5L-80 biomass pellet furnace for medium-scale grain drying projects
Model: 5L-80

5L-80 Biomass Pellet Furnace

The 5L-80 biomass pellet furnace is a higher-capacity 5L-series hot-air unit for customers who need stronger heating capacity for grain drying and related applications. In the current source set, it is presented as a mature match for Tongtai’s 55-ton newly developed batch dryer and as a practical indirect-heating biomass furnace for medium-scale projects.

Advantages

Why the 5L-80 is one of the stronger confirmed models in the 5L family.

Higher-capacity matched solution

The 5L-80 is documented as the furnace matched with Tongtai’s 55-ton newly developed batch grain dryer.

Stable indirect heating

It is positioned for indirect hot-air heating, stable pellet combustion, and reliable hot-air delivery for larger batch drying applications.

Practical medium-scale range

The current source set presents it as a medium-scale solution that can support larger batch dryers without moving to a much larger furnace class.

Key Features

Core engineering and control features documented in the current source set.

Full-Automatic Piston Feeding

Automatic piston feeding supports consistent pellet supply and reduced manual intervention.

Automatic Ash Cleaning

Automatic cleaning with manual assistance helps improve daily operating convenience.

Intelligent Constant-Temperature Control

The control logic is designed to maintain stable hot-air output under changing conditions.

Indirect Hot-Air Heating

Indirect hot-air heating helps keep the furnace suitable for grain drying support applications.

Safety Protection Package

The source set documents over-temperature, leakage, flameout, and fault-alarm protections.

Medium-Scale Dryer Matching

The model is described as suitable for matching with two medium dryers in standard scenarios.

Applications

Typical project scenarios where the 5L-80 is a good fit.

Medium-Scale Grain Drying

Suitable for medium-scale grain drying and hot-air applications.

Batch Grain Dryers

A strong matched heat source for Tongtai’s larger batch dryer configurations.

Drying Rooms

Can support drying-room and related hot-air demand in indirect-heating setups.

Related Hot-Air Projects

Appropriate where users need stronger pellet-based hot-air supply with practical automation.
