Biomass Fuel Reed Pellet Production Line in Romania

RICHI MACHINERY

Project Background

Romania’s energy sector is in a transitional phase, with EU directives pushing for a reduction in fossil fuel dependency. The client, whose background is in agricultural logistics and supply, recognized two key factors: the vast, sustainable supply of reeds from the Danube Delta and the increasing demand for standardized solid biofuels in Central and Eastern Europe. Regular harvesting of these reeds is necessary to maintain the health of the delta’s ecosystem, but the harvested material often had no high-value application, leading to disposal issues.

The client’s vision was to create a circular economy model. By establishing this Biomass Fuel Reed Pellet Production Line in Romania, they aimed to:

• Solve an Ecological Problem: Provide a commercial outlet for harvested reeds, incentivizing sustainable management of the delta.
• Generate Renewable Energy: Produce a consistent, high-calorific-value fuel to displace coal in industrial boilers.
• Create Local Jobs: Establish a new industry in the region, creating 45 direct jobs and stimulating related logistics and service sectors.

The decision to target a 6 t/h (60,000 t/year) output was based on a detailed market analysis, indicating a strong and growing demand for industrial-grade biomass pellets that could match the scale of the available raw material.

Raw Material

The success of any biomass pellet project hinges on a secure and well-characterized raw material supply. For this Biomass Fuel Reed Pellet Production Line in Romania, the primary feedstock is common reed (Phragmites australis) sourced from managed harvests in the Danube Delta.

Romania, home to the magnificent Danube Delta, has an immense and sustainable supply of this biomass. The reeds are harvested during the dry season, when their moisture content is naturally lower. Upon delivery to the plant site, the reeds have an average moisture content of 50%. The project’s raw material yard is designed to store a buffer stock of 10,000 tonnes, allowing for continuous operation throughout the year. The inherent fibrous structure of reeds makes them an excellent raw material for pelletization, producing durable and energy-dense pellets.

Production Process and Technology

The production process for this Biomass Fuel Reed Pellet Production Line in Romania is a continuous, multi-stage system designed by RICHI’s engineers to handle the specific characteristics of reed biomass efficiently. The core technology is a dry-process, high-temperature pelletizing line, which ensures high pellet quality and optimal energy efficiency.

The process flow can be broken down into the following key stages:

1. Reception and Pre-Cleaning: Delivered reed bales are stored in the dedicated raw material yard. A grab crane is used to feed the bales into the production line.

2. Primary Size Reduction (Coarse Crushing): The reed bales are first fed into a high-capacity rotary cutter. This machine efficiently breaks apart the bales and performs an initial coarse cutting, preparing the material for finer grinding. This stage generates some dust, which is controlled by integrated dust collection systems.

3. Fine Grinding (Hammer Milling): The coarsely cut reed is then conveyed to a powerful hammer mill (F65*100). Here, it is pulverized into a fine, consistent biomass powder. This step is critical for achieving high pellet quality and durability. Two parallel hammer mill systems ensure the required throughput is met. Each mill is equipped with a dedicated baghouse dust filter to capture over 99% of the particulate matter generated.

4. Drying: The ground reed powder, with a moisture content of around 30%, is too wet for effective pelletization. It is fed into a large rotary drum dryer, heated by a dedicated biomass-fired hot air generator (using a portion of the produced pellets as fuel). The dryer reduces the moisture content to an optimal 10-15%. The hot air generator’s exhaust gases are cleaned using a wet scrubber to meet strict emission standards.

5. Pelletizing: The dried and finely ground reed powder is the primary raw material for the biomass pellet mill. This is the heart of the Biomass Fuel Reed Pellet Production Line in Romania. The material is fed into a RICHI high-capacity ring die pellet mill. Under high pressure and controlled temperature (110-120°C), the lignin within the biomass softens and acts as a natural binder, forcing the material through the die holes to form dense, solid pellets.

6. Cooling and Screening: The newly formed pellets are hot and soft. They are conveyed to a counter-flow cooler, where ambient air is used to harden and stabilize them. A vibrating screen then removes any fine particles and broken pellets, ensuring only high-quality, whole pellets proceed to packaging.

7. Packaging and Storage: The finished pellets are automatically weighed and packed into 15kg bags or one-tonne big bags using automated bagging scales. The packaged product is then palletized and moved to the finished product warehouse, ready for dispatch.

Environmental and Economic Sustainability

This Biomass Fuel Reed Pellet Production Line in Romania is a model of environmental sustainability. The project transforms a natural waste product into a clean energy source, contributing to a circular economy. Specific environmental measures include:

• Air Emissions Control: All major dust generation points (crushing, grinding, pelletizing) are equipped with high-efficiency baghouse filters. The hot air generator uses a wet scrubber, ensuring emissions of particulates, SO₂, and NOx are well below Romanian and EU environmental standards.
• Waste Minimization: Dust collected by the filters is directly recycled back into the production process. Off-spec pellets are crushed and reused as raw material, resulting in near-zero industrial waste.
• Water Management: The project has a minimal water footprint, used only for equipment cooling (in a closed-loop system) and staff facilities. No process wastewater is discharged into the environment.

Economically, the biomass pellet project has a calculated payback period of 4-5 years, driven by the stable and growing market for biomass fuels. It creates local employment and adds value to a previously underutilized natural resource.

Market Prospects for Biomass Pellets in Romania

The future for biomass pellets in Romania is exceptionally bright. The country has committed to increasing the share of renewables in its energy mix, and biomass plays a crucial role in this strategy, particularly for heating. The primary market drivers include:

• Government Policies: Support schemes and carbon reduction targets make coal-fired heating increasingly expensive and less desirable.
• Energy Security: Utilizing domestic biomass resources reduces reliance on imported fossil fuels, particularly natural gas.
• Cost Competitiveness: Reed pellets offer a stable and often lower-cost alternative for district heating companies, factories, and agricultural enterprises.

This Biomass Fuel Reed Pellet Production Line in Romania is perfectly positioned to capture a significant share of this emerging market. The client’s strategic location provides excellent access to both raw materials and key consumption centers in Romania and beyond.
