Atmos KC35S Coal Gasifier 35 kW

Product Overview & Application

The Atmos KC 35 S coal gasifier is a manually fed hot water boiler with 35 kW rated heat output for heating systems designed to use lignite briquettes as the primary fuel. It is suitable for buildings with a corresponding heat demand and is typically integrated into a water-based central heating system with a buffer tank.

Dry split logs can be used as an alternative fuel. The boiler output, chimney, return temperature boost, and buffer tank should always be sized appropriately for the system.

Technology & Equipment

The boiler operates on the principle of downdraft gasification with an induced draft fan. The boiler casing is made of welded steel sheets, the lower secondary combustion chamber is lined with ceramic, and the air supply is managed via primary and secondary air inlets.

Standard equipment includes an electromechanical control unit, a Honeywell FR 124 draft regulator, a boiler thermostat, a flue gas thermostat, a safety thermostat, and a cooling coil to prevent overheating. The rotating grate mechanism supports operation with coal and wood as an alternative fuel.

Everyday Advantages

The Atmos KC 35 S is designed for practical, robust heating operation with manually fed solid fuel. The induced draft fan supports the combustion process and reduces smoke development in the operating area when refueling.

The combination of a ceramic-lined combustion chamber, preheated air supply, and mechanical grate technology makes this boiler appealing to operators seeking a classic solid fuel boiler with a clear technical design.

System Integration & Compatibility

Operation requires integration with a return temperature boost system to achieve the necessary return water temperature. The boiler outlet temperature during operation ranges from 80 to 90 °C.

Installation with a buffer tank is intended for system operation. Additionally, chimney draft, flue gas routing, combustion air supply, and safety components must be planned and executed to match the heating system.

Installation

Installation is carried out as part of a water-based heating system with a suitable return temperature boost, flue gas routing, combustion air supply, and safety equipment. The boiler is intended for placement in a suitable boiler room and requires coordinated integration with the chimney, buffer tank, and heating circuit.

Notes

The primary fuel is lignite briquettes. Dry split logs can be used as an alternative fuel. For consistently clean operation, fuel quality, chimney draft, return water temperature, regular cleaning, and professional commissioning are crucial.
