nominal heat load

Calculation of the necessary power for heating liquids other than water. For the calculation you need the following information:

m = (mass) weight of the liquid to heat in kg / 1 litre water = 1 kg
c = (heat capacity) Coefficient of the liquid (Table book or a physics book)

heat load of the burner

From this table you can easily take the necessary heat load for heating water
(from 8 ° C - at 100 ° C).

Diameter of the hose for liquid gas

until about 10000 kcal/h = 11,5 kW: hose Ø 8 mm until L= 2000 mm
until about 16000 kcal/h = 18,6 kW: hose Ø 12 mm until L= 2000 mm

pressure for gas devices in Germany

natural gas: 20 mbar
liquid gas: 50 mbar

special design

We like to offer special designs according to specific customer requirements and technical requirements.

Please clarify in advance:

- Purpose
- What should be heated (surfaces, container,...)?
- Measurements with sketches (Take account of the combustion chamber)
- Which medium is heated (metal, liquid, air,...)?
- What max. Temperature should be achieved?
- In which time the temperature must be reached?
- how much power per hour?
- What type of gas is available?
- Brennerregulierung: manuell, thermostatisch, vollautomatisch?

Comprehensive technical calculation of gas burners are not contained in the prices of the burner. We offer engineer performance separately.

Technical info

All burners are valid under the rules of technology and manufactured in accordance with the DIN 4788. All components in the security area are certified.

The burners can be used for natural gas and liquid gas. A specialist company can easily adjust the devices with the conversion instructions.
