Double Burner Biogas Stove

Key Features

• Two biogas burners for simultaneous cooking.
• Independent flame controls for each burner.
• Biogas-compatible burner system designed for the characteristics of biogas.
• Stainless-steel cooking surface for durability and easy cleaning.
• Heavy-duty pot supports for stable placement of cookware.
• Compact tabletop design suitable for household kitchens.
• Easy-to-use control knobs for adjusting flame intensity.
• Durable metal construction suitable for regular cooking.
• Easy-clean surface helps simplify kitchen maintenance.
• Suitable for household and commercial applications.
• Can be integrated into a complete biodigester-to-kitchen energy system.

Main Functions

• The double burner stove is designed to:
• Provide cooking heat using biogas.
• Allow two cooking operations at the same time.
• Provide independent heat adjustment on each burner.
• Boil water and cook food simultaneously.
• Support frying, boiling, simmering, steaming and general meal preparation.
• Convert renewable biogas into useful thermal energy.

Benefits

1. Two Cooking Points

The two-burner configuration allows users to prepare multiple dishes simultaneously, helping improve kitchen productivity.

2. Makes Productive Use of Biogas

The stove provides a direct application for biogas produced from livestock manure, food waste and other suitable organic feedstocks.

Organic waste → Biodigester → Biogas → Gas treatment → Stove → Cooking energy

3. Convenient Flame Control

Each burner has its own control, allowing different cooking temperatures to be maintained simultaneously.

4. Reduced Dependence on Conventional Fuels

Where sufficient biogas is available, the appliance can provide an alternative source of cooking energy alongside or instead of conventional fuels.

5. Cleaner Cooking

Biogas combustion does not produce the smoke and ash associated with burning solid biomass such as firewood and charcoal. However, actual combustion emissions depend on burner design, gas quality, pressure and air–fuel mixing. Research shows that burner geometry and operating conditions have a significant effect on biogas combustion performance.

6. Suitable for Farms and Livestock Enterprises

The appliance is particularly useful where livestock waste is already being collected for anaerobic digestion.

7. Space Efficient

Two burners provide additional cooking capacity without requiring the footprint of a larger freestanding cooker.

8. Easy to Maintain

The relatively simple burner and control arrangement makes routine cleaning and inspection straightforward.

How the Biogas Stove Works

1. Organic material is fed into a biodigester.
2. Anaerobic digestion produces biogas.
3. The gas is collected and conveyed through the gas pipeline.
4. Where required, the gas passes through moisture and hydrogen-sulphide treatment equipment.
5. Conditioned biogas reaches the stove.
6. Opening a burner control allows biogas to enter the burner.
7. Biogas mixes with air before combustion.
8. The mixture burns at the burner ports.
9. The resulting flame transfers heat to the cooking vessel.

Recommended Applications

Installation Requirements

For proper operation, the stove should be connected to a properly designed biogas system.

Important installation considerations include:

• Adequate biogas pressure
• Correct gas-pipe size
• Appropriate gas-flow capacity
• Good-quality gas hose and connectors
• Moisture management
• Hydrogen-sulphide reduction where required
• Proper ventilation
• Leak-free connections
• Correct burner configuration

Safety Information

For safe operation:

• Use the appliance only with a suitable biogas supply.
• Ensure all gas connections are properly secured.
• Check the system for leaks before operation.
• Ensure adequate kitchen ventilation.
• Keep combustible materials away from the burners.
• Do not modify burner jets without technical guidance.
• Do not operate a damaged stove, hose or gas fitting.
• Turn off the gas supply when the stove is not in use.
• Keep children away from the appliance while operating.
• Investigate persistent flame instability, unusual flame colour or repeated flame-out.
