Double Burner Biogas Stove for Household Digesters

A two-burner tabletop stove built specifically for biogas from household and small farm digesters. Twin swirl-flame burners, individual control knobs and pulse ignition give a stable blue flame for everyday cooking, while the reinforced steel housing stands up to plant-side kitchen conditions. Model GN-MD 01, 710 × 400 × 130 mm.

Overview — cook on the gas your digester makes

A digester produces useful gas every day, but that gas only becomes a meal if the appliance at the end of the line is made for it. This double burner biogas stove is that appliance: two independently controlled burners on one reinforced steel top, with pulse ignition that lights the burner without a match or a separate lighter. Each knob controls its own burner, so one pot can simmer while the other boils, and the flame is trimmed with the same knob rather than by throttling the main gas valve.

The unit is designed as a tabletop cooker, not a built-in hob. It needs no cut-out and no cabinetry; it simply sits on a level, ventilated worktop and connects to the biogas line. The swirl-flame burner head spreads the flame around the base of the pot, and the raised pan supports hold a wok or a flat-bottomed pan steady. Because the stove is specified for biogas only, the burner and air mixing are matched to biogas rather than to natural gas or LPG — it should not be connected to any other gas supply.

Technical specifications

Values above are taken from the manufacturer's parameter sheet and are indicative, not a guarantee. Heat input, thermal efficiency, gas consumption, net weight, packaging dimensions and certification are not stated here and are available on request. No performance figures are published that are not shown on the parameter sheet.

Key features

• Two independent burners. Each burner has its own control knob, so two pots can be cooked at different flame settings at the same time — the practical minimum for a family kitchen.
• Pulse ignition. Press and turn the knob to light the burner. No matches, no open flame from a lighter, and no pilot flame left burning between meals.
• Reinforced steel housing. The thickened steel top and casing resist the knocks, heat and humidity of a plant-side kitchen and wipe clean after cooking.
• Built for biogas only. Burner ports and air mixing are matched to biogas. The stove is not intended for natural gas or LPG, which keeps the flame behaviour predictable on a digester line.

Applications

• Household digesters — the everyday cooking point for a family digester: boiling, frying and simmering on two burners from one tabletop unit.
• Farm and staff kitchens — a fixed cooking station near the plant, where the gas line is short and the appliance is used every day.
• Downstream of gas treatment — installed after the gas-water separator and desulfurizer, so clean, dry biogas reaches the burner.

Design and construction

The stove is a self-contained tabletop unit: a reinforced steel top carries two cast burner assemblies, each with its own pan support and control knob, over a shallow 130 mm casing. The swirl-flame cap distributes the flame around the pot base, and the air damper below the panel is used to correct a yellow or lifting flame. Non-slip feet keep the unit steady on a smooth worktop, and the smooth steel surface can be wiped down after cooking. It is supplied as a complete appliance with its accessory pack; configuration, packing and any project-specific adaptation are confirmed at quotation stage rather than assumed here.

Installation and safe operation

Place the stove on a level, well-ventilated worktop at least 15 cm away from the wall and clear of flammable materials, and keep the gas hose away from the hot underside of the casing. Connect a 9.5 mm biogas hose to the inlet with a clamp and check every joint for leaks before first use. Household digester lines are not pressure-regulated: if the line pressure rises above 5 kPa, fit a regulator and bring the supply into the 1.6–5 kPa working range before lighting. On a new digester the first gas in the line may be impure; purge it outdoors and repeat the ignition if the burner does not light at the first attempt. The knob returns to the vertical OFF position to extinguish the flame. If the flame turns yellow or lifts off the burner, adjust the air damper under the panel until it burns steady and blue.

Like every biogas appliance, the stove works reliably on clean, dry gas. A gas-water separator and a desulfurizer upstream of the stove protect the burner and the valve from condensate and hydrogen sulfide; the flame colour is a useful day-to-day indicator. Clean the burner head, flame cap and top panel periodically to remove carbon and residue.

Installation values above (15 cm wall clearance, 9.5 mm hose, 1.6–5 kPa working range) are taken from the product instruction manual, not from the manufacturer's parameter sheet. They are indicative installation guidance, not a guarantee or a performance commitment; confirm them against your project's actual gas conditions before commissioning. The five product parameters in the table above remain the only specification values used on this page.

Frequently asked questions

Q1. Can this stove run on natural gas or LPG?
No. The parameter sheet specifies biogas only. The burner ports and air mixing are set up for biogas, so the unit should be connected to a biogas line and not converted to another gas without the manufacturer's confirmation.

Q2. How is the stove lit?
It uses pulse ignition: press the control knob lightly and turn it until the burner lights. There is no pilot flame and no need for matches or a separate lighter. Details of the ignition power supply and spare parts are available on request.

Q3. Will it fit a standard kitchen worktop?
The panel size is 710 × 400 × 130 mm and it is a tabletop unit, so it sits on the work surface rather than being cut in. Allow clear space around it for ventilation and keep the gas hose away from the underside of the casing.

Q4. What preparation does the biogas line need?
A gas-water separator and a desulfurizer should be installed ahead of the stove. This keeps condensate and hydrogen sulfide out of the burner and valve, which is the most common cause of poor ignition and a yellow flame on small digester lines.
