conclusion

As the world shifts towards cleaner energy, rice husk fired boilers present a promising market opportunity, particularly in rice – growing regions. They contribute to sustainable development by optimizing energy use and reducing environmental impact.For more information on rice husk fired boilers, contact us.
